Current Injection

We offer a range of secondary and primary current injection equipment, from 50A upwards, including both single phase and three phase.

Secondary Current Injection Equipment (SCITS)

 
 Our range of units covers applications up to 200A and includes single phase and three phase units with applications for testing and timing of IDMT relays, thermal overloads, MCB’s and auto-reclosers, and the 200ADM-P captures data directly to a USB memory stick.
