Latching Relays

Description

  • For the control of lighting circuits in residential buildings, small industry buildings and commercial buildings.
  • Latching relays operates when impulsed by a signal voltage.
    The impulse can be provided via a pushbutton or switch. The first impulse sets the relay into its set (opposite) state, the next impulse returns it to its reset (original) state.

The latching relays are built to add on optionally the following auxiliaries :
– an auxiliary for centralised ON/OFF control EPN 050
– an auxiliary contact for remote signalling EPN 051
– an auxiliary for multi levelled centralised control EPN 052
– an auxiliary for control by maintained contact EPN 053

Connection capacity

  • 10mm2 rigid cables
  • 6mm2 flexible cables

Conform to standard

IEC60669-1 and IEC60669-2-7

Latching Relays Auxiliaries

  • Auxiliaries for centralised control The EPN 050 allows the centralised control of several light sources which can be turned on or off simultaneously.
  • The separate switching by pushing the pushbuttons, which are connected with the latching relay, remains possible.
  • The EPN 052 allows an overall central control of individual central on/off EPN 050

Auxiliary contact

  • A remote signalling can be realised with the auxiliary contact EPN 051.
  • Auxiliary for control by maintained contact
  • When control devices with permanent impulse are externally driven, e.g. time switches or limit switches, an impulse control directly to the latching relay’s coil is possible with the auxiliary contact EPN 053.
  • Connection latching relay + auxiliary
  • Several auxiliaries can be combined with the latching relay.
