Scope of application
TLYS1-C series surge protective devices are suitable in AC 50Hz/60Hz, 230V/400V and the following TT, IT, TN-S, TN-C, TN-C-S power supply system, etc as the equipotential connection. Its design conforms to the IEC61643-1, GB18802.1-2002, GB50057-94
Requirements, witch is used in the protecting electrical device of low voltage power users, and prevents form surge current caused by atmospheric discharges (such as lightning) or operating over-voltage. It is equipped with heavy-duty zinc oxide
Varistors as a single voltage limiting device.
Installation guidance and electrical connection TLYS1-C series protector may be close enough to protect applications installed on the client device on the need to protect the uplink side (pull cord connected immediately downstream line), connecting the outer conductor (L1, L2, L3) or neutral (N) and the client device grounding. Installed in LPZOA / OB area and LPZ1 area or LPZ1 area at the junction with LPZ2, usually installed in the inlet line low-voltage main distribution cabinet.
Main specification and technical parameter is shown in Table 1
We also produce many various of surge protectors.
