CBCT
Circuit Breaker Coil Tester
The CBCT is a variable voltage DC power supply designed specifically to test substation circuit-breaker Open and Close coils. The CBCT uses the substation’s DC power supply to electronically generate a programmable output voltage from 5% to 95% of the source voltage. The CBCT can maintain up to an 80A test current while maintaining 2% or better voltage regulation during the circuit breaker coil operation.
- One continuous and one pulse DC output
- Back-lit LCD screen (20 characters by 4 lines)
- Output voltage programmable from 5% to 95% of the input voltage
- Built-in, single channel timer
