Product name: HCT3730 circuit breaker simulator
Category: Relay protection comprehensive test series

Detailed introduction

Product introduction

HCT3730 circuit breaker simulator is mainly used for the whole group test of relay protection devices, and replaces the real high-voltage circuit breaker in the test of standby power supply automatic device and other projects. Cooperating with the microcomputer relay protection tester system for on-site debugging, it can accurately simulate the action behavior of the circuit breaker. The action time and DC resistance are adjustable, which reduces the number of switch actions of the circuit breaker during the protection debugging. It is an indispensable and important equipment for the microcomputer relay protection test system.
