Description

Overview

Carrier Transicold High Pressure Switch is a safety cut-out switch for selected transport refrigeration systems. It monitors high-side refrigerant pressure and signals the unit to respond when pressure rises beyond the normal operating range. Match the unit model and switch fitment before ordering, as pressure faults can also be caused by airflow, charge, or condenser issues.

Features

• High-side pressure safety switch for refrigeration control circuits
• Suits selected Carrier Transicold Supra and Vector units
• Used to support correct shutdown or fault response during high pressure events
• Replacement switch for the listed unit ranges
