Hubbell Industrial Controls 47AB10BH Relay
The Hubbell Industrial Controls 47AB10BH Relay is a heavy-duty 480V alternating relay engineered for industrial duplex pump and compressor control systems. As a veteran-grade Type 5247 alternating relay, it provides a reliable mechanical means to automatically alternate the operation of two separate motor-driven loads. This lead-lag functionality ensures even mechanical wear and maximizes system uptime. Designed for 480V alternating relay applications, the 47AB10BH features SPDT 10 Amp contacts made of silver cadmium oxide, housed within a transparent dust cover for easy inspection. The NEMA A600 rating confirms its suitability for high-demand industrial control relay environments, while the front-wired configuration allows for efficient integration into NEMA 1 enclosures or custom control panels. With no-load transfer logic, the contacts only transition when the unit is de-energized, preventing arcing and significantly extending the service life of your motor starters and associated HVAC switchgear.
Key Benefits for Contractors:- Optimized Load Balancing: Automatically alternates between two motors to prevent uneven component fatigue and premature system failure.
- Rugged Industrial Build: Features a robust Class 47 alternator design capable of handling high-voltage 50/60 Hz industrial circuits.
- Superior Contact Reliability: Heavy-duty 10-amp silver cadmium oxide contacts facilitate high-inrush current handling without pitting.
- Simplified Field Installation: Front-wired design and NEMA 1 enclosure compatibility streamline mounting in tight electrical cabinets.
- Certified Compliance: UL Listed and CSA Certified for professional-grade safety in commercial and industrial HVACR projects.
How do I wire a Hubbell 47AB10BH for duplex pump control?
The relay should be wired into the control circuit so that each time the pilot device (like a float switch) opens, the 47AB10BH toggles the load path to the opposite motor starter. For 480V applications, ensure the coil is fed across two hot phases (L1-L2) rather than to neutral, maintaining proper industrial motor control standards.
Can the 47AB10BH be used in a NEMA 4 environment?
The standard unit is designed for NEMA 1 indoor use. For wash-down or outdoor applications, the relay must be installed within a secondary NEMA 4 or 4X rated enclosure to protect the internal Type 5247 mechanism from moisture and corrosion.
What is the benefit of the 'No-Load Transfer' feature?
No-load transfer ensures the internal alternating relay contacts do not "make or break" while carrying full current. This prevents contact welding and electrical noise, preserving the integrity of the power distribution circuit.
