Details
switch-disconnectors, 63 A, 4 NO, with EMERGENCY SHUT-OFF function and remote actuator
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. The FANA variant DHS 4 allows devices to be switched on and off remotely. Control elements, such as push-buttons for disconnecting the switch-disconnector in emergency situations, can also be connected via the compact, factory-installed additional module. It is even possible to parallel wire multiple DHS 4s. The LED integrated in the switch-disconnector not only indicates tripping by a control element but also any possible wire breakage. In this state, it is not possible to reclose the switch-disconnector.
With emergency switching off 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
quick fastening to mounting rail , supply from top , any installation position
Particularly suitable for facilities such as training rooms and classrooms. The remote operator with emergency switching off function enables the power supply to be switched on again, e.g. using a key switch, without having to leave the room and/or open the electrical distribution board.
According to EN 60947-3, switch-disconnectors combine the function of a load-break switch that can switch on, conduct 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 provides FELV (functional extra-low voltage) to the emergency shut-off circuit. For this reason, the emergency shut-off circuit must be rated for a voltage of 230 VAC. The DHS 4 can also be locked with the light disc. The remote actuator must be supplied externally with 24 VDC.
