Frequently Asked Questions
How do I size a contactor?
By the motor's full-load current and utilization category (AC-3 for motors). Match the coil voltage to your control circuit.
What's a definite-purpose vs IEC contactor?
Definite-purpose contactors are cost-optimized for specific loads like HVAC; IEC contactors are compact, modular, and rated by utilization category.
Do these include overload protection?
Contactors switch; pair them with a matching overload relay for motor protection. We stock both.
