Product Overview
Molded case circuit breakers are designed to protect electrical circuits by automatically tripping based on thermal and magnetic forces. They quickly cut off power during abnormal current conditions, preventing damage to wires and equipment. Suitable for infrequent circuit switching, these breakers are ideal for building electrical systems and industrial control applications in factory workshops.

Selection Guide
Q1: What size circuit breaker should I choose?
Calculate based on total power (W/watt) and voltage (default 380V for three-phase power). Consider future electrical construction and consumption increases.
Q2: What cable cross-sectional area is required?
Select appropriate cable size in square millimeters. For aluminum cables, consider increasing by one size grade for optimal performance.
Q3: Difference between 3P and 4P configurations
3P: Connects three live wires - suitable for applications without neutral wire requirements. 4P: Connects three live wires and one neutral wire - recommended when converting three-phase motor to 220V lighting power or when utilizing one live wire and neutral wire for 220V voltage conversion.
