iALM1E Electronic Molded Case Circuit Breaker

Product Overview

iALM1E series electronic molded case circuit breaker (hereinafter referred to as circuit breaker) is one of the new circuit breakers developed by our company with international advanced technology. lt has the characteristics of four segments selective protection, high breaking, small and compact structure, etc.

The circuit breaker is classified into M type (higher breaking type) and H type (high break-ing type) according to rated limit short-circuit breaking capacity (lcu). t is an ideal product for power distribution and motor protection. its rated insulation voltage is 1000V, which applies to the AC 50/60Hz circuit with a rated working voltage of 690V and below, and a setting current from 12.5A to 800A for infrequent line conversion and infrequent motor startup.

A module with a communication function can be added to the circuit breaker so that the orig. final circuit breaker can be easily upgraded to a communication-type circuit breaker.

The circuit breaker has the functions of overload long time delay, short circuit short time delay. short circuit instantaneous and grounding protection, The product can be equipped with under voltage, shunt, auxiliary, alarm, communication, and other accessories.

This series of circuit breakers can be installed vertically (i.e. upright) or horizontally (i.e. trans-herself).

With the isolation function, the corresponding symbol is Note: 3P+N has no isolation function and has a unique “overload alarm without tripping” function to ensure the continuity of the power supply.

The circuit breaker complies with series standards:

EC/EN 60947-1 and GB/T 14048.1 Low-voltage switchgear and controlgear-Part 1: Generarules.

EC/EN 60947-2 and GB/T 14048.2 Low voltage switchgear and controlgear Part 2: Circuitbreakers.
