The Siemens SENTRON 3VA1110-6FE42-0AA0 is a 4-pole molded case circuit breaker rated for 100 A continuous current at 40 °C, with a TM220 thermal-magnetic overcurrent release. At 415 V it still interrupts 154 kA, and at 690 V it holds 17 kA, so the part covers both 400 V and 690 V distribution tiers within the same frame.
Thermal derating and ambient range
Above that it derates linearly: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C.
Physical fit and mounting
The 4-pole width (101.6 mm) is the standard 4-module footprint for SENTRON 3VA frames — it occupies the same panel cutout as other 4-pole 3VA breakers.
Release design and protection profile
This is a line-protection variant, meaning it's configured for cable and busbar protection rather than motor or generator protection. The N-conductor protection is set to 50% of the phase rating, standard for 4-pole distribution.
