Core Product Advantages and Features
8 sets of normally open contacts
All 8 pole contacts are normally open (NO), which can control multiple independent circuits simultaneously, expanding the number of control circuits.
110V DC coil
The coil has a rated control voltage of 110V DC and is suitable for medium-voltage DC control systems and some European standard panel configurations.
Screw terminal design
Both the main and auxiliary circuits use screw terminals for connection, making wiring construction and maintenance identification relatively intuitive.
