Product Description

Introduction
 

DAL10-63 residual current circuit breakers are protection equipment which must be used to protect human life against dangerous electric shocks or prevent the fires arising out of isolation mistakes thereby detecting isolation mistakes to occur within the plant in advance. Sigma residual current circuit breakers are produced with 2 and 4 poles in accordance with IEC EN 61008-1 standard and in compliance with CE norms under ISO 9001:2008 quality assurance system.

Application

The  residual current circuit breaker is designed to meet GB16916.1, IEC61008 and BS4293 standards. It is used in situations requiring alternating current 50-60Hz, single-phase 240V (220V), three-phase 415V (380V) such as industrial and mining operations, commerce and household. It can be used for infrequent conversion of lines under normal circumstances when functions as a personal electric shock and equipment leakage protection device.

Tripping sensitivity
10mA-precision instrument leakage protection and bathroom use
30mA-additional protection against direct contact.
100mA-co-ordinated with the earth system according to the formula I△n<50/R, to provide protection against indirect contacts;
300mA-protection against indirect contacts, as well as fire hazard.

 

What is the difference between electromagnetic and electronic type of residual current circuit breakers?

Electromegnetic type residual current circuit breakers do not need auxiliary voltage for tripping case of any residual current.

Thus it ensures exact safety thereby performing its function independent of supply voltages even in case of low and high voltages. Equipment operating under electro mechanic method maintain to protect residual current in the phase line which they supply even in case of disconnection of neutral line. As the

electronic type residual current circuit breakers need auxiliary voltage, it is risky to use them. Because auxiliary voltage will be disconnected in case of any neutral disconnection they are unable to carry out protection function. Due to such obstacles,electronic type residual current circuit breakers are not allowed to be used in our country by the ministry of public works and settlement.
