Protective Devices
PBR Main Protective Device
ATTENTION:
The main protective device does not replace a residual current device (RCD).
For protection against residual current or additional protection you still need
to install an RCD even if you use a main protective device.
The objective of the PBR main protective device is preventive fire protection
only.
• Tripping current identification (I
Δn
) is independent of the line voltage
• Integrated overload protection
• Contour and busbar compatible with other devices of the P series
• Double-comfort terminal lift/open-mouthed at top and bottom
• Free selection of the busbar arrangement at top and bottom
• Free terminal space despite the fitted busbar
• Universal Z-NHK tripping signal switch can be retro-fitted
• Auxiliary Z-HK switch can be retro-fitted
• Contact position indicator red - green
• Suitable for use with commercially available standard fluorescent lamps
with or without electronic ballast
• The function of the switch is independent of its position
• Mains connection on any side
• The 4-pole switch cannot be used as a 3-pole switch
• The 4-pole switch can also be used as a 2-pole switch
In this case use terminals 1-2 and N-N (+ wire bridge, see instructions).
• The test button “T” needs to be activated once a year. This fact and respon-
sibility needs to be communicated to the system operator in a provable
manner.
• Due to their tripping characteristics the main protective devices feature full
selectivity with regard to downstream electromagnetic quick tripping relays
of MCBs according to EN 60898-1 and of “general” and “S” types of RCD
protective devices according to EN 61008-1.
Main protective devices are particularly important as fire protection in
3L+PEN ~400/230 V networks (TN-systems).
Main protective devices are particularly important as back-up protection
against electrical shocks in 3L+N ~400/230 V networks (TT-systems)
