Features
- Brownout protection
- UL 873 recognition as compressor controller
- Helps prevent scroll compressor reversal
- 3-10 minute adjustable time delay
- Fast response time: 16ms
- Prevents low voltage starts
- Eliminates relay chatter due to thermostat bounce or tampering
- Works with anticipator-type thermostats Patented: US Parent No. 4,991,049
Mode of Operation - Upon application power, the load is energized. When the thermostat or other switch opens or there is a loss of power, the load is de-energized and the delay period begins. The compressor will not start again during the delay period. Restart occurs after the delay period has elapsed.
Installation & Operation Notes:
- Disconnect power at all sources and verify that all circuits are de-energized before starting work
- Mount the contactor securely in the control compartment or electrical panel as directed by the equipment manufacturer
- Move line, load, and control wires from the existing contactor to the new contactor, matching wiring diagrams and terminal markings
- After energizing the system, verify that the contactor pulls in and opens cleanly, with proper operation during system start and stop cycles
- Confirm that all terminations are tight and that wiring is supported to prevent strain at the terminals
Maintenance & Troubleshooting:
- Inspect the contactor during routine HVAC maintenance for pitted or burned contacts, coil discoloration, or mechanical binding
- Replace the contactor if the coil fails to energize, if the contacts do not close fully, or if there is evidence of overheating or excessive humming
- If repeated contactor issues occur, verify that load current and control voltage are within specification and that short cycling is not overstressing the contactor
Certifications & Compliance:
- Meets ARI 780/790 Standard
User Reviews & Q&A Summary:
- Common theme is "correct part" for the intended replacement, with users reporting it worked as expected after installation
- Review feedback frequently mentions straightforward installation for a direct replacement
- Value and fulfillment are recurring positives (good deal/price and fast shipping)
