For a 230 V AC single-phase supply, that covers the vast majority of domestic and small commercial service-entrance faults. Rated operational voltage is 230 V AC, with a maximum of 250 V in single-phase operation. Frequency range is 50/60 Hz. For DC applications the maximum rated voltage is 72 V — useful if you're protecting a small DC subcircuit, but this is primarily an AC breaker. Power dissipation is 2.8 W per pole in hot operating state at rated current. In a multi-breaker enclosure, that adds up — account for it in thermal calculations if you're packing several units side by side.
Physical integration and mounting
Height is 90 mm. Sealable cover is standard; halogen-free and silicon-free construction. IP20 protection with connected conductors — fine inside a distribution board or enclosure.
