What is the difference between a contactor and a relay?

A relay is typically used for switching control or signal level circuits, while a contactor is designed to switch higher current loads such as motors, heating elements, and power circuits. Contactors are commonly used in industrial and commercial applications where frequent switching is required.

How do I choose the right contactor for my application?

Selection depends on the load type, rated current and voltage, control coil voltage, number of poles, and the application environment. For motor applications, factors such as starting current and duty cycle should also be considered.

Do you offer both AC and DC contactors?

Yes. We supply AC contactors for general power switching, motor control, and HVAC systems, as well as DC contactors for battery systems, DC motors, and DC control circuits.

What are reversing contactors used for?

Reversing contactors are used to change motor rotation direction by reversing the phase sequence. They are commonly applied in conveyors, hoists, elevators, gates, and other equipment requiring forward and reverse operation.

When should a thermal overload relay be used?

Thermal overload relays are used to protect motors from overload and phase loss conditions. They are typically paired with contactors in motor starter assemblies to help prevent motor damage.

Are miniature contactors suitable for industrial use?

Yes. Miniature contactors are designed for space limited panels and lower current applications, typically from 9A to 32A. They are widely used in control panels, HVAC units, and compact OEM equipment.

Do your contactors and relays comply with international standards?

Yes. Our contactors and relays are manufactured in accordance with IEC and other applicable international standards, supporting safe and reliable operation across global markets.

Can auxiliary contacts be added to contactors?

Auxiliary contacts can be added to provide status indication, interlocking, and feedback signals within control circuits.
