It carries a 187 kA interrupting capacity at 240 V and 121 kA at 415 V — numbers that tell you this breaker handles high-fault utility feeds without cascading upstream. The 800 V rated insulation voltage gives it headroom for 480 V and 600 V class systems common in North American and European industrial panels. Above that it steps down: 375 A at 55 °C, 350 A at 60 °C, 325 A at 65 °C, and 300 A at 70 °C. If your panel runs hot near the top of the gland plate, factor the 55 °C or 60 °C row into the BOM, not the 400 A nameplate. Interrupting capacity drops with system voltage: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V. That 17 kA at 690 V is the number to check if this breaker lands on a 690 V mining or marine distribution bus — it's still adequate for most downstream subfeeds but not for a main with high fault current. Dimensions are 248 mm high, 138 mm wide, 110 mm deep. No auxiliary contact version is fitted from the factory, but the slot accepts the 3VA9608-0BB25 auxiliary trip if you need remote status later. In a multi-breaker lineup, sum the losses and size the enclosure ventilation accordingly. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C, so it can sit in an unheated warehouse through winter without damage.","metaTitle":"Siemens 3VA2340-5JQ32-0DA0 SENTRON MCCB, 400 A, 3-Pole, Line","metaDescription":"Siemens SENTRON 3VA2340-5JQ32-0DA0 molded case circuit breaker, 400 A rated continuous current, 3-pole, line protection with ETU560 release, 187 kA at 240 V.
