DAF360 Series Residual Current Circuit Breakers

Introduction

If a ground fault current is detected by the DAF360 residual current circuit breaker, it will compare it to the ground leakage release current value and the circuit breaker will immediately break the circuit if the former is greater than the latter.Circuit breakers can connect ground systems in order to protect the charged body from indirect contact. It also functions to direct contact charged body additional protection if the rated residual current value is greater than or equal to 30mA. Besides the protection of the direct or indirect contact charged body, the circuit breaker also protects against potential fire hazards in case the wiring insulation is damaged.

 Application

The DAF360 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.
