■产品概述Application Scope

ARHM3系列塑料外壳式断路器(以下简称断路器)，适用于交流50/60Hz，其额定绝缘电压至80OV，额定工作电压415V，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(Inm≤400A及以下)。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。该断路器具有体积小、分断能力高、飞弧短、抗振动等特点。

断路器可垂直安装(即竖装)，亦可水平安装(即横装)。

断路器具有隔离功能,其相应符号为:“”。

ARHM3 series moulded case circuit breaker (hereinafter referred to as the circuit breaker), a new style with rated insulatiot

voltage of

8OoV, is adopted to the international advanced design and R&D of manufacturing technology by the company, and is suitable for occasionalconversion and motor protection (the rated current ≤ 400A type without motor protection) under the circuit of AC 50Hz/6O0Hz

as well as

rated current to 800A. The circuit breaker has prolection function to avoid overload, short circuit and under-voltage, for assuring theprevention from damage of circuits and power-supply devices.it has features of small volume, high breaking and short flashover (Zeroflashover of partial sizes), vibration resistance, etc.

lt can be installed vertically (vertical assembly) or horizontally (horizontal assembly).lt has isolation function, with its corresponding symbol of.
