China wholesale Mccb Electromagnetic System Suppliers – XML7M MCB Circuit Breaker Electro-Magnetic Protection – Ximu

Introduction

An MCB or miniature circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current, typically resulting from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected.

It is an electromagnetic device that embodies a complete enclosure in a molded insulating material. The main function of an MCB is to switch the circuit, i.e., to open the circuit (which has been connected to it) automatically when the current passing through it (MCB) exceeds the value for which it is set. It can be manually switched ON and OFF as similar to normal switch if necessary.

Details

The XML7M MCB Circuit Breaker Electro-Magnetic Protection consists of coil, yoke, iron core, fix contact, and terminal.

During short circuit condition, the current rises suddenly, causing electromechanical displacement of plunger associated with a tripping coil or solenoid. The plunger strikes the trip lever causing immediate release of latch mechanism consequently open the circuit breaker contacts. This was a simple explanation of a miniature circuit breaker working principle.

The most important thing that Circuit Breaker is doing is to safely and reliably switches off electrical circuit during abnormal conditions of the network, that means over load condition as well as faulty condition.

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.
