Product details

Rated for the high-fault panel

The Siemens SENTRON 3VA2440-7HL32-0KH0 is a 3-pole molded case circuit breaker rated for a continuous current Iu of 400 A, with a breaking capacity of 330 kA at 240 VAC. The breaking capacity scales down as voltage rises: 242 kA at 415/440 V, 187 kA at 500 V, and still 52.5 kA at 690 V, which covers most industrial distribution voltages. The ETU320 electronic trip unit handles the overcurrent protection curve. The auxiliary release is a separate order: 3VA9688-0BL33.

Above that it derates: 384 A at 55 °C, 376 A at 60 °C, 368 A at 65 °C, and 360 A at 70 °C. That depth is the body only — factor in the shunt trip and auxiliary switch wiring clearance on the side.

Frequently asked questions

What is the breaking capacity of this MCCB at different voltages?

Breaking capacity is 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 52.5 kA at 690 V.

What trip unit does this breaker use?

It uses the ETU320 electronic overcurrent release, configured for line protection without ground-fault monitoring.

What auxiliary contacts and releases are included?

It includes a shunt trip (STL) for remote opening and an auxiliary contact block with 2 auxiliary switches plus 1 trip alarm switch (HQ). The basic switch is order code 3VA2440-7HL32-0AA0; the integrated auxiliary trip is 3VA9688-0BL33.
