This is a straight electromechanical breaker for standard distribution and feeder protection.
Breaking capacity — the real coordination number
The breaking capacity tells you where this breaker can sit in a fault hierarchy. At 240 V it clears 187 kA; at 415 V it clears 121 kA; at 440 V it clears 36 kA; at 690 V it clears 17 kA. The drop to 36 kA at 440 V is still well above typical industrial panel SCCR requirements (usually 10–65 kA), so it gives headroom for coordination studies.
Thermal derating — don't size by the nameplate alone
At 55 °C it derates to 243.3 A; at 60 °C to 236.5 A; at 65 °C to 229 A; at 70 °C to 223 A.
Physical fit and auxiliary wiring
Dimensions: 140 mm wide, 158 mm high, 70 mm deep. That's a standard 4-pole MCCB footprint — it will fit most DIN-rail or panel-mount bases designed for the SENTRON 3VA platform.
