Width is 45 mm. Depth is 97 mm, height 119 mm. Backup fuse coordination: at 400 V, the upstream gG fuse must be rated 63 A; at 500 V and 690 V, 50 A. That limits the let-through energy so the breaker's internal contacts survive a bolted fault. Breaking capacity at 690 V AC is 2 kA or 4 kA depending on the test condition — the lower figure is the conservative one for coordination studies. Motor horsepower ratings across common line voltages: 1.5 hp at 110/120 V, 7.5 hp at 200/208 V and 220/230 V, 3 hp at 230 V, 15 hp at 460/480 V, 20 hp at 575/600 V. At 480 V and 600 V the current rating is 22 A. Voltage range is 20 … 690 V. Switching frequency: 15 operations per hour maximum under AC-3 and AC-3e duty. Clearance requirements: 50 mm upwards and downwards, 30 mm at the sides — that's for arc flash venting and thermal dissipation. Mount in any orientation, but keep those gaps clear.","metaTitle":"Siemens 3RV2023-4CA20 SIRIUS Motor Circuit Breaker, CLASS 10","metaDescription":"Siemens 3RV2023-4CA20 SIRIUS motor protection circuit breaker, CLASS 10 trip, 45mm wide, screw/DIN rail mount.
