Siemens SENTRON 3VA4111-6ED34-0AA0 — 110 A MCCB with TM210 Release
The Siemens SENTRON 3VA4111-6ED34-0AA0 is a 3-pole molded-case circuit breaker (MCCB) rated for 110 A continuous at 40 °C, with a TM210 thermal-magnetic overcurrent release.
The continuous current rating is temperature-dependent. At 40 °C the breaker carries 110 A; at 50 °C it derates to 106 A; at 60 °C to 101 A; at 70 °C to 97 A.
Interrupting Ratings and Selectivity
At 600 Y/347 V the rating drops to 25 kA. For a 480 V panel with an available fault current of, say, 50 kA, this breaker provides headroom. The TM210 release has a fixed instantaneous pickup (Ii) of 1100 A — ten times the continuous rating — which is typical for a thermal-magnetic MCCB protecting a feeder or large motor branch. The adjustable long-time (Ir) range is not listed, so the TM210 likely has a fixed thermal element calibrated at 110 A.
Dimensions are 76.2 mm wide, 129.4 mm tall, and 75.1 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures. No neutral conductor upgrade or ground-fault monitoring option is available on this variant.
