Motor protection circuit breaker for panel integration
The Siemens SIRIUS 3RV1011-1JA25 is a motor protection circuit breaker rated for 10 A continuous current with a CLASS 10 trip characteristic. Rated breaking capacity reaches 50 kA at 400 V AC, sufficient for most industrial distribution panels with high fault-current potential; at 240 V AC it handles 100 kA, and at 690 V AC it still interrupts 2 kA. The 45 mm wide housing mounts via screw or snap-on onto 35 mm standard mounting rail per DIN EN 50022, fitting a standard panel footprint with 81 mm depth and 90 mm height. Spring-loaded terminals on both the main current circuit and the auxiliary/control circuit accept 2x (0.25... 2.5 mm²) solid or stranded wire (24–14 AWG), reducing wiring time compared to screw-clamp alternatives.
Key ratings and what they mean for fit
Rated operational voltage is 690 V AC, covering 400 V and 480 V systems common in European and North American industrial plants. Phase failure detection is built in — the breaker will trip if one phase is lost, preventing single-phasing damage to the motor. Power dissipation at rated current in hot operating state is 9.25 W, which should be factored into enclosure thermal calculations when grouping multiple units. Operating temperature range is -20 to +60 °C during operation, with storage and transport range of -50 to +80 °C. Shock resistance rated at 25g / 11 ms, suitable for installation on machinery with moderate vibration. Front protection class is IP20 — suitable for enclosed panels but not for washdown or outdoor exposure without additional enclosure.
Compliance and documentation
Substance prohibitance date of 01.01.2013 indicates RoHS compliance from that date forward. Surge voltage resistance rated at 6,000 V, confirming overvoltage category III coordination for industrial control panels.
