Plastic case circuit breaker

概述 /Overview

HCM1 系列塑料外壳式断路器 ( 以下简称断路器 )，是本公司采用国际先进设计、制造技术研制、开发的新型断路器之一。其额定绝缘电压为 1000V，适用
于交流 50Hz，额定工作电压 690V 及以下，（JFM1-63 为 400V), 额定工作电流至 800A 的电路中作不频繁转换及电动机不频繁起动之用。断路器具有过载、
短路和欠电压保护功能，能保护线路和电源设备不受损坏。
HCM1 series plastic case circuit breaker (hereinafter referred to as circuit breaker) is one of the new circuit breakers developed and developed
by the company using international advanced design and manufacturing technology. Its rated insulation voltage is 1000V, suitable for AC 50Hz,
rated working voltage 690V and below, (JFM1-63 is 400V), the rated working current is up to 800A for infrequent conversion and the motor is not
frequently started. The circuit breaker has overload, short circuit and under voltage protection to protect the line and power equipment from
damage.
