Siemens Sirius Innovation 690 V ac/dc Motor Protection Circuit Breaker - 3P Channels, 50 A, 50 kA

Circuit Breakers 3 Pole - 3RV10 & 3RV13 Range

Siemens 3RV10 and 3RV13 moulded case circuit breakers are compact, current limiting motor starter protectors which can be used in motor feeders for special voltages of 440V, 480V, 550V and 690V. They are used for switching and protecting induction motors and other loads with rated currents up to 800A.
For motor protection the overload and short-circuit releases are designed for optimized protection and direct starting of induction squirrel cage motors. The motor starter protectors have an electronic release which not only provides short circuit and overload protection but is also sensitive to phase failure and phase unbalance and offers protection in the event of rotor blockage.
For starter combinations these moulded case motor starter protectors are used for short circuit protection in combinations of circuit breaker, motor contactor and overload relay. They are equipped with a purely magnetic release (up to 32A) or a electronic release (100A to 800A).

Siemens SIRIUS Cage Clamp Technology

As an alternative to screw connections a large number of Siemens low voltage components are also available with cage clamp connections.,Solid, stranded and finely stranded conductors, with or without end sleeves, can be connected, where two conductors can be clamped independent of one another at each terminal.,Inserting a flat bladed screwdriver opens the terminal; the conductor is then introduced and securely clamped following the removal of the screwdriver. The chromium-nickel spring steel of the cage clamp terminal guarantees corrosion resistant contact of the conductors.
