The current sensor CT125 consists of three precision current transformers (CT)

The current sensor CT125 consists of three precision current transformers (CT), a precise residual current transformer (RCT) and a processing circuit, connecting M200 series of motor protection devices via a 9-Pin DB9 cable.

CT  : 6, 10, 32, 50,100, 200, 315A
RCT : 0.1~10.0A

Notes:
1.CT125A: without RCT, earth protection not supported
2.CT125B: with RCT, earth protection supported
3.Standard length of cable: 1.5 meters, otherwise specified
