The 63 A rating holds flat from 40 °C through 50 °C, then derates to 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C — so in a warm enclosure you lose only a few amps before the thermal curve bites. Breaking capacity runs 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. That 75.6 kA at 240 V gives headroom for high-fault industrial services; the 11.9 kA at 690 V is still adequate for most 690 V distribution. Width 76.2 mm, height 130 mm, depth 70 mm. ## What the TM240 release and shunt trip mean for coordination The TM240 overcurrent release is a thermal-magnetic type with a 240 A frame rating — the breaker itself is 63 A, so the release is set for a lower continuous current within the frame's capacity. That means you can uprate the breaker later by swapping the release without changing the entire MCCB, as long as the frame and bus bars support it. The shunt trip (STL) is a separate auxiliary release that requires a control voltage to trip; it's not an undervoltage release (that's a different variant).","metaTitle":"Siemens 3VA1163-3EF36-0KA0 SENTRON MCCB, 63A, 3-Pole, 75.6kA","metaDescription":"Siemens SENTRON 3VA1163-3EF36-0KA0 molded case circuit breaker, 63A rated at 40°C, 3-pole, 75.6kA breaking at 240V.
