Product details

The Siemens SENTRON 3VA2340-6JQ32-0CC0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying a full-scale current of 400 A and an adjustable thermal-magnetic trip range from 600 A minimum to 4000 A maximum. Its interrupting capacity hits 242 kA at 240 V AC and 187 kA at 415/440 V, dropping to 121 kA at 500 V and 7.5 kA at 690 V — so for most 400 V class distribution panels this breaker clears faults well into the high-fault zone without cascading upstream.

Thermal derating and ambient compensation

Above that it derates linearly: 375 A at 55 °C, 350 A at 60 °C, 325 A at 65 °C, and 300 A at 70 °C.

Auxiliaries and communication

This variant ships with two HQ auxiliary switches and an undervoltage release (UVR) fitted. Communication function is onboard, so it can report status or accept remote commands over the SENTRON bus system.
