Description

Designed for 125 A feeders, this moulded case circuit breaker pairs a compact fixed 3-pole frame with an 18 kA breaking capacity at common AC voltages. It fits new builds and retrofits, and for turnkey boards it aligns cleanly with our industrial panel fabrication to standardize layout and wiring.
