Climatemaster C13B0055N01 Low Pressure Switch 35-60 Psi

Product Description

The CLIMATEMASTER C13B0055N01 is a low pressure switch designed to monitor fluid or refrigerant pressure in HVAC systems. When system pressure moves outside the 35 to 60 psi operating range, the switch opens or closes its internal electrical contacts to interrupt the control circuit and trigger a protective response. This prevents compressor damage and system faults caused by abnormal pressure conditions. Licensed HVAC technicians install this switch in refrigeration or hydronic lines as part of standard compressor protection and system safety wiring.

This switch is suited for use in residential and light commercial heat pump and air conditioning equipment. It is installed inline with refrigeration or hydronic lines and wired into the compressor control circuit. The switch provides an automatic cutout response when monitored pressure falls below or rises above the set range, supporting reliable system operation and protection during abnormal operating conditions.

Key Features

• Pressure sensing range of 35 to 60 psi for low-side monitoring
• Opens or closes internal electrical contacts on pressure deviation
• Interrupts control circuit to initiate protective system response
• Compatible with refrigerant and hydronic fluid lines
• Supports compressor protection in heat pump and air conditioning systems

Compatibility

Designed as an OEM-style replacement low pressure switch for use in heat pump and air conditioning systems requiring 35 to 60 psi low-side pressure protection.

Installation Notes

Installation should be performed by a licensed HVAC technician following applicable mechanical and refrigeration codes. Power down the unit and recover refrigerant or depressurize the hydronic circuit before removing or installing the switch. Verify control circuit wiring connections are secure and that the switch is installed in the correct orientation per the system schematic before restarting the equipment.
