Essential Contactors for HVAC Systems

Explore our range of contactors designed to provide reliable electrical control for HVAC systems. These essential components help manage the flow of electricity, ensuring your system operates smoothly and efficiently.

HVAC Circuit Breakers for System Protection

Circuit breakers protect HVAC equipment from overcurrent and short circuits. The right breaker depends on how many poles it needs to switch.

Breaker Type

Description

Typical Use

Single-pole

Switches one hot leg

120V circuits, small single-phase loads

Double-pole

Switches both hot legs together

208/240V single-phase equipment, most residential AC units

Three-phase (3-pole)

Switches all three phases together

Commercial and industrial HVAC equipment

Choosing the Right Breaker, Contactor, or Disconnect

Match the replacement to your system's nameplate: voltage, amperage, and number of poles for a breaker or disconnect. For a contactor, also confirm the coil voltage, typically 24V control voltage, separately from the load-side voltage.

AC Disconnects for Safe Power Management

AC disconnects are designed for safe, easy power shutdown in HVAC systems. These disconnects ensure that HVAC units can be safely serviced, preventing electrical hazards and downtime.

Fused vs. Non-Fused AC Disconnects

AC disconnects come in fused and non-fused versions. Fused disconnects add overcurrent protection at the disconnect itself, which some local codes require for outdoor AC units, while non-fused disconnects only provide a manual shutoff. Check your local electrical code before choosing between the two.

Frequently Asked Questions
