TSTLP®/TS-BC25RM Type 1+2 Lightning Current & Surge Arrester
TS-BC25RM series Type 1 lightning current & surge arrester, designed according to IEC / EN 61643-11 & GB 18802.11 is for installation at LPZ 0A -2 or higher, protecting low voltage equipment against lightning and surge damages. Applied SPD Modular in Class I+II (Class B+C) for various power supply system.
Similar & Related Power Supply Surge Protectors
♦ MAIN CHARACTER
1. 10/350, 8/20ps varistors
2. Consist of varistor and thermal disconnection device
3. High discharge capacity, quick response, pluggable
4. Double thermal disconnection devices, providing more reliable protection
5. Multifunctional connection for conductors and busbars
6. Green window will change to red when fault and also provide remote alarm control at the same time
INSTALLATION INSTRUCTION
According to lightning protection zones concept, for installation at LPZ 0A -2 or higher. It is usually installed in floor distribution-box or ClassⅠmain distribution-box
Fuse must be installed at the upstream of the SPD or the surge protector to make sure that protected system has double protection. The value of the fuse used in a SPD system 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 be able to disconnect when overloaded or short-circuited.
Take 1 & 2 into consideration, the fuse should be as large as possible to allow the maximum surge discharge of SPD.
INSTALLATION STEPS
1) Check the product for integrity of the package; make sure the product window indicates green.
2) Mount the SPD on 35 mm DIN rail.
3) Connect conductors, the cross-sectional area of cable must be larger than 16mm2 . The withstand voltage value of cable is not smaller than AC500V; ensure wiring reliable.
4) If 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) Remote Contact: When the Green window display RED, 1 & 2 are connected; And the extra light will be on if the both terminals are connected with light.
6) After above, switch on the power supply and turn on the circuit breaker,if the SPD’s window does not appear red, this indicates the unit is operating normally.
Regularly inspect the operating status, especially after lightning. Once the fuse upstream break, or the SPD’s fault appear, electrician should check/replace the SPD.
