Three-pole, line-protection version, no communication module, no voltage trigger, no ground-fault monitoring. The auxiliary contact pack is two HQ switches (3VA9608-0BB25) integrated from the factory. The undervoltage release (UVR) is present — so if your safety circuit drops the control voltage, this breaker opens without a separate shunt-trip command. The 76.2 mm width (three-pole, standard 25.4 mm per pole) and 130 mm height fit the 3VA frame footprint. Depth is 70 mm — that's the dimension from the mounting surface to the front of the breaker, so factor it into your enclosure depth clearance, especially with the rotary handle or door interlock if fitted. Keep it inside a panel with a sealed door for washdown environments. ## Thermal derating — the real continuous current at your ambient Above that, it derates: 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, 56.7 A at 70 °C. If your panel ambient runs at 60 °C, you lose about 4 A of headroom — plan your load accordingly rather than relying on the 63 A nameplate.","metaTitle":"Siemens 3VA1163-4EF36-0DC0 SENTRON MCCB, 63 A, 121 kA at 240","metaDescription":"Siemens 3VA1163-4EF36-0DC0 SENTRON molded case circuit breaker, 63 A rated, 121 kA at 240 V, TM240 release, 3-pole, 70 mm depth.
