This breaker clears 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 9 kA at 690 V. The 9 kA at 690 V tells you it's not meant for 690 V primary distribution, but at 400/415 V it's well above typical panel SCCR requirements. ## Thermal performance and derating That's a solid thermal design; many MCCBs start tapering off above 50 °C. ## Auxiliaries and releases Depth of 110 mm keeps it clear of shallow gland plates.","metaTitle":"SENTRON 3VA2440-5MN32-0HC0 MCCB, 400 A, 3-Pole, Motor Protec","metaDescription":"SENTRON 3VA2440-5MN32-0HC0 molded case circuit breaker, 400 A at 40 °C, 3-pole, motor protection, 187 kA at 240 V.
