Description

Purpose-built for 20 A feeders, this moulded case circuit breaker pairs a compact fixed 3-pole frame with a high 36 kA breaking capacity at common AC voltages. It fits cleanly into new or retrofit boards, and for turnkey assemblies it integrates smoothly with our industrial panel fabrication to standardize layout and wiring.
