The 100 A frame holds that rating across the 40 °C to 50 °C band, then derates to 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C (–). Auxiliary contacts are two HQ switches. ## Panel fit The depth of 86 mm means it clears most standard enclosure depths, but check your gland plate clearance if the breaker sits near the door.","metaTitle":"Siemens 3VA2110-5MN32-0BC0 SENTRON MCCB, 100 A, Motor Protec","metaDescription":"Siemens 3VA2110-5MN32-0BC0 SENTRON molded case circuit breaker, 100 A rated continuous current, 3-pole motor protection with ETU350M trip unit.
