Breaking capacity is the headline number for an MCCB: this unit delivers 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V. The overcurrent release is a TM240 — thermal-magnetic, fixed at 240 A frame rating, adjusted for the 63 A continuous current. No undervoltage release, no ground fault monitoring, no communication module, and no voltage trigger are fitted on this variant. The MCCB measures 130 mm high, 76.2 mm wide, and 70 mm deep — a 3-pole footprint that fits standard SENTRON panel cutouts. For switching applications that cycle daily, this is a long-life device; for frequent on-off duty under load, consider a contactor ahead of the MCCB.","metaTitle":"Siemens 3VA1163-3EF36-0AD0 SENTRON MCCB, 63 A, 3-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1163-3EF36-0AD0 molded case circuit breaker, 63 A rated, 3-pole, 75.6 kA at 240 V.
