How to handle electric motors in a safe way? We are surrounded by electric motors and fans. In our society, much attention is paid to the safety of electric circuits. Electric motors in particular require extra protection, since they usually go together with higher currents and moving mechanical parts. Switch disconnectors can be applied as safe maintenance and repair switches or as enclosed main switches for individual electrical loads. Motor protection circuit breakers provide short-circuit, phase-loss and thermal overload protection.
Switch disconnectors, padlockable OFF position
How to disable the main supply during maintenance activities? EME5 switch disconnectors are manually operated switching devices with a direct link between manual operating element and the contacts. The contacts are positively opened on de-energization. EME5 switch disconnectors are particularly suitable as safe maintenance and repair switches or as enclosed main switches for individual electrical loads. Padlocks can be connected in the OFF position. This provides a vital safety function: the no-voltage state is visible and switch on is impossible. EME5 switch disconnectors are also suited for direct switching of motors. In applications where frequent switch on and off operations are required, the high switching capacity guarantees reliability.
A motor protection circuit breaker is a device integrating Low voltage circuit breakers and Thermal Overload Relays functions. This device is capable of protecting the motor branch circuits against overload, phase-loss, and short-circuit on its own. It enables even more secure wiring and motor protection.
