Rated 59 A at both 480 V and 600 V, with a breaking capacity of 30 kA at 400 V and 100 kA at 240 V. That 30 kA at 400 V means it can safely interrupt a fault current up to 30,000 A on a 400 V line — enough headroom for most industrial distribution panels without needing an upstream current-limiting fuse.
Panel fit and clearances
Dimensions: 149 mm deep, 55 mm wide, 140 mm tall. The 55 mm width is a three-module footprint on the DIN rail — common for this class of motor-protective breaker. At 400 V, the upward clearance must be 160 mm for arc flash containment; at 500 V it's 125 mm, at 690 V it's 100 mm. At 240 V no clearance is required. Plan the gland plate and busbar routing accordingly. Terminals accept 2x (1 to 35 mm²) or 1x (1 to 50 mm²) solid or stranded copper — M6 main contact screws.
Operating conditions and ratings
Rated operating voltage range 20 to 690 V. No ground fault detection, no phase failure detection built in — this is a straight thermal-magnetic or electronic motor-protective breaker; external monitoring is needed if those functions are required.
