switch-disconnectors, 63 A, 4 NO, with emergency shut-off function

Switch-disconnectors and main switches disconnect electrical consumers or system parts completely from the electrical supply at all terminals. They also switch under load or in the event of overload. They are used to switch off electrical consumers for maintenance work and to protect the system. Devices in the DHS 4 family are load isolators and main switches with a four-pole design, for which the N-contact is switched on in advanced mode and switched off in lagging mode. Their design makes them excellent for integration in the optics of the DFS residual current circuit-breakers. DHS with emergency switching off function enable connection of an emergency stop device, e.g. push-button. An integrated LED indicates tripping caused by a control element or wire breakage. Reclosing is prevented until the fault is rectified.

With emergency switching ogg function for tripping or disconnection by means of control elements, Monitoring of emergency switching off function for wire breakage and signalling by LED, In the event of a power failure, the EMERGENCY OFF function does not trigger, High short-circuit resistance and high switching capacity, Double-sided two-tier terminals for large conductor cross-section and busbars, Switch position indicator

quick fastening to mounting rail , supply from top , any installation position

especially suitable for use in main distribution boards in power supplies to large areas, such as campsites, marinas, allotment gardens and showrooms.

According to EN 60947-3, switch-disconnectors combine the function of a load-break switch that 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 that ensures safe disconnection by means of a sufficient contact gap when switched off. The DHS 4 supplies an FELV voltage for the emergency switching off circuit. For this reason, the emergency switching off circuit must be rated for a voltage of 230 VAC.
