Product Description

●Model and Meaning ●Introduction

The GFB1-125 series plastic case circuit breakers are primarily used in power distribution lines (terminal distribution lines in commercial office buildings, residential buildings, and general industrial applications),new energy, and transportation, with a rated voltage of 230V to 400V AC (50/60Hz) and a rated current of63A to 125A. They provide overload and short-circuit protection for these lines. Under normal circumstances,these lines can be switched infrequently. These miniature circuit breakers feature unique curves (10In)and varying breaking capacities（6kA) to ensure effective load protection。
The GFB1-125 series plastic case circuit breakers are installed using a guide rail, providing greater adaptability. Single-stage products can be quickly replaced after the busbar is installed. This series of circuit breakers is designed to comply with the IEC/EN , greatly improving the safety of the electrical system。
Product complies with standard: IEC/EN/BS EN60898-1。
