The interrupting ratings are hefty: 187 kA at 240 V, 121 kA at 415 V and at 440 V, then 75.6 kA at 500 V, and 7.5 kA at 690 V. The ETU850 electronic release gives you adjustable long-time, short-time, and instantaneous pickup, plus ground-fault alarm (not trip) capability; the undervoltage release (fitted) lets you drop the breaker on loss of control power, common in safety circuits. There's no auxiliary contact on this variant, so if you need status feedback to a PLC, plan on adding one separately. The breaker measures 138 mm wide by 248 mm tall by 110 mm deep. It includes a communication function.","metaTitle":"Siemens 3VA2340-5KP32-0CA0 SENTRON MCCB, 400 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2340-5KP32-0CA0 molded case circuit breaker, 400 A at 40 °C, 3-pole, ETU850 release, 187 kA at 240 V.
