Circuit breaker for starter combinations — SIRIUS 3RV6311-0JC10
The Siemens SIRIUS 3RV6311-0JC10 is a 3-pole circuit breaker in size S00, designed specifically for starter combinations. The magnetic short-circuit trip provides the fast interruption needed to protect downstream contactors and overload relays in a motor starter assembly.
Any mounting position is permitted. The S00 frame width is 45 mm, depth 96 mm, height 97 mm — fits standard panel layouts. Screw-type terminals accept 2x (0.75 to 2.5 mm²) solid/stranded or 2x 4 mm², with a tightening torque of 0.8 to 1.2 N·m.
Rated values and operating conditions
Operating frequency at AC-3 is 15 operations per hour maximum. Rated frequency is 50 to 60 Hz. Surge voltage resistance rated at 6 kV. Relative humidity during operation: 10 to 95%. Installation altitude up to 2000 m above sea level. Shock resistance per IEC 60068-2-27: 25 g for 11 ms.
