Its headline breaking capacity of 220 kA at 240 V (154 kA at 415 V, 121 kA at 440 V, 17 kA at 690 V) means it can safely interrupt fault currents up to those levels without cascading upstream — a key spec for high-fault panels where upstream breaker coordination is tight. This is a line protection version (no ground fault monitoring, no phase failure detection, no communication function), designed for straightforward overcurrent and short-circuit protection of feeders and downstream loads. The 63 A rating holds flat from 40 °C through 50 °C, then derates linearly to 56.7 A at 70 °C — a gentle curve that gives headroom in warm enclosures without oversizing the frame. Latching endurance is 15,000 cycles. No auxiliary contacts are fitted as standard; the auxiliary trip is a separate order (3VA9608-0BB24) if remote signaling is needed. Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a compact 3-pole frame that fits standard panel cutouts for the 3VA platform. The undervoltage release (UVR) is factory-fitted; verify coil voltage compatibility with your control circuit before installation.","metaTitle":"Siemens 3VA1163-6EF36-0CA0 SENTRON MCCB, 63 A, 220 kA at 240","metaDescription":"Siemens 3VA1163-6EF36-0CA0 SENTRON molded case circuit breaker, 63 A rated current, 220 kA breaking capacity at 240 V, 3-pole, line protection, undervoltage release.
