Molded Case Circuit Breaker is a kind of mechanical equipment that can generate, transfer and disconnect current under normal circuit conditions, and can also generate under specified abnormal circuit conditions (such as short circuit and over current) for a specified time And off current.

MATYS dual-power automatic change-over switch is an automaticswitching switch that integrates switching and logic control and realizes mechanical-electrical integration. It is suitable for power distribution equipment in industrial enterprises with 50 Hz AC, rated voltage to 440 V and agreed heating current to 3200 A. It has the functions of voltage detection, communication interface, electrical and mechanical interlocking, etc. It can realize automatic, remote control, forced to position "0" and emergency manual operation. It is widely used in automatic conversion between main power supply and standby power supply of power supply system or automatic conversion and safety isolation of two load equipment. Switches with logic commands issued by the control circuit board to control the generators. The generator drives the operating mechanism of the main part of the switch. The switch can quickly make and break circuits or switch on the circuit or convert the circuit. Safety isolation can be achieved through the obvious visible state.
