Description

Built for high-load feeders, this moulded case circuit breaker pairs a compact fixed 3-pole frame with an 18 kA breaking capacity at common AC voltages. It suits new builds and retrofits, and for turnkey boards it integrates neatly with our industrial panel fabrication to standardize layout and wiring.
