Breaking capacity is the headline number for fault coordination: 330 kA at 240 V AC, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 7.5 kA at 690 V. At 415 V, the 242 kA rating means it can be placed upstream of a transformer or busway with very high available fault current — typical for large industrial switchboards — and still maintain selectivity with downstream devices. The 3-pole design and motor protection designation mean this MCCB is intended for three-phase motor branch circuits. Time-delay settings span 4 s minimum to 17 s maximum, which governs the short-time pickup and delay for coordination with downstream feeders. A 17 s delay at low overcurrents lets downstream breakers clear a fault first, maintaining selectivity. The maximum power loss is 37.5 W — relevant for thermal management inside a sealed enclosure.
Dimensions are 110 mm depth, 138 mm width, and 248 mm height. This is a standard SENTRON 3VA2 form factor, designed for panel-mount or DIN-rail installation in a distribution board or motor control center. The 138 mm width fits a 3-pole MCCB footprint common across the 3VA2 family.
