A comprehensive range of measuring ring current transformers for installation where reliability, accuracy and quality are required

Models:

MR SERIES MEASURING RANGE

MR transformers are used to accurately measure high alternating primary currents, converting the primary current into a proportional secondary current as required for measurement and instrumentation. They are available in 5 amp or 1 amp secondary versions

PR SERIES PROTECTION RANGE

The PR series is a range of two of the most popular classifications of protection current transformers, 5P10 and 10P10. Other Classifications are possible (such as 5P20 or 10P20).

CLASS PX CURRENT TRANSFORMERS

In some balanced protection systems where sensitivity and stability levels required are high, classes 5P10 or 10P10 may not be adequate. In these situations a Class PX current transformer will usually be specified. Class PX as defined in IEC60044-1/BS EN60044-1 allows the manufacturer of a protection device to detail more specific requirements of the current transformer so as to achieve a more sensitive protection scheme

MINIATURE CURRENT TRANSFORMERS

A range of Wedding ring Miniature Tape wound current transformers whose size permits PCB mounting. Designed to convert high currents to low level electronic signals. Available in tape wound with ring or foot mounting versions or in a moulded case

SC SERIES SPLIT CORE CURRENT TRANSFORMERS

A range of split core current transformers that offers a cost effective and efficient method by which the current can be measured without the need to break the conductor, thereby reducing installation and commissioning time

MINIATURE SPLIT CORE CURRENT TRANSFORMERS

Range of miniature split core current transformers that offers a cost effective and efficient method by which the current can be measured without the need to break the conductor, each current transformer is supplied with color coded leads of up to 3 meters for connection to the monitoring device. The MSC range of current transformers offers primary currents between 60-500A with 1 or 5A secondaries with class 1 accuracy performance. (Class 3 for 60-80A range).

3-IN-1 CURRENT TRANSFORMERS

A range of 3-in-1 current transformers combine three traditional current transformers in one moulded case. 3-in-1 current transformers can be directly installed next to a three-phase moulded case circuit breaker, thus saving installation time where fitting three standard individual current transformers would be required. The M3N1 range of current transformers offers primary currents between 60-630A with 5A secondaries with up to Class 0.5 accuracy performance

DIN-RAIL ENCLOSURE 3-IN-1 CURRENT TRANSFORMERS

A range of 3-in-1 current transformers combine three traditional current transformers in one Low profile DIN-rail enclosure. 3-in-1 current transformers can be directly mounted onto a DIN-rail, thus saving installation time where fitting three standard individual current transformers would be required. The 3-in-1 range of current transformers offers primary currents between 50-250A with 5A secondaries with up to class 0.5 accuracy performance.

THREE-PHASE DIN-RAIL KWH ENERGY METERS (DIRECT CONNECTION)

This four DIN module kWh energy meter measures the real consumption of active energy. The module meter has the highest accuracy class (1) with easy wiring, back illuminated LCD display. This module passes the load cable through the case allowing up 100A direct connection on a three-phase system. MID approved, cost effective, simple navigation, integrated with two pulse outputs.

DUAL LOAD 3-IN-1 CURRENT TRANSFORMERS
