Product details

What this MCCB carries on the nameplate

The Siemens SENTRON 3VA2340-6HL32-0AC0 is a 3-pole molded case circuit breaker rated for 400 A continuous current at 40 °C, with the ETU320 electronic overcurrent release handling line protection duty. Breaking capacity hits 242 kA at 240 V, 187 kA at 415 V, and still holds 40 kA at 690 V — so it clears high-fault scenarios across common industrial voltage levels without cascading upstream.

The 400 A rating holds flat from 40 °C through 50 °C, then drops to 385 A at 55 °C, 370 A at 60 °C, 355 A at 65 °C, and 340 A at 70 °C.

The 2 HQ auxiliary switches are built in for status feedback to the PLC or alarm circuit.

Frequently asked questions
