Description
4-Pole Magnetic Contactor: Full Details
A 4-pole magnetic contactor is a versatile and reliable switching device used to control and manage electrical circuits. It is specifically designed for applications that require switching multiple circuits or controlling three-phase systems with a neutral wire.
Key Features
Four Independent Poles:
Each pole switches independently, enabling it to control complex electrical systems, such as three-phase systems with neutral or multiple circuits.
Electromagnetic Operation:
Operated by an electromagnetic coil that opens or closes the contacts, ensuring smooth and quick switching.
High Switching Capacity:
Designed to handle large currents and high voltages, making it suitable for industrial and commercial applications.
Durable Build:
Made with high-quality materials for long-lasting performance under frequent operation.
Arc Extinguishing System:
Built-in arc chambers to safely extinguish arcs during switching, ensuring operational safety.
Auxiliary Contacts:
Includes auxiliary contacts for additional signaling or interlocking functions.
Compact Design:
Space-saving form factor for easy integration into electrical panels.
