Product Description

Product Description

Application

This T1+2 spd Class I 2 surge protective device(SPD) is suitable for 380V AC 50/60HZ TN-S and TT system. Power supply system. Designed accordingly to IEC61643-1, GB18802.1 standard. It's standard 35mm din rail installation. There is failure release mounted on the module of surge protective device. When SPD fails in breakdown for over-heat or over-current, the failure release will help electric device separate from the power supply system and give the indication signal. Green means normal, red means fault.

 

Features

1. Prewired complete unit consisting of a base part and plug-in protection modules 2. High discharge capacity due to heavy duty zinc oxide varistors/GDT 3. High reliability due to 'temperature-controlled' SPD monitoring device

4 .Din rail installation, easy to install. 5. Inside over-current, over-heat, temperature control open circuit. 6. Fast response time, low residual voltage. 7. Window color indicates working condition, green means normal, red means fault.

8. Class I II T1+2 protection degree.

 

Installation position

The cross-sectional area of ground wire should not be less than 4 mm2, and the length of total lead not more than 0.5m.

0.5MM

 

The minimum distance from any earthed conductive surface at which the SPD can be installed is 8mm.

 

Connection of remote signalling alarm: the SPD is provided with remote signalling interfaces (NC, COM and NO, normally closed), applicable for remote centralized monitoring or alarm. After the connection, check if the module is fitted in. If so, NC and COM are closed; if not, repress the module.
