Product Description

Product Description

Summary

BT P BCM 275 RM/3+N is for installation at LPZ 0_A-2 or higher. protect low voltage devices from surge damages, Specially designed for TT/TN-S system ("3+1" circuit). Applied in SPD Class I+II (Class B+C) for three-phase system of lightning current surge protection. Designed according to lEC 61643-11; EN 61643-11: GB/T 18802.11.

Main character

Installation instruction

Installation steps

According to lightning protection zones concept, forinstallation at LPZ 0,-2 or higher. This surge protectivedevice is usually installed in distribution-box or feeder busof UPS, protecting devices or equipment downstream.Fuse must be installed at the upstream of the SPD or thelightning arrester to make sure that the protected systemhas double protection. The value of the fuse used in a SPDsystem should be conformed to:

1. The value of FUSE should not be larger than the max.withstand capacity of the SPD's backup fuse value.

2. Under the status of the max. current in the power supply& close loop circuit available current, the fuse should beable to disconnect when overoaded or short-circuited.

3.Take 1 & 2 into consideration, the fuse should be as largeas possible to allow the maximum surge discharge of SPD.

1. Check the product for integrity of the package; makesure the product window indicate green.

2. Mount the SPD on the 35mm DlN rail.

3. Connect conductors, the cross-sectional area of cablemust be larger than 6mm sq. The withstand voltage value ofcable is not smaller than AC500V; ensure wiring reliable.

4. lf need remote alarm, it should be connected signal lines to remote signal terminal 1 and 2, or 2 and 3 (When normal,1 and 2 open, 2 and 3 close; when fault, the state is reversed).

5. After above, switch on the power supply and turn on thecircuit breaker, if the SPD's window indicates green, this indicates the unit is operating normally.

Regularly inspect the operating status, especially after lightning. Once the fuse upstream breaks, or the SPD's window indicates red, electrician should check/replace the SPD.
