It protects branch circuits against overload and short-circuit in final distribution panels, typically in commercial or light industrial installations where the inrush current of connected loads (e.g., small motors, fluorescent lighting banks) is moderate. Rated at 400 V AC, the breaker carries a 4.5 kA breaking capacity per EN 60898, a 6 kA rating per IEC 60947-2, and a 5 kA rating per UL 1077 / CSA C22.2 No.235.
IP20 protection with connected conductors — the terminals are touch-safe when wired, but the breaker is not sealed against dust or moisture ingress. Degree of pollution 3 means it is rated for conductive pollution environments typical of industrial control rooms (not clean labs).
