YJ1-C40 surge protector

Product Introduction

This series of surge protectors is suitable for TT, IT, TN-S, N-C-S and other power supply systems with AC 50Hz, 380V and below, and can be used as equipotential connections at the interface of LPZ1, LP22 and LP23 zones. Its design basis complies with IEC61643-1, GB18802.1， The shell is designed to be installed on a 35mm electrical rail, and the product has a built-in failure release device. When the surge protector fails due to overcurrent, overheating, or breakdown, the failure release device can automatically disconnect it from the power grid, and the visual alarm indicator window changes from green (normal) to red (fault).

application

The YJ1 series module is used for equipotential connection during lightning strikes and is installed at the junction of LPZOB zone, LPZ1 zone, and LPZ2 zone. It is usually installed in floor distribution boxes, computer centers, telecommunications rooms, elevator control rooms, frequency conversion equipment control rooms, hospital operating rooms, monitoring rooms, and distribution boxes in places where electronic medical equipment is installed. SPD should be installed in residential distribution boxes for dispersed small villas.

Product design and ordering instructions: Users should clearly indicate the product model and quantity when designing and ordering products.
