We can offer you M1 series MCCB (Molded Case Circuit Breaker) SKD solutions to help lower production costs and import duties. These circuit breakers are designed for AC 50Hz (or 60Hz) systems, with a rated insulation voltage of 800V, operating voltage up to 690V, and suitable for circuits up to 1250A.
Our SKD package includes pre-tested components that ensure reliable performance. The circuit breakers offer protection against overloads, undervoltage, and short circuits. Models with a 400A shell and below can also be used for motor protection.
With this solution, you can easily assemble the components to meet local requirements, saving on shipping and import tariffs, while adapting quickly to market demands.
1. The circuit breaker has overload, short circuit and undervoltage protection functions, which can protect the line and power equipment from damage. At the same time, it can provide indirect contact protection for people, and can also provide protection for long-term grounding fault that cannot be detected by over-current protection, which may cause fire hazard.
2. The circuit breaker has the characteristics of small volume, high breaking height, short arcing and anti vibration.
3. The circuit breaker can be installed vertically and horizontally.
4. The circuit breaker cannot be switched in, that is, only 1, 3 and 5 are allowed as power terminals, and 2, 4 and 6 are load terminals.
5. The circuit breaker can be divided into front wiring, back wiring and plug-in wiring.
