Breaking capacity climbs with the voltage drop: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 7.5 kA at 690 V. It's a 3-pole unit, designed for line protection, with a built-in communication function for remote monitoring or integration into a BMS or SCADA system. The trip indicator gives a local visual when the breaker has opened on fault — saves chasing a downstream short blind. That 110 mm depth is the key fit number for shallow enclosures — measure your backpan-to-door clearance before ordering. ## Thermal and electrical endurance Maximum power loss is 96 W at rated current. That's the heat you need to vent from the enclosure — plan for it in the thermal budget, especially if the breaker is grouped with other high-current devices. That -25 °C floor means it's fine for unheated turbine nacelles or outdoor substations in most temperate climates, but if your site sees -30 °C regularly, you need the cold-rated variant.","metaTitle":"Siemens 3VA2340-6JP32-0AG0 SENTRON MCCB, 400 A, 3-Pole","metaDescription":"Siemens 3VA2340-6JP32-0AG0 SENTRON molded case circuit breaker, 400 A continuous, 3-pole, up to 242 kA breaking capacity at 240 V.
