The AC-3 operational current at 400 V is also 630 A — that's the motor-switching duty, making this breaker a direct fit for a 630 A motor branch circuit without oversizing. The electronic short-circuit trip gives adjustable magnetic pickup, which helps coordinate with downstream contactors and avoid nuisance trips on inrush. The 15 operations per hour maximum at AC-3 is a duty-cycle limit — not a continuous-switching device; it's meant for occasional motor starts, not frequent cycling. The 20–690 V rated voltage range covers low-voltage industrial systems worldwide — 208 V, 240 V, 400 V, 480 V, 600 V, and 690 V all fall inside. The surge voltage resistance of 8 000 V (impulse withstand) means it can handle switching transients on a 690 V line without internal flashover. The IP20 front protection is typical for panel-mounted breakers; the enclosure provides the real ingress protection. Screw fixing to a mounting plate or backpanel — no DIN rail for this frame size. The 140 mm width, 205 mm height, and 103.5 mm depth fit a standard motor control center bucket or a standalone enclosure. Zero clearance required at the back and sides simplifies panel layout; you can butt it against adjacent devices without derating for heat buildup. Any mounting position is allowed, which helps in tight retrofit situations where the panel orientation is fixed. The part carries RoHS substance prohibitance dated 01/08/2008, compliant with the EU directive. The finger-safe touch protection (IP20 front) meets IEC 60529 for operator safety in open panels. No ground fault or phase failure detection built in — that's handled by the upstream protection or a separate relay. The electronic trip design is inherently more precise than thermal-magnetic for coordination studies.","metaTitle":"3RV1373-7JN10 SIRIUS MCCB, 630 A, 120 kA @ 400 V","metaDescription":"Siemens SIRIUS 3RV1373-7JN10 molded-case circuit breaker, 630 A continuous, 120 kA breaking at 400 V AC, 200 kW motor rating.
