That kind of SCCR headroom means you can use it as a main breaker in a panel feeding multiple subfeeds, not just a branch device. Thermal derating is published from 40 °C through 70 °C: it holds 125 A up to 50 °C, then drops to 120 A at 55 °C, 117.5 A at 60 °C, 115 A at 65 °C, and 112.5 A at 70 °C. An undervoltage release (UVR) is integrated — order code 3VA9608-0BB25 for the auxiliary trip — so the breaker drops out on loss of control voltage, which is common in safety circuits or emergency-stop chains that need a shunt trip on undervoltage. No auxiliary contact module is fitted as standard. Dimensions are 70 mm deep, 76.2 mm wide, 130 mm tall — a standard 3-pole MCCB footprint that drops into most SENTRON distribution panels and switchboard cubicles without re-drilling.","metaTitle":"Siemens 3VA1112-6EF36-0DA0 SENTRON MCCB, 125 A, 220 kA at 24","metaDescription":"Siemens SENTRON 3VA1112-6EF36-0DA0 molded case circuit breaker, 125 A rated, 3-pole, TM240 release, 220 kA at 240 V.
