Application
The P170DA-400 is ideal for use as a high-side safety cutout on air conditioning and refrigeration systems using R410A or similar high-pressure refrigerants. The manual reset lockout feature ensures that a technician must physically reset the control after a high-pressure trip, preventing automatic restart until the root cause has been identified and corrected. This adds an important layer of protection against compressor damage and system failures.
