YJ1-B60 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 used as the first level power surge protection product for power supply systems and has high surge current collection and discharge capacity, with a maximum discharge current of 160kA (8/20 μ s). It is installed as the first level power surge protection for equipment systems in areas with high lightning risk.

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