FAQ

What is a contactor and how is it different from a relay? 

A contactor is a high-power electrically operated switch for heavy-duty circuits like motors or heaters, whereas relays handle lower current loads. 

What do auxiliary contacts do? 

Auxiliary contacts are low-current "signal" switches used for control functions like latching starters or triggering alarms they don’t carry the main load. 

How does a thermal overload relay protect motors? 

It uses a bimetallic strip to detect excessive heat from overloads and trips, interrupting the contactor control circuit to prevent motor damage. 

What are reset options for thermal overload relays? 

Thermal overload relays come with either manual reset requiring operator action—or automatic reset, which restores power once the unit cools. 

What information is needed to select the right contactor setup? 

You should specify the main contactor rating (amps, poles), auxiliary contact types, and coil voltage (including AC/DC and frequency) per application needs.
