EZC Molded Case Circuit Breaker 100A–1600A for Low-Voltage Power Distribution

The EZC Molded Case Circuit Breaker 100A–1600A is designed for low-voltage power distribution systems where dependable circuit protection and practical installation are required. This model is intended for use as both a main incoming breaker and a feeder protection device in industrial and commercial electrical networks.

Functional Design and Protection Performance

The EZC MCCB is built around a thermal-magnetic protection concept that enables effective response to abnormal current conditions. During sustained overload situations, the thermal protection mechanism reacts progressively to prevent excessive heating of conductors and connected equipment. When short-circuit faults occur, the magnetic release operates rapidly to disconnect the circuit and limit fault energy.

This coordinated protection behavior helps maintain system stability and supports safe operation across a wide range of operating conditions.

Mechanical Structure and Insulation Characteristics

The breaker features a molded insulating case that provides mechanical strength and reliable electrical insulation. The internal contact system is designed to maintain stable conductivity during normal operation while supporting consistent interruption performance during fault conditions.

Its compact structural layout allows efficient integration into low-voltage distribution boards, control cabinets, and power panels, helping optimize space utilization within electrical enclosures.

Application Scope and Installation

Covering a current range from 100A to 1600A, the EZC MCCB is suitable for a variety of distribution tasks, including feeder protection, equipment isolation, and branch circuit control. The product supports multiple installation configurations, enabling straightforward mounting and wiring in standardized low-voltage systems.

Typical application environments include manufacturing facilities, commercial buildings, infrastructure projects, and general-purpose power distribution systems that require reliable protection without excessive system complexity.

Operational Reliability and Quality Control

Each EZC molded case circuit breaker is produced under controlled manufacturing processes and undergoes functional inspection prior to shipment. Key operational elements, including the tripping mechanism and contact assembly, are verified to ensure consistent performance and dependable operation throughout the product’s service life.

The EZC MCCB offers a balanced solution combining practical protection functionality, stable mechanical design, and broad application adaptability for low-voltage distribution systems.
