24V Contactor

24V Contactors

24V contactors are often used in HVAC and air compressor applications, and can have DC, AC, or DC/AC coils.

Your choice of coil voltage depends on what kind of power supply you have available for the control circuit powering your contactor. Lower voltages are safer for both AC and DC. However, keeping power consumption constant, lower voltages mean you will have higher current (amps) and will require larger coils to prevent overloading (electric current generates heat, and too much current will overheat and damage the coils and the contactor).

A 24V contactor with an AC coil may be used where safety is an issue. It is also easier to provide 24V AC as long as you are able to step-down the voltage coming from your outlets, while a 24V contactor with a DC coil will require either some sort of battery power or a rectifier to convert the AC power coming from your local power lines.

Practically speaking, the primary difference between AC and DC power is the fact that damage from arcing is far more of a concern for DC circuits than AC.
