HBM1L 带剩余电流保护塑料外壳式断路器
HBCE
Plastic case circuit breaker

概述 Overview
HBM1L 带剩余电流保护塑料外壳式断路器 ( 以下简称断路器 )，是本公司采
用先进的设计软件、制造技术，研制、开发的新型断路器之一。其额定绝缘
电压为 800V，适用于交流 50Hz，额定工作电压 400V，额定工作电流值
630A 的电路中作不频繁转换及电动机不频繁启动之用。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，同时还可以对过电
流保护不能检测出的长期存在的接地故障可能引起火灾危险提供保护。

HBM1L with residual current protection plastic case circuit breaker (hereinafter referred to as circuit breaker) is one of the new circuit breakers
developed and developed by the company using advanced design software and manufacturing technology. Its rated insulation voltage is
800V, suitable for AC 50Hz, rated working voltage 400V, rated operating current value 630A in the circuit for infrequent conversion and motor
infrequent start. The circuit breaker has overload, short-circuit and under-voltage protection functions to protect the line and power supply
equipment from damage. It also protects against long-term ground faults that cannot be detected by overcurrent protection.

◆ 本断路器不可倒进线，即只允许 1、3、5 接电源线，2、4、6 接负载线。
◆ 断路器适用于隔离，符号表示为：
◆ Circuit breakers are classified into M type (higher breaking type) and H type (high breaking type) according to their rated limit short-circuit
breaking capacity (leu). The circuit breaker has the characteristics of small volume, high breaking, arcing end, anti-vibration and the like.
◆ The circuit breaker can be installed vertically (ie, vertically) or horizontally (ie horizontally).
◆ The circuit breaker can't be reversed into the line, that is, only 1, 3, and 5 are connected to the power line, and 2, 4, and 6 are connected to
the load line.
◆ The circuit breaker is suitable for isolation and the symbol is expressed as:
