This bundle expands to three 40A 4-pole NO contactors with a power status indicator, plus an 8″ DIN rail and screws for installation. Like the other Electrodepot options, it supports AC-1 and AC-3 loads and operates at 110/120VAC with silent coil operation. Inductive/motor load up to 40A, resistive/incandescent up to 63A, and DC load up to 30A at 24VDC. It is suitable for installations requiring more contactors in a compact DIN rail footprint, such as larger HVAC or process control panels.

Best for: systems needing additional contactor capacity on a single DIN rail. Better for: installations requiring three contactors in one package. Caution: the longer DIN rail length requires space planning to avoid overcrowding near wiring terminals.

Designed for 120VAC coil operation, this 8-pole, 4-pole-per-side contactor features a silent, energy-saving coil and a mounting base for easy DIN rail installation. Inductive/motor load rating is 40A, while resistive/incandescent loads peak at 60A. It is compatible with DIN rails and includes a power status indicator for quick sanity checks in control panels. This option is a strong choice for HVAC contractors and industrial electricians focusing on compact, reliable switching.

Best for: users needing a compact, DIN rail-ready contactor with reliable silent operation. Better for: HVAC and refrigeration control panels where space is constrained. Caution: ensure compatibility with existing DIN rail size and mounting hardware in older panels.

4 Pole Contactor 120V Coil – 60A

Check Price on Amazon

Although labeled as a 4-pole unit, this model provides 120V coil operation with a robust 63A resistive/incandescent load and 40A inductive/motor load, making it a practical choice for certain 8-pole system configurations when combined with a companion unit. The design includes a DIN rail mounting base and a status indicator. It is well-suited for HVAC compressor and motor control tasks. This option is best for building modular, mixed-pole control systems where space or functional segmentation matters.

Best for: modular panel builders who need a strong 4-pole unit as part of an 8-pole setup. Better for: configurations where separate sections control different loads. Caution: confirm the specific 8-pole requirement and whether this unit should be paired with another contactor for full 8-pole coverage.

Buying Guide

What to consider when choosing an 8 pole contactor

• Coil voltage compatibility: Most options use 110/120VAC. Confirm that your system’s control voltage aligns with the coil rating (50/60 Hz typical).
• Load ratings: Inductive/motor load around 40A is common; resistive/incandescent loads around 60–63A. Match these to the equipment you’re switching (fans, motors, lighting, heaters).
• Pole configuration: 8 pole (4 pole x 2) arrangements are useful for two separate circuits or multi-pole switching. Ensure wiring terminals and space accommodate two banks.
• DIN rail compatibility: Most bundles include a 35mm wide rail; verify length and mounting depth fit your panel’s interior.
• Coil inrush and noise: Look for silent operation coils and stated inrush values to plan for power delivery and electrical interference.
• Accessory inclusion: Bundles often include DIN rails and mounting screws. If not, consider compatible hardware to avoid project delays.
• Application rating: AC-1 vs AC-3 applications indicate suitability for furnaces/heaters versus compressors/fans. Choose based on your load type.
• Physical footprint: Consider the combined width if installing two contactors side by side on a single DIN rail to avoid crowding.

FAQ

1. What does 8 pole mean in contactors?

   It refers to two 4-pole contactors operated together, providing eight switching contacts for multi-circuit control, often used in HVAC or motor control panels.

2. Can I install these on a standard DIN rail?

   Yes, all recommended bundles include a DIN rail compatible with common 35mm x 150mm or 35mm x 200mm rails. Verify the rail length and enclosure space.

3. Which load rating matters most?

   Inductive/motor loads (amps for motors) are typically the limiting factor for startup currents; ensure the coil and contactor can handle your peak inrush. Resistive loads are generally higher and easier to manage.

4. Is silent operation important for contactors?

   Silent operation reduces audible humming and is beneficial in noise-sensitive installations, such as offices or quiet HVAC rooms.

5. Do all these units require same voltage supply?

   Most are designed for 110/120VAC control voltage; confirm that your control circuit voltage matches to prevent malfunction.

6. What is the advantage of buying a bundle?

   Bundles provide all necessary mounting hardware, rails, and usually multiple contactors, reducing setup time and ensuring consistent compatibility.
