For a 400 V panel, 187 kA gives you headroom to coordinate with a downstream 25 kA or 36 kA MCCB without the main tripping on a feeder fault — selectivity stays intact. ## Trip unit and protection features The ETU330 electronic trip unit supports adjustable long-time pickup, short-time pickup, and instantaneous settings. It also includes ground-fault monitoring via summation current formation on the L-conductor — meaning it sums the phase currents to detect leakage to earth, which is useful on IT or TN-S systems where you want early warning before a bolted fault develops. No trip indicator, undervoltage release, or communication module is built in; those are external accessories if needed. The optional motor drive (product extension) allows remote charging for applications like generator paralleling or automatic transfer schemes. The 40 A rating at 70 °C means this breaker doesn't force you to oversize the bus for a hot switchroom — it holds full rating up to that ambient. The IP40 front protection is standard for enclosed panels; if the breaker is mounted in a washdown area, the enclosure itself handles the IP rating, not the breaker face.","metaTitle":"Siemens 3VA2140-6HM36-0AA0 SENTRON MCCB, 40 A, 3-Pole, ETU33","metaDescription":"Siemens 3VA2140-6HM36-0AA0 SENTRON molded case circuit breaker, 40 A continuous, 3-pole, ETU330 electronic trip unit.
