Rated continuous current holds flat at 400 A from 40 °C through 50 °C ambient, then derates to 385 A at 55 °C and 340 A at 70 °C. That thermal curve means the breaker delivers its full nameplate rating in a typical 50 °C panel interior without derating — a practical advantage when the enclosure runs warm from adjacent loads. That gives the controls integrator four discrete signals for status feedback — breaker ON/OFF, trip event, and a separate electrical alarm — without adding a separate contact module. Undervoltage release (UVR) is integrated — designated by the -0CL0 suffix — so the breaker drops out on loss of control voltage without an external relay. The UVR is factory-fitted to the supplied basic switch (3VA2340-7HN32-0AA0) and wired to the integrated auxiliary trip (3VA9608-0BB24). Maximum power loss is 98.5 W at rated load. That figure drives the ventilation or de-rating calculation for the enclosure — a panel builder sizing a sealed cabinet needs to account for that dissipation, especially when multiple breakers share the same compartment.","metaTitle":"3VA2340-7HN32-0CL0 SENTRON MCCB, 400 A, 3-Pole, Line Protect","metaDescription":"Siemens SENTRON 3VA2340-7HN32-0CL0 molded case circuit breaker, 400 A rated current, 3-pole, 330 kA breaking at 240 V.
