Product details

400 A line-protection MCCB with high interrupting capacity

The Siemens SENTRON 3VA2340-6KP32-0BL0 is a 3-pole molded case circuit breaker (MCCB) rated for 400 A continuous at 40 °C, with a trip unit adjustable between 600 A and 4 000 A. The breaking capacity reaches 242 kA at 240 V AC and 187 kA at 415 V, tapering to 7.5 kA at 690 V — this is a distribution-class breaker sized for high-fault main feeders, not motor branch circuits.

Current ratings and thermal derating

The breaker holds 400 A continuously up to 50 °C ambient. Above that, derating is linear: 375 A at 55 °C, 350 A at 60 °C, 325 A at 65 °C, and 300 A at 70 °C. Maximum power loss is 98.5 W.

Frequently asked questions

What is the closest functional second-source to 3VA2340-6KP32-0BL0?

The peer 3VA2116-5JP32-0AE0 is a lower-current variant in the same SENTRON 3VA platform. It shares the same frame style and accessory architecture, but the trip rating and breaking capacity differ — a direct drop-in without recalculating selectivity and SCCR is not advised.
