Standard current transformersWe have a full range of primary and secondary currents available. Types available include :-
Dimensions for Split-core CTs are available for
|
|
Moulded CTsThese are low cost moulded case CTs with built-in sealable terminal covers. Secondary current is 5A and available primary currents are in the range 50A to 300A. Class 1 accuracy. CTR Range Click here

3-in-1 3-phase CTs (up to 250A)These moulded case CTs combine 3 separate CTs in one case. Supplied with terminal cover and a choice of fixings. Secondary current is 5A and available primary currents are in the range 100A to 250A per phase. Class 1 accuracy. Suitable for round cable or 21mm busbars, the case width of 105mm allows direct mounting on moulded case circuit breakers. CT105 Range Click here

3-in-1 3-phase CTs (400 to 630A)These moulded case CTs combine 3 separate CTs in one case. Supplied with terminal cover and a choice of fixings. Secondary current is 5A and available primary currents are in the range 400A to 630A per phase. Class 1 accuracy. Suitable for round cable or 31mm busbars, the case width of 140mm allows direct mounting on moulded case circuit breakers. CT140 Range Click here

Fused Voltage Terminal with Integral CTThe new SHM CTV Power Sensor combines three functions in one module - a rail-mounting terminal, a fuse and a current transformer. Its unique design saves space, time and money. Secondary current is 1A and available primary currents are in the range 16A to 64A. Breaking capacity is 70kA at 400V 50Hz. CTV Range |

Hobut Clip-on CTsSplit-core CT supplied in a moulded case with 1m flying leads. Secondary current is 5A and available primary currents are in the range 150A to 800A. Class 1 accuracy. Can be installed into existing networks without disconnecting cable circuits. The fast-action clip ensures high-speed permanent installation. CTSC Range Click here

Mini-ClipThe Mini-Clip is an ideal solution where space limitations mean conventional CTs cannot be used, for example in crowded distribution boards. With its one-click operation and cable ties to secure it to the conductor, it is ideal for difficult retro-fit applications. Secondary current is 1A and available primary currents are in the range 60A to 200A. As a direct consequence of its small size, the accuracy is Class 3, so for metering applications the load needs to be close to unity power factor. Hence it is not really suitable for tariff metering.

Class 1 Mini-ClipThe Mini-Clip is an ideal solution where space limitations mean conventional CTs cannot be used, for example in crowded distribution boards. With its one-click operation and cable ties to secure it to the conductor, it is ideal for difficult retro-fit applications. Secondary current is 1A for primary currents up to 200A and 5A for currents 200A and above. These CTs are slightly larger than the standard MiniClip range, and meet IEC60044-1 Class 1 accuracy requirements. Mini-Clip Range Click here
