Product details

What this MCCB carries

The Siemens SENTRON 3VA2340-7HL32-0CA0 is a 3-pole molded case circuit breaker (MCCB) rated for 400 A continuous current at 40 °C ambient, with a thermal derating curve that holds 400 A through 50 °C, then drops to 385 A at 55 °C and 340 A at 70 °C. Breaking capacity runs 330 kA at 240 V, 242 kA at 415/440 V, 187 kA at 500 V, and 7.5 kA at 690 V — covering most LV fault-current scenarios downstream of a transformer. An undervoltage release (UVR) is built in; no auxiliary switch or ground-fault module is fitted on this variant.

Panel fit and footprint

At 110 mm deep × 138 mm wide × 248 mm tall, this breaker fits standard SENTRON 3VA mounting bases and busbar systems. The 138 mm width is a 3-pole frame — verify gland-plate cutout if retrofitting into a panel originally laid out for a different MCCB family. Depth is shallow enough for 200 mm-deep enclosures; no rear-access clearance needed beyond the standard 50 mm arc-chute vent gap.

Frequently asked questions

What is the breaking capacity of this MCCB at 240 V?

330 kA at 240 V, derating to 242 kA at 415/440 V, 187 kA at 500 V, and 7.5 kA at 690 V.

Does this breaker include an undervoltage release?

Yes, an undervoltage release (UVR) is included. No auxiliary switch or ground-fault module is fitted on this variant.
