Product details

The Siemens SENTRON 3VA2040-6JQ36-0AA0 is a 3-pole molded case circuit breaker rated for 40 A continuous current at 40 °C through 70 °C, with no derating across that span.

Breaking capacity is 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V.

It fits standard panel-mount cutouts for 3-pole MCCBs in distribution boards or motor control centers. The communication function allows it to report status over a fieldbus or digital I/O link, reducing the need for separate auxiliary contact blocks in monitored panels.
