Maximum power loss is 96 W — that's the heat you need to vent in a closed enclosure, especially if the breaker is running near its full rating in a high-ambient cabinet. Latching endurance is 15 000 cycles; operating temperature range is -25 °C to 70 °C, storage -40 °C to 80 °C. ## Mounting and integration — fits a standard MCCB footprint That's a standard 3-pole MCCB envelope for panel mounting — no special adapter plate needed for most switchboard or enclosure cutouts. The shunt trip (STL) and two auxiliary switches (HQ) are factory-installed; verify the wiring diagram for your control voltage before landing the coil wires.","metaTitle":"Siemens 3VA2340-7HL32-0JC0 SENTRON MCCB, 400 A, 3-pole, ETU3","metaDescription":"Siemens SENTRON 3VA2340-7HL32-0JC0 molded case circuit breaker, 400 A rated continuous current, 3-pole, ETU320 release, 330 kA at 240 V.
