That derating matters if you're packing this into a warm enclosure or a high-density switchboard row. Breaking capacity is the headline here: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 40 kA at 690 V. The 40 kA at 690 V still covers most industrial 690 V distribution. It uses an ETU850 electronic trip unit — that's the communicable version, so you get the communication function and other measurement functions built in, meaning it can talk to a BMS or SCADA for power monitoring and event logging. Maximum power loss is 96 W — that's the heat you need to vent in the enclosure. Latching endurance is 15 000 operations, which is typical for a line-protection MCCB; not a switching-duty device for frequent motor starts. Comes with 2 auxiliary switches (HP type) pre-installed. No trip indicator on the front — if you need visual trip indication, you'll add an external auxiliary contact or indicator module.","metaTitle":"Siemens 3VA2340-6KP32-0AB0 SENTRON MCCB, 400 A, 242 kA at 24","metaDescription":"Siemens SENTRON 3VA2340-6KP32-0AB0 molded case circuit breaker, 400 A rated continuous current, 242 kA breaking at 240 V.
