Doepke DHS4-125NA

Load disconnectors or main switches completely and all-pole disconnect electrical consumers or parts of installations from the electrical supply. They can also switch under load or overload. They are used for shutdown during maintenance work and for system protection. The devices of the DHS series are load disconnectors or main switches in a four-pole design, where the neutral contact is switched on in advance and switched off in delay. Due to their design, they integrate excellently with the appearance of the residual current circuit breakers DFS. DHS with emergency stop function allow the connection of an emergency stop device, such as a button. An integrated LED indicates activation by an operating element or by wire break. Reconnection is prevented until the issue is resolved.

Features: with emergency stop function for activation or shutdown via operating elements, monitoring of the emergency stop function for wire break and indication via an LED, in case of a power failure the emergency stop function does not lead to activation, high short-circuit resistance and high switching capacity, double-decker terminals on both sides for large conductor cross-sections and busbars, switching position indication, mounting type: quick fastening on mounting rail, top feeding, installation position arbitrary.

Areas of application: particularly suitable for use in main distributions in extensive power supplies, e.g., for campsites, marinas, allotment gardens, fairground sites, 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 disconnect switch, which ensures safe disconnection through sufficient contact distance in the switched-off state. The DHS provides a FELV voltage for the emergency stop circuit. For this reason, the emergency stop circuit must be rated for a voltage of 230 VAC. DHS 4-125 NA.
