Load disconnectors or main switches separate electrical consumers or system parts completely and on all poles from the electrical supply. They also switch under load or overload. They are used for shutdown for maintenance work and for system protection. The devices of the DHS 4 series are load disconnectors or main switches in a four-pole design in which the N contact is switched on in a leading manner and switched off in a lagging manner. Their design means they fit perfectly into the look of the DFS residual current circuit breakers. DHS with EMERGENCY STOP function enable the connection of an EMERGENCY STOP device, such as: B. Button. An integrated LED signals activation by an actuation element or by a wire break. Reconnection will be prevented until the problem is rectified. Properties - with EMERGENCY STOP function for triggering or switching off using actuating elements. Monitoring of the EMERGENCY STOP function for wire breaks and display by an LED. In the event of a power failure, the EMERGENCY STOP function does not trigger, high short-circuit strength and high switching capacity, double-sided double-decker terminals for large conductor cross-sections and busbars, switching position indicator. Mounting type - quick attachment to mounting rail, feed from above. Any installation position. Areas of application - particularly suitable for use in main distributions in extensive power supplies, e.g. B. for campsites, marinas, allotment colonies, showplaces, etc. Notes - According to EN 60947-3, load disconnectors combine the function of a load switch, which can switch on, carry and switch off a current (including a specified operational overload) under operating conditions, as well as the function of a disconnector. which ensures safe separation when switched off due to sufficient contact distance. The DHS 4 supplies a FELV voltage for the emergency stop circuit. For this reason, the emergency stop circuit must be rated for a voltage of 230 VAC.
