Three Phase Current Transformer

Three Phase Current Transformer

Three phases  Current Transformer(M3N1)

3 in 1 current transformer is designed for used at the top of MCCB,the current transformer save a lot space and time.

Three phases (M3N1) current transformer suitable for primary ranged from 100A to 1200A with 5A secondary. Allowing installation directly on top of moulded case circuit breakers for greater speed of installation and optimisation of space. Applicable MCCB: ABB Isomax series, Merlin Gerlin NS series, CM1 series.
