Rcd hn52kc024 Contactor 24V 40A 2 Pole 50/60hz

Product Description

The RCD hn52kc024 is a 2-pole definite-purpose contactor rated at 40 amps with a 24-volt coil, designed for use in HVAC systems where reliable load switching is required. It operates on both 50 Hz and 60 Hz electrical systems, making it suitable for a broad range of residential and light commercial applications. The contactor controls high-voltage loads such as compressors and condenser fan motors using a low-voltage 24-volt control circuit. Licensed HVAC technicians install this part as a direct replacement or new installation component in split-system air conditioners and heat pumps.

This contactor is commonly installed in outdoor condensing units, including split-system air conditioners and heat pumps. It is suited for residential and light commercial HVAC equipment where a 2-pole, 40-amp contactor with a 24-volt coil is specified. The 50/60 Hz dual-frequency rating broadens its install compatibility across North American and international-voltage equipment configurations. HVAC service technicians reach for this contactor during seasonal maintenance, compressor circuit diagnostics, and component replacement calls.

Key Features

• 24-volt coil for compatibility with standard low-voltage HVAC control circuits
• 40-amp rating supports compressor and condenser fan motor loads
• 2-pole configuration for single-phase load switching
• Dual-frequency rated at 50 Hz and 60 Hz
• Definite-purpose design built for HVAC compressor contactor applications

Compatibility

Designed as an OEM-style replacement contactor for residential and light commercial HVAC condensing units requiring a 2-pole, 40-amp, 24-volt coil definite-purpose contactor.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect and lock out all power to the condensing unit at the disconnect box before removing or installing the contactor. Verify that the replacement contactor amp rating, pole count, coil voltage, and terminal configuration match the unit requirements before energizing. Follow NEC guidelines for all wiring connections and enclosure reassembly.
