Siemens Motor Protection Circuit Breaker Selection Guide

Siemens provides different types of residential circuit breakers based on our customers needs and the requirements of.

Siemens motor protection circuit breaker selection guide.

In the event of a short circuit current 13 times the rated current the short circuit releases isolate the faulty load feeder from the power supply within only a few milliseconds. 0 4 25 a 3vs16. Equipment protection critical equipment is protected via fuse or circuit breaker plugs. 6 52 a the characteristic curves of these motor starter protectors are specially laid out for the overload and short circuit protection of motors.

Standard for safety for molded case circuit breakers molded case switches and circuit breaker enclosures. The 3vs13 3vs16 motor starter protectors are suitable for use in any climate. This type of the wl low voltage insulated case circuit breakers are generally intended to provide service entrance feeder and branch circuit protection in accordance with ul csa 489. Low voltage interface the removable cover of the sion 3ae1 and 3ae5 vacuum circuit breakers enables easy access to the low voltage inter face.

Residential circuit breakers are designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. Industrial controls protection devices sirius 3rv motor starter protectors manual 08 2018 a5e03656507320a rs af 007 introduction 1 standards 2. Due to their proximity the plugs provide a localized method of protection and disconnection. If the frequency is reduced the voltage must be reduced or the magnetic flux will be too high and the motor will saturate.

Sirius 3rv2 motor starter protectors reliably intervene in three different cases. Motor starter protectors for motor protection 3vs13. Manufacturing tolerance of the short circuit tripping function allows a miniature circuit breaker to be selected according to the application. Siemens industry catalog automation technology industrial controls protection equipment motor starter protectors circuit breakers.

System pro m compact circuit breakers offer up to five trip curves. Therefore in order to control the motor speed it is necessary to control the frequency of the supply. Space space in critical power data center facilities is at a premium. Xj l hd busway requires less space than conventional power distribution methods such as cable.

Hence the speed of the motor depends on the applied frequency as well as the winding arrangement and a little on the load.
