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.

Apparatus Properties Voltage measurement The front windows can be slided up to give access for voltage measuserement at the fuse contacts Optimized ventilation ribs The design of the ZLBM/ZHBM body has been given priority to give the most optimized ventilation of the apparatus. An integrated ventilation channel at the side of the body will also support the air ventilation upwards between the apparatuses when they are installed side by side. Circuit labels The integrated front terminal shroud has a dedicated area for circuit labels. This integrated front terminal shroud is interlocked when...

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.
