Product Description

●Model and Meaning ●Introduction

GFH1-125Z Changeover switch is a critical electrical device specifically engineered for small and medium-sized power distribution systems. Its core function involves reliable and safe switching between two independent power sources (primary and backup), ensuring that when the main power supply fails (such as during power outages or voltage anomalies), the load circuit can be manually switched to the backup power source. This guarantees uninterrupted and reliable power supply continuity.
GFH1-125Z Changeover switch This device is designed for AC circuits operating at 50Hz with voltages up to 380V and DC circuits up to 220V, featuring rated currents ranging from 16A to 125A. Its dual-break contact structure enables multi-circuit switching through a rotating handle, delivering compact design, intuitive operation, and high reliability. Widely used in machine tool electrical control systems, phase-changing applications for measuring instruments, and small-capacity motor control scenarios.
Product complies with standard: IEC/EN/BS EN60947-3。
