Hartland Controls CON-3/480/40 Contactor
The Hartland Controls CON-3/480/40 is a heavy-duty 3 pole contactor designed for demanding commercial HVACR and industrial applications. This definite purpose contactor features a 480Vac 50/60Hz coil voltage and is rated for 40 Amps, making it a reliable choice for switching three-phase motors, compressors, and high-load heating elements. Engineered with silver cadmium oxide contacts, the unit ensures superior conductivity and resistance to welding under rapid cycling or sustained overloads. The Double E magnet assembly provides optimal performance with reduced power consumption, while the 130?C Class B insulation system maintains structural integrity in high-temperature environments. With its commercial HVAC maintenance-ready design, it utilizes aluminum box lug terminations and includes a manual test button for verifying circuit continuity without energizing the coil. This "workhorse" component is essential for HVAC troubleshooting and ensuring energy-efficient HVAC installation in large-scale systems.
Key Benefits:- High Current Capacity: Rated for 40 Amps at 600VAC max, ideal for commercial-grade compressors and motors.
- Robust Contact Material: Silver cadmium oxide movable contacts prevent oxidation and extend operational life in harsh environments.
- Field-Serviceable Design: Features a manual test button and standard 4-14 aluminum box lugs for efficient AC repair services.
- Superior Insulation: Equipped with a 130?C Class B system and arc-resistant polyester actuator to prevent electrical tracking.
- Industry Compliance: Meets UL 508 and CSA standards, ensuring safety and compatibility with existing commercial HVAC systems.
- How do I know if my 480V contactor is failing? Watch for a loud buzzing noise, pitted contacts, or a compressor that won't engage despite receiving a call for cooling. Use a multimeter to check the 480V coil resistance and verify continuity across the poles.
- Can this 3-pole contactor replace a 1-pole or 2-pole unit? While technically possible if the amperage and coil voltage match, it is best practice to use a 3-pole unit for three-phase equipment to prevent single-phasing and motor burnout.
- What is the purpose of the manual test button? It allows a technician to manually close the contacts to test the load circuit without needing to energize the control circuit, simplifying the HVAC troubleshooting process.
