What this MCCB carries
The Siemens 3RV1383-7KN10 is a SIRIUS molded-case circuit breaker (MCCB) rated for 800 A continuous current, designed specifically for starter combinations in motor control centers. Its interrupting capacity hits 100 kA at 240 V and 400 V AC, drops to 65 kA at 500 V, and holds at 30 kA at 690 V — meaning this breaker clears high-fault scenarios without upstream coordination issues in most industrial distributions. The electronic short-circuit trip gives you adjustable curves for motor starting inrush, so you're not nuisance-tripping on a 400 kW induction motor across the line.
Mounting and integration
Screw fixing to the panel backplate, any mounting position. Dimensions: 268 mm tall, 210 mm wide, 103.5 mm deep — zero clearance needed at the back or sides for heat dissipation. IP20 on the front, finger-safe touch protection. Main and control circuit terminals are screw-type; the design accepts auxiliary switch add-ons (not included as standard — zero NO, NC, or CO contacts shipped). Rated for 20 to 690 V AC-3 duty, max 15 operations per hour. Surge withstand at 8 kV. Ambient operating range -25 to +50 °C; storage and transport -40 to +70 °C. Shock rated 12g for 11 ms.
Lifecycle and sourcing reality
Substance prohibitance date of 01/08/2008 aligns with RoHS compliance requirements. No ground-fault or phase-failure detection built in — that's handled upstream or by the motor starter itself.
