The TM240 release provides thermal protection for overloads and magnetic (instantaneous) protection for short circuits — a standard thermal-magnetic curve, no electronic adjustment. This is a fixed-release MCCB, not a trip-unit-swappable frame. Maximum power loss is 17.3 W. In a sealed enclosure with multiple breakers, that heat adds to the internal temperature rise — the derating curve from 63 A at 40 °C down to 58 A at 70 °C accounts for this. Panel builders should factor the cumulative dissipation when sizing ventilation.","metaTitle":"Siemens SENTRON 3VA1163-4EF36-0AG0 3-pole MCCB, 63 A, 121 kA","metaDescription":"Siemens SENTRON 3VA1163-4EF36-0AG0 molded case circuit breaker, 3-pole, 63 A rated at 40 °C, 121 kA breaking capacity at 240 V.
