Description

Designed for 20 A feeders, this moulded case circuit breaker pairs a compact 3-pole fixed frame with a high 25 kA breaking capacity at common AC voltages. It fits new builds and retrofits, and for turnkey panels it integrates neatly with our industrial panel fabrication to standardize layout and wiring.
