Your Most Reliable Molded Case Circuit Breaker MCCB Supplier - XENHO
Looking for a dependable solution to protect your electrical system from overloads and short circuits? As the professional manufacturer in China, XENHO would like to provide you high quality Molded Case Circuit Breakers, which are built to deliver stable, high-performance protection across industrial and commercial applications. With a full current range from 16A to 1600A, we help you secure your power distribution with confidence.
What is an Molded Case Circuit Breaker?
An Molded Case Circuit Breaker is the “safety guard” of your power system. It automatically disconnects the circuit when abnormal conditions like overload, short circuit, or undervoltage occur.
In practical applications, molded-case circuit breakers are typically installed at the main power distribution level; they are capable of detecting faults in real time and instantaneously interrupting the power supply, thereby effectively preventing equipment damage, eliminating fire hazards, and averting substantial economic losses resulting from downtime.
Core Advantages
1. High Breaking Capacity for Maximum Safety
Our MCCBs are designed to handle high short-circuit currents safely. Even under extreme fault conditions, the breaker reacts instantly to isolate the problem.
2. Dual Protection Mechanism (Thermal + Magnetic)
Thermal Protection: Prevents overload by using bimetal bending
Magnetic Protection: Instantly trips during short circuits
This combination ensures fast and accurate fault response.
3. Intelligent Trip Units (Optional)
For advanced needs, we offer electronic MCCBs with:
Adjustable protection settings
Ground fault protection
Remote monitoring capability
Perfect for smart factories and automated systems.
4. Compact Design, Easy Installation
Compared to traditional breakers, our MCCBs are more compact while maintaining strong performance—saving panel space and installation time.
Technical Highlights
Rated Current: 16A – 1600A
Rated Voltage: Up to 660V (AC/DC)
Breaking Capacity: High Icu / Ics performance
Type: Thermal-Magnetic & Electronic
Applications
Our MCCBs are widely used in:
Industrial plants (motors, compressors, automation lines)
Commercial buildings (shopping malls, offices)
Infrastructure projects (power distribution systems)
They work seamlessly with MCBs and ACBs to form hierarchical protection, ensuring selective tripping and system stability.
