The TM240 overcurrent release gives it a fixed thermal-magnetic curve tuned for 63 A continuous duty at 40 °C through 50 °C, with a slight derating ladder above that: 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C. That derating profile matters if this breaker lives in a non-ventilated enclosure or next to heat-generating gear — the 63 A nameplate rating only holds up to 50 °C ambient. The interrupting capacity is what sets this variant apart: 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and still 17 kA at 690 V. Those numbers mean it can safely clear a fault on a high-capacity transformer secondary or a large UPS-backed bus without needing a current-limiting fuse upstream. The 800 V rated insulation voltage (Ui) confirms it is rated for 690 V line-to-line systems. ## Panel fit and integration The 3VA1163-6EF32-0BC0 measures 130 mm high, 76.2 mm wide, and 70 mm deep. That 70 mm depth is the dimension that matters when you are fitting it into a shallow wall-mount enclosure or a gland-plate clearance zone — it is the projection behind the panel face. The 76.2 mm width (three 25.4 mm pole pitches) matches the standard 3-pole MCCB footprint on a DIN rail or mounting plate. IP40 on the front means it is protected against tools and wires >1 mm but not against water ingress; keep it inside a panel, not on an exposed wall. It ships with an undervoltage release (UVR) and 2 auxiliary switches (HQ design). The UVR trips the breaker when control voltage drops below a threshold — standard for machinery where a loss of control power must drop the main disconnect. The two auxiliary switches give you a normally-open and normally-closed contact for status feedback to a PLC or a panel lamp. The integrated auxiliary trip is order code 3VA9608-0BB11 if you need a spare or replacement module.","metaTitle":"Siemens 3VA1163-6EF32-0BC0 SENTRON MCCB, 63 A, 220 kA at 240","metaDescription":"Siemens 3VA1163-6EF32-0BC0 SENTRON molded case circuit breaker, 3-pole, 63 A rated continuous current, 220 kA breaking capacity at 240 V.

It will not drop into the same footprint without rewiring: the 3VA1163-6EF32-0BC0 carries 220 kA at 240 V and a TM240 release, while the 3VA1112 variant is built for lower fault currents and a different trip curve. They are not direct drop-in substitutes."},{"question":"What is 3VA1163-6EF32-0BC0's listed depth (70 mm) on this component line?","answer":"The depth is 70 mm, which is the dimension behind the panel face — critical for shallow enclosure fit."},{"question":"What is 3VA1163-6EF32-0BC0's listed width (76.2 mm) on this component line?","answer":"The width is 76.2 mm, which matches the standard 3-pole MCCB footprint at 25.4 mm per pole."},{"question":"Will 3VA1163-6EF32-0BC0 drop into a panel that was specified around 3VA1112-5EF32-0CA0 without rewiring?","answer":"No — the 3VA1163-6EF32-0BC0 has a higher interrupting capacity (220 kA at 240 V vs the smaller-frame 3VA1112) and a different TM240 overcurrent release. The physical mounting footprint may be similar, but the electrical ratings and trip curve differ, so you should verify the panel's fault current rating and the load's thermal-magnetic requirements before substituting."},{"question":"What compliance documentation does Siemens provide for 3VA1163-6EF32-0BC0 (RoHS, REACH, UL, IEC)?","answer":"As a current-production SENTRON MCCB, this part carries standard Siemens compliance documentation including RoHS and REACH declarations, and it is designed to meet IEC 60947-2.
