Feature: 1. Flame Retardant Housing: The housing of this AC contactor is made of PC material, which is a high performance engineering plastic to ensure the safety of electricity. This material has high sensitivity and high load bearing capacity. 2. Winding Copper Core Coils: This AC contactor uses a strong resistive coil to flow current to produce a magnetic field that closes the contacts to achieve electrical installation to control the load. 3. 32 Pieces Of Iron Core: This core is made of silver alloy material. The silver alloy contacts are highly conductive, carry more current, have fuller quality, and absorb more smoothly, making the core better quality. 4. Easy Installation: This AC contactor has a convenient anticracking clip design and a solid screw mounting, making it very easy to install. 5. Wide Application: This AC contactor is widely used to turn on and break circuits over long distances, frequently start and control AC motors.
