Marley Engineered Products 5018-0006-000 Contactor

The Marley Engineered Products 5018-0006-000 Contactor is a heavy-duty 3-pole relay engineered for precise switching in commercial and industrial HVACR systems. As an authentic OEM component, this Marley 5018-0006-000 features a 24V coil voltage and a robust 40A current rating, making it a critical choice for managing high-load circuits in electric heaters, blowers, and air conditioning units. The triple-pole configuration allows for the simultaneous control of three separate electrical lines, ensuring reliable operation of multi-phase equipment. Field technicians prioritize this 40 amp contactor for its direct-fit compatibility and durable contact surfaces that resist pitting and welding under high-cycle demands. Designed to meet strict engineering standards, this 24V HVAC contactor provides low power consumption at the coil while maintaining secure terminal connections for long-term electrical stability in the field.

• OEM Compatibility: Precision-engineered for a seamless drop-in replacement in Marley Engineered Products and Berko heating units.
• High Load Capacity: Rated for 40A inductive loads, providing overhead for demanding motor and heater applications.
• Reliable Coil Operation: The 24V AC coil ensures compatibility with standard HVAC control transformers and thermostats.
• Triple Pole Control: 3-pole design offers versatile wiring options for single-phase or three-phase equipment configurations.
• Industrial Durability: Constructed with high-grade materials to withstand the thermal stressors found in commercial mechanical rooms.

What is the difference between a 3-pole and a 2-pole contactor in this application?
A 3-pole contactor like the 5018-0006-000 provides three sets of contacts, allowing for the switching of all three phases of a three-phase power supply or multiple circuits simultaneously, whereas a 2-pole only switches two.

Can this contactor replace a lower-rated 30A model?
Yes, provided the physical footprint and 24V coil voltage match. Using a 40A contactor to replace a 30A unit provides extra capacity, which often results in longer contact life due to reduced thermal stress.

Is the coil voltage 24V DC or 24V AC?
The Marley 5018-0006-000 is designed for 24V AC control circuits, which is the standard for most commercial HVAC equipment and building automation systems.
