Designed for long service life, this 400V 7Pins Three Phase With Emergency Stop Cover Electromagnetic Switch (internal model: YCZ4-A) features a high rated current and excellent sealing performance. Fitted with pre-installed external plug-in terminals, it can easily connect with auxiliary devices such as overload protectors, limit switches, temperature controllers and Hall sensors to form a complete safety circuit. When equipment malfunctions, it immediately cuts off the main power supply to avoid potential accidents.
In addition, the switch is equipped with advanced power failure and undervoltage protection. It automatically disconnects the main power in case of power outage or low voltage. Manual reset via the pushbutton is required to restart the system, effectively preventing dangerous and unexpected automatic startup of connected machinery.
