Raychem cch-2c Crankcase Heater 240 Volt

Product Description

The RAYCHEM cch-2c is a self-regulating crankcase heater designed to protect compressor oil in residential and light commercial refrigeration and air conditioning systems. Crankcase heaters prevent refrigerant migration into the compressor sump during off cycles, which can cause oil foaming and compressor damage on startup. The cch-2c operates across a voltage range of 208 to 277 volts, making it compatible with both standard 208V and 240V single-phase circuits. It features a flexible lock strap design with pre-stripped cold leads for direct hard-wire installation without additional connectors.

This crankcase heater is suited for residential split systems and light commercial condensing units where compressor protection during shutdown periods is required. The flexible strap design allows it to wrap around a variety of compressor housings, conforming to the shell for consistent heat transfer. HVAC technicians install this heater as part of routine compressor protection practice, particularly in regions with cold ambient temperatures where refrigerant migration risk is elevated.

Key Features

• Self-regulating crankcase heater reduces refrigerant migration into compressor oil during off cycles
• Operates at 208 to 277 volts, covering standard 208V and 240V single-phase applications
• Flexible lock strap secures heater firmly around the compressor shell
• Pre-stripped cold leads allow direct hard-wire connection without additional prep
• Designed for wrap-around installation on a range of compressor housing diameters

Compatibility

Designed as an OEM-style replacement crankcase heater for residential and light commercial air conditioning and refrigeration compressors requiring 208 to 277 volt crankcase heat protection.

Installation Notes

Crankcase heater installation is typically performed by licensed HVAC technicians. Always disconnect and lock out power to the unit before handling the heater or any wiring. Route and secure the strap snugly around the lower portion of the compressor shell, then hard-wire the cold leads to the appropriate circuit per local electrical codes and NEC requirements. Allow the heater sufficient warm-up time before energizing the compressor after installation.
