Product details

Rated at 65 A (AC-3) with a breaking capacity of 50 kA at 400 V, this breaker handles motor loads up to 18.5 kW at 230 V or 50 hp at 460/480 V. Built-in phase failure detection ensures the breaker trips if one phase drops out, preventing single-phasing damage to the motor. No ground fault detection, so that function must be handled separately if required.

Any mounting position is permitted, which simplifies panel layout. Clearance requirements: 50 mm upward, 50 mm downward, and 10 mm to the side — plan your DIN rail spacing accordingly. Dimensions: 55 mm wide, 140 mm high, 149 mm deep. The 55 mm width occupies three standard 18 mm DIN modules — factor that into your enclosure fill calculations. Screw-type terminals on the main circuit accept 2×(1…35 mm²) or 1×(1…50 mm²) solid or stranded wire, with M6 bolts for the main contacts.
