Apparatus Padlocking and sealing Each front cover can be padlocked with up to 2 padlocks pr phase, or up to 3 padlocks pr phase by using the padlock hasp. The ZLBM/ZHBM 3–pole, can also be padlocked with up to 2 padlocks in open position. Sealing can be done in the same way as done with the padlocks. Park position The front covers of the ZLBM/ZHBM 1-pole variants can be placed in park position with the possibility to be padlocked. The padlock hasp can also be used in this position when up to 3 padlocks pr phase is requested.

Accessories Electronic Fuse Monitoring (EFM) The ZLBM/ZHBM electronic fuse monitoring (EFM) gives an alarm if any fault conditions, if 1, 2, and/or 3 fuses are blown. • An internal output relay (1NC + 1NO) ensures a signal for a remote fuse blown alarm. The EFM unit is self supplied - no additional power supply is required. Park position: The EFM unit can be completely disconnected from the live fuse contacts by pulling the unit out from the EFM house. This is an advantage when doing a dielectric insulation test of the whole installation in a switchboard. The green LED in the front panel...

Accessories Electronic Fuse Monitoring (EFM) Note • The EFM requires power supply from the busbar side phase L2 and L3. • If there is a loss of the power supply voltage after a blown fuse alarm is created, there must be a minimum period of 10 seconds before the power supply can be connected again. This is to ensure correct alarm positioning of the EFM relay. Q1= Fuse switch disconnector K1= Fuse monitor (EFM) V1= Fuses ok V2= Fuse(s) blown X1= Multiplug terminals Fuse status 1.
