Range 5 to 30kVAr.


Modules - (C88) - Fixed power factor correction in a modular assembly. The modularity of C88 family enables obtaining the needed reactive power by properly combining several modules with a simple and fast electric and mechanical link.


Racks - (C91) - Designed for OEM customers, these pre-wired sub-assembly racks offer easy incorporation into power factor correction cubicles, either stand-alone or inside main low voltage switchboards. They are provided with mechanical runners, contactors and 100KA fuses. Suitable for highly harmonic polluted plants, the range includes various combinations of stages with standard racks up to 100kVAr and de-tuned racks up to 50kVAr.


Fixed Cubicles - (C9BS) - Suitable for individual load applications where correction is best applied at source. Units are housed in a steel enclosure with robust power terminals and power indication. Available with or without a main switch. Standard range up to 75kVAr.


Mini Automatic Cubicles - (C94) - This range offers a compact and space saving design complete with door interlocking isolator and digital control relay for flexible control. Floor standing and wall mountable with top cable entry. Protection degree IP30 with closed doors, IP20 on the parts under voltage with open doors. Incredible value for money on this range. Available up to 200kVAr.


Automatic Cubicles - (C92) - Automatic PFC equipment suitable for medium and heavy industrial plants. They are provided with a suitably rated door interlocking isolator but can be upgraded to a switch-fuse or circuit-breaker. The range is available as standard or fitted with harmonic blocking reactors for anti-resonance systems. Manufactured with top or bottom cable entry and can be custom built for expansion in the event of further correction being required. Panel mounted man/off/auto switches with indicator lamps and IP54 filters are available as low cost options.


Digital Control relays - (DPF) - Industrial plants with time-varying absorption require control relays to connect and disconnect the capacitive power required. The DPF series of control relays are designed to secure accurate control of all the electrical parameters: Voltage, Current, Cosj, Thd % in current, Ambient Temperature (probe), Active, Reactive, Apparent Powers, max values extracted from measurements or through a reliable calculation algorithm. Achieve optimal usage of contactors and capacitors by taking into account the phenomena of distortion typical in industrial plants. All models in this range can be set up for single or three phase systems.


Harmonic Blocking Reactors - (M6T35) - Especially conceived and designed for racks and automatic power factor correction equipment installed in networks with a high harmonic load. With high linearity and tuned to the capacitors, these reactors ensure a lengthy service life, extremely low losses and low noise emission during operation. Their working principle consists of translating the resonance frequency of the installation under the harmonic to a lower magnitude so as to avoid triggering phenomena of resonance. The range can be tuned to 189Hz (p=7%) or 133Hz (p=14%), when the problematic 3rd harmonic may be present.


Control Transformers - (SCL) - Double wound with earth screen between windings. Frequency range 50/60 Hz. Terminal block connection. Good access to fixing flanges. Continuous duty. full varnish impregnation for silent running. Conforms to EN60742, IEC742, IEC61558.


Contactors - (UA) - Contactors used in the automatic panels are specifically designed for capacitive loads, and for this reason are provided with pre-insertion resistors and reinforced special contacts. Contactors must be sized according to the rating of the capacitor bank it’s switching and the control voltage should be specified when ordering.


Thermostats - (KT) - Ensure components are operating within their approved temperature range by maintaining the minimum and maximum conditions within cabinets. These DIN rail mountable thermostats have control ranges of -10 to +60 degrees °C and can be used with heaters or fans.


Fuses - (NH) - Fuses with top and combination indicator are available in a large variety of voltage ratings, body sizes and operating classes. Only use superior quality fuses for cooler running and efficiency when installed with capacitors.


Fuse Bases – (NH) – Ceramic and Polyester fuse blocks are available in single pole configurations with or without finger-safe covers. Fuse blocks come standard with stud connectors for ease of wire termination. All fuse clips are silver-plated copper and fuse clips are spring re-enforced for superior conductivity.


Fuses - (Cylindrical) - A wide range of physical sizes and ampere ratings for 250, 400, 500, and 690 volts AC. Most ratings are available with an optional indicator and all industrial fuse-links have the option of a built-in striker. All cylindrical fuse-links have ceramic bodies and silver-plated ferrules.


Fuse Holders – (Modular) – Ultra safe fuse holders qualify as "finger safe" to an IP20 grade of protection, including fuse changing (with the flick of a finger). Ultra safe fuse holders are available in 1, 2, 3 or 4 poles, with or without visual blown-fuse indicators in each pole. Save up to 15% mounting space and any combination can be snapped onto 35mm DIN rail for extra savings in panel building time. The body material is tough and durable polyamide, with exceptional insulating properties.


Resistors - (220kΩ) - Safety discharge resistors for capacitors are dimensioned to discharge the capacitors in the time and to the voltage foreseen by the CEI EN 60831-1/2.


Current Transformers - (DM) - Installed in electric installations to reduce the line current to a secondary value of 5A, which is compatible with current inputs of control relays and digital multimeters. The number of loops of the primary cable does not modify the accuracy but converts the primary current value proportional to secondary current. Both Solid and split-core versions available and can be installed on cable or bus-bar. Primary current values start from 50A upwards.


Cable - (Tri-rated) – Single core electrical cable specifically designed for use in panel building and installation into conduit. Electrolytic annealed copper conductors covered with flame retardant high temperature PVC insulation. Tri-rated Cable is often referred to more generally as panel wire, switchgear cable, T.R.S (tri-rated singles) or BS 6231 Cable.


Cable – (YY) - Ideally suited for use as control, signal and power cables in a variety of applications. Its high flexibility ensures easy installation whilst the tough external sheathing will resist the effects of many acids, caustic solutions and various oils. Cores are black with white numbers and one green/yellow, coloured core option also available.


Cable – (SY) - Has the added protection of a galvanised steel wire braid and transparent PVC outer sheath. It retains flexibility and ease of installation and offers a high degree of mechanical protection often extending the service life of an installation. Cores are black with white numbers and one green/yellow, coloured core option also available.


Terminals - (Pre-insulated) - A wide range of crimps and connectors made from high grade PVC insulation ensuring complete integrity of final crimp. The sturdy steel body ensures a reliable electrical connection.


Terminals - (Copper Tube) - All types manufactured from electrolytic copper tube. The terminals are designed to obtain the most efficient electrical conductivity and mechanical strength to resist vibration pull out.


Cable Markers - (PA) – Secure identification marker sleeves for unconnected wires and cables. Designed to interlock when fitted, enabling easy alignment of multiple character markings.


Neoprene Rubber Sleeves - (SES) - Extremely flexible plain cut sleeves with a wide range of sizes and colours available. The sleeves are ideally suited for the binding of cable and due to the materials elastomeric properties, a high degree of expansion can be achieved during assembly. The material is based on Polychloroprene with good elastic and mechanical properties; it is petrol and oil resistant and is not corrosive to metal.
