At 240 V it interrupts 187 kA; at 415 V that drops to 121 kA, and at 690 V it holds 17 kA. The interrupting capacity falls off sharply above 440 V, so verify the available fault current at your system voltage before committing the BOM line. The thermal derating curve is flat to 50 °C — still 100 A — then drops 2 A per 5 °C step through 70 °C, where it's 91 A. If your panel ambient runs above 50 °C, size for the derated figure, not the nameplate. The 25 W maximum power loss at full load matters for enclosure heat rise calculations; that's not trivial in a sealed cabinet. Rated insulation voltage is 800 V, so it's suitable for 690 V systems with margin. IP40 on the front means it's protected against tools and wires >1 mm — standard for a panel-mounted breaker, but not for washdown zones. No undervoltage release, no ground-fault monitoring, no communication function on this variant — it's a straight line-protection breaker, not a smart or accessory-loaded unit. ## Panel fit and mounting The breaker measures 101.6 mm wide by 130 mm tall by 70 mm deep — that's a 4-inch wide footprint, which is standard for a 4-pole 100 A MCCB in the SENTRON 3VA platform. It mounts on a DIN rail or can be screw-fixed to a backplate; the IP40 front allows it in a standard enclosure without a sealed door.","metaTitle":"Siemens 3VA1110-5GE42-0AA0 SENTRON MCCB, 100 A, 4-Pole, TM22","metaDescription":"Siemens 3VA1110-5GE42-0AA0 SENTRON molded case circuit breaker, 100 A, 4-pole, TM220 thermal-magnetic trip, 187 kA at 240 V.
