Eaton Motor Protective Circuit Breaker - PKZM0 Eaton's reliable and robust motor protection circuit breakers are the perfect solution for protecting your motors from faults such as an overload of high voltages, short circuits or relay shutdowns. Down-time of machinery can be detrimental to a business and its operations, Eaton's PKZM0 range of motor protection circuit breakers has been created and designed to act as an intermediary between your devices, protecting vital equipment in the event of unforeseen incidents. This reduces the amount of downtime of machinery to enable operations to continue running smoothly. Features & Benefits DIN-rail mounting Forms part of the xStart family of control gear products Typical moto protection accessories – Shunt release 492-1709 & 492-1715 , lockable rotary handle 244-0113 Rated operating voltage 690Vac How do I select the right Motor Protection Circuit Breaker? MPCBs are more critical now than ever. Most infrastructures now rely on a motor behind the scenes to power critical uninterruptible systems such as heating, ventilation and cooling. These systems are vital in ensuring business continues as usual, therefore must be protected against overcurrent's, thermal overloads and similar problems. To select the right MPCB, consider the systems you and your business rely upon. Checking the features and benefits of each MPCB will prove invaluable when deciding what critical infrastructure you wish to protect.

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). High short circuit breaking capacity in the feeder Optimum usability in load feeders for the special voltages 440V, 480V, 550V and 690V Compact design The releases are available both in purely magnetic (up to 32 A) and in solid-state versions (100A to 800A) Note Most of the Sirius 3R components are available with cage clamp connections. For the size S00 products, with rating up to 5.5kW, this includes both power and control circuit connections. For higher rated products cage clamp is available for the control wiring connections such as operating coils and auxiliary contacts.
