4-way surge current relay, also for central and group control. With 4 independant contacts. Standby loss only 0.03 to 0.4 watts. To do this, simply connect the N conductor to the clamp (N) and the external conductors to 1(L), 3(L) or 5(L). This results in an additional standby consumption of only 0.1 watts. If the contact is used to control switching devices that do not switch themselves at zero crossing, (N) should not be connected, as the additional closing delay otherwise causes the opposite. Local universal control voltage 8..230V UC. With additional universal voltage control inputs centrally on and off for 8..230V UC, electrically isolated from the local control inputs. With additional group control inputs on and off for 8..230V UC. Same potential as local control inputs. Groups of these surge current switches can be controlled separately in a central control system via the group control inputs. Supply voltage as the local control voltage. The latest hybrid technology combines the advantages of wear-free electronic control with the high power of special relays. By using bistable relays, there is no coil power loss or heating thereby even when the relay is switched on. After installation, wait for the automatic short synchronization before connecting switched loads to the mains. Central commands always have priority; the local control inputs are disabled during the central command. If the supply voltage fails, it is switched off in a defined way.
