Doepke 09900004 Main switch for rail mounting 1 pc(s)

Load separation or Main switches completely separate electrical loads or system components from the electrical supply. They also switch under load or overload. They are used to shut down maintenance work and plant protection. The devices of the series DHS 4 are protective against load and/or Main switch in four-pole design, in which the N-contact is switched on in advance and switched off afterwards. Because of their design they insert themselves excellently in the look of the ground fault circuit interrupter DFS. The DHS can be supplied by an auxiliary or Fault signal switches can be extended, WAS enables the display and further processing of the switching state. Properties: High short circuit strength and high switching capacity; double sided double level terminals for large cross section of cable and busbars; indication of switch position; Mounting type: Rapid mounting on rails; mounting position arbitrarily; applications: Particularly suitable for use in main distributions in widely expanded power supplies e.g. for camping sites, marinas, small garden colonies, exhibition sites etc.; Notes: In accordance with EN 60947-3, circuit breakers, circuit breakers and switch disconnectors are used in practice as main switches. The circuit breaker must switch on, conduct, and switch off currents under operating conditions in the circuit (including a defined operational overload). No separation function is required when the switch is switched off. A circuit breaker is therefore not suitable for a safe separation in the sense of the international installation regulations. Disconnect switches must meet the appropriate requirements for a separation function when the switch is switched off, but only currents of negligible size need to be switched in the case of operation. The combination of both versions is the switch disconnectors. Which combines both properties in itself and can thus be used universally for the safe activation of electrical systems.
