Ground fault detection is not included, so if you need that, you add an external module. The 55 mm width (3.5 module spaces) is standard for this current class — plan for that footprint in your panel layout. At 240 V, no side clearance is needed. Conductor termination is screw-type, accepting 2x (1 to 35 mm²) solid or stranded, or 1x (1 to 50 mm²). Main contact terminals are M6. Any mounting position is allowed, which simplifies panel layout. ## Ratings and selection The 3RV2032-4RA10 is rated for motor protection with a Trip Class 10 — it trips within 10 seconds at 7.2× the thermal setting, which is the standard for standard-duty induction motors (pumps, fans, compressors). The continuous current rating is 77 A at 480 V and 600 V, so it covers motors up to 60 hp at 460/480 V and 75 hp at 575/600 V. The rated operational voltage range is 20 to 690 V AC. Maximum switching frequency in AC-3 duty is 15 operations per hour — fine for a motor start, not for a jogging application.","metaTitle":"Siemens 3RV2032-4RA10 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV2032-4RA10 SIRIUS motor protection circuit breaker, 77 A at 480 V, Trip Class 10, 100 kA interrupting at 240 V.
