Interrupting capacity is 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V — that covers high-fault utility feeds and transformer secondaries where SCCR headroom matters. The base switch is order code 3VA11635EF320AA0. Dimensions: 130 mm height, 76.2 mm width, 70 mm depth — fits standard SENTRON 3VA panel cutouts and busbar arrangements.","metaTitle":"3VA1163-5EF32-0JH0 SENTRON MCCB, 63 A, 3-pole, line protecti","metaDescription":"Siemens SENTRON 3VA1163-5EF32-0JH0 molded case circuit breaker, 63 A at 40 °C, 3-pole, line protection.
