What’s the use of bipolar, bipolar alternating, double alternating and three-pole switches?
Bipolar switch is intended for circuits of the customers, where the simultaneous disconnection of the phase and neutral conductor is required. The most frequent application is with circuits of single-phase motors. Other areas of application: – customers for which it is important to disconnect neutral conductor as well (facilities or buildings not having the protection for voltage of touch, facilities with grounded neutral protection, bulbs (lights) with metal design protection). – combination with receptacle to higher rated currents. Bipolar alternating switch has embodied in itself the functions of bipolar and alternating switch. It means that this switch can disconnect simultaneously neutral and phase conductor (function of bipolar switch) from two different locations (function of alternating switch). Double alternating switch has embodied the function of two alternating switches in order to create the possibility of switching on and off two groups of the customers from two different
