It's rated CLASS 10 trip class, meaning it will trip within 10 seconds at 7.2× the thermal setting — fast enough to protect standard induction motors during a locked-rotor event without nuisance tripping on normal starts. ## Breaking capacity and voltage range Rated operating voltage spans 20 to 690 V AC, covering low-voltage motor circuits from control transformers up to 690 V line supplies. The 55 mm width and 149 mm depth fit standard motor starter cubbies; the M6 main contact screws accept 2x (0.5 to 2.5 mm²) conductors.","metaTitle":"Siemens 3RV2031-4DA15 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens SIRIUS 3RV2031-4DA15 motor protection circuit breaker.
