Product Introduction
ZYMM1-250M covers rated current of 100A, 125A, 160A, 180A, 200A, 225A and 250A, rated insulation voltage of 800V, rated impulse withstand voltage of 8000V, rated working voltage of AC 400V and 690V. The MCCB helps to protect the system from faults such as overloads and short circuits and can be released either thermomagnetically or microprocessorically. the MCCB fulfils the requirement for isolation as it provides complete isolation for the circuit.
Yuming Electric’s moulded case circuit breaker has easy installation, high quality and good performance. It is commonly used in residential or industrial sector to sense abnormal conditions such as short circuits and overloads.

Features
◆ Their compact size saves a lot of space in the panel design.
◆ Protection of the circuit from overload by means of a manual switch.
◆ Versatility and high performance of the system.
Inside Structure
The application of molded case circuit breakers (MCCBs) in various industries has revolutionized the way electrical systems operate. The MCCB is an important component to ensure the safe and efficient operation of the circuit. They provide protection against overloads, short circuits, and other electrical faults, which are critical in preventing electrical accidents and fire hazards.
FAQ
Q:What is the life of MCCB?
A:Industry life expectancy for moulded case circuit breakers is generally around 30 years, taking into account favourable environments and regular maintenance.
Q:Do MCCB has short time withstand rating?
A:The MCCB is a downstream protection device and therefore needs to sense and clear circuit faults instantly and without any delay. For this reason, MCCBs do not need to have any short time withstand voltage rating. However, MCCBs rated at 1000A and above also have a short time withstand voltage rating.
