Circuit Breaker Wire Component Supplier – Wire Component For Rccb with Wire and Terminals – Ximu

Introduction

RCD, Residual-Current Device or RCCB, Residual Circuit Current Breaker. It is an electrical wiring device whose function is to disconnect the circuit when it detects currents leaking to the earth wire. It also gives protection against electric shock or electrocution caused by direct contact.

It is a device that has a mechanical switch attached with a residual tripping feature attached to it. It will only break the circuit when there is a leakage current flowing to the earth or also known as earth fault. Wiring rules states that other devices should be operating together with RCCBs to provide protection. This can help improve the short circuit rating of RCCBs.

An ideal circuit is that currents flows through the circuit via the live wire should be the same as the returning current via the neutral wire. However, when an earth fault happens, current enters the earth wire by accident such as accidental contact with open wire. As a result, the current returning through then neutral wire is reduced. The difference in current between the live and neutral wire is called residual current. RCCB is designed such way that it continuously senses the residual current or the difference in current values between the live and neutral wires. Therefore, unless the residual current does not surpass the limit, the RCCB will disconnect the circuit.

Details

The wire components for rcbo consists of wires, terminals, moving contact, static contact and resisitor. 

Our Service

1. Product Customization

Custom MCB parts or components are available upon request.

① How to customize the MCB parts or components?

   Customer offers the sample or technical drawing, our engineer will make few samples for testing in 2 weeks. We will start making the mould after customer checks and confirms the sample.

② How long we take to make a new MCB parts or components？

We need 15 days to make sample for confirming. And making a new mould needs about 45 days.

2. Mature Technology

① We have technicians and toolmakers who can develop and design all kinds of MCB parts or components according to different requirements in the shortest time. All you need to do is to offer samples, profile or drawings.

② Most of the productions are automatic which can lower the cost.

3.Quality Control

We control the quality by many inspections. Firstly we have a incoming inspection for the raw material. And then process inspection for the rivet and stamping. Finally there is final statistical audit.
