Hubbell Industrial Controls 75D50833H Relay Coil
The Hubbell Industrial Controls 75D50833H Relay Coil is a heavy-duty 480V replacement coil engineered specifically for Class 47 alternating relays and industrial motor control applications. This field-installable high-voltage relay coil is built for the rigorous demands of pump panels, compressor stations, and factory automation environments where 480VAC line voltage is utilized for the control circuit. In industrial HVACR systems, this coil manages the alternating operation of dual-motor setups, ensuring balanced wear across components. The Hubbell 75D50833H features a robust winding design compatible with 50/60Hz frequencies, providing consistent magnetic pull for silver cadmium oxide contacts without the risk of chatter. Weighing approximately 0.24 lbs, this OEM part is the exact technical match for NEMA-rated industrial controllers requiring a 480V alternating relay interface. Proper installation of this industrial control coil ensures precise power distribution and prevents system overloads by maintaining reliable switching cycles in high-demand machinery like fans and heavy-duty compressors.
Key Benefits
- Industrial Durability: Specifically designed for 480V environments, reducing the need for step-down control transformers in pump and compressor panels.
- Operational Efficiency: Optimizes alternating motor cycles for dual-pump systems, extending the service life of much larger mechanical components.
- Precision Engineering: Reliable 50/60Hz frequency response prevents relay chatter and ensures secure contact sealing under high-load conditions.
- Direct Compatibility: Built by Hubbell Industrial Controls (ICD) to fit Class 47 structures for seamless field replacement with zero modifications.
Common Questions
Can I use this 480V coil in a 120V or 240V control circuit?
No, relay coils are voltage-specific. Attempting to use a 480V coil with lower voltages will fail to generate sufficient magnetic flux to close the contacts, resulting in system failure.
Is this coil compatible with other brands of alternating relays?
This part is specifically engineered for Hubbell/Furnas Class 47 series alternating relays. Always verify that your part number is an exact match before installation.
What are the symptoms of a failing 480V relay coil?
Common indicators include a burnt electrical odor, visible swelling of the coil housing, or a relay that fails to switch even when control voltage is confirmed at the terminals.
