Daikin-McQuay 028210101 Relay
The Daikin-McQuay 028210101 Relay is a critical component for specialized HVAC part winding start configurations, specifically engineered to manage the staged energization of compressor windings. This 115V time delay relay provides a fixed 1-second delay, ensuring the initial current inrush is mitigated before the secondary winding is engaged. For technicians working on large tonnage McQuay chillers or commercial DX systems, maintaining the precise timing of this OEM replacement relay is essential to prevent circuit breaker tripping and excessive mechanical stress on the motor. Constructed to meet rigorous industrial standards, the 028210101 1-second timer features high-reliability contacts capable of handling the rapid switching cycles required in complex power distribution circuits. Whether you are performing a compressor relay replacement or troubleshooting a part winding motor control issue, this genuine Daikin part ensures electrical compatibility and restores factory-spec performance. This unit replaces several legacy numbers, including 282101B-01 and 282101D-01, providing a direct-pull solution for maintenance and repair.
Key Benefits
- Precision 1-Second Delay: Specifically calibrated for part winding start sequences to protect high-torque compressor motors from voltage drops.
- Industrial-Grade 115V Coil: Designed for continuous duty in demanding commercial HVACR environments.
- Genuine OEM Replacement: Ensures 1:1 fitment and eliminates the risks associated with generic universal timers that may drift over time.
- Legacy Compatibility: Directly replaces multiple retired McQuay part numbers, simplifying inventory for service contractors.
Common Questions
What is the primary function of the 028210101 relay in a part winding start?
It provides the necessary 1-second interval between the energization of the first and second sets of motor windings to reduce the starting current (LRA).
Can this relay be used in 24V control circuits?
No, this specific model is designed for 115V coil applications. Always verify your control transformer output before installation.
How do I know if my 1-second time delay relay has failed?
Common symptoms include the compressor failing to transition to the second winding or immediate nuisance tripping of the branch circuit protection upon startup.
