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.","metaTitle":"Siemens 3VA1110-6FE42-0AA0 SENTRON MCCB, 100 A, 4-Pole, 220","metaDescription":"Siemens SENTRON 3VA1110-6FE42-0AA0 molded case circuit breaker, 100 A rated continuous current, 4-pole, line protection, TM220 release.
