The 690 V rating drops to 17 kA, which still covers most 690 V motor circuits but needs a selectivity study if the available fault current exceeds that. ## Thermal derating — don't size by the nameplate alone At 55 °C it derates to 96 A, then 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C. A panel builder stuffing this into a high-ambient enclosure — say, a non-vented MCC bucket near a drive — must apply that curve. The TM240 release is adjustable for the long-time pickup, so you can fine-tune the trip point within the thermal-magnetic band without swapping the breaker. ## Auxiliary contacts and status feedback The trip indicator on the front gives the field service tech a quick visual check without needing a meter. No communication module, no phase-failure detection, and no undervoltage release are fitted on this variant.","metaTitle":"Siemens SENTRON 3VA1110-5EF32-0AF0 MCCB, 100 A, 3-Pole, TM24","metaDescription":"Siemens 3VA1110-5EF32-0AF0 SENTRON molded case circuit breaker, 100 A rated, 3-pole, TM240 thermal-magnetic release. 187 kA at 240 V.
