Choosing a contactor often comes down to matching the switch to the job: replacing a worn part in an air conditioner or wiring motor and lighting circuits in an industrial panel. The HIATSU Motor Contactor is priced at $13.68, while the Shopcorp Contactor sits at $99.95, but the choice isn't only about cost. Coil voltage, pole count, and mounting style determine whether the contactor will work in your panel. Whether you're maintaining an HVAC unit or building a new control panel, these two contactors represent very different trade-offs.
Quick Verdict
For an HVAC or air conditioner contactor replacement, the HIATSU is the straightforward choice. For motor and lighting switching, the Shopcorp is the more capable option. If you're unsure which applies to you, the table below outlines the key differences.
At a Glance
| Feature | HIATSU Motor Contactor | Shopcorp Contactor |
| Price | $13.68 | $99.95 |
| Coil voltage | 120V | 24V |
| Pole count | 2 | 4 |
| Mounting / connections | Quick-connect terminals | DIN rail mount |
| Best for | Air conditioner / HVAC replacement | Motor and lighting loads, industrial control |
Where Each Product Wins
- HIATSU wins for HVAC service because it arrives as a single included contactor, uses an encapsulated coil, and carries CE and RoHS compliance. The HIATSU is aimed at keeping an existing HVAC system running.
- Shopcorp wins for industrial control because the normally closed switching layout, power status indicator, and silent no-humming coil support motor, lighting, compressor, and HVAC applications. The Shopcorp is designed for new or upgraded control panels.
Product Breakdown
HIATSU Motor Contactor
The HIATSU Motor Contactor is a 2-pole, 30A unit built around dual-circuit control. It features an encapsulated coil, quick-connect terminals, and heavy-duty construction, with copper material used in the construction, and the package includes a single contactor. It also carries CE and RoHS compliance, which are typical markers for HVAC components. The limitation is the 2-pole layout: you get fewer switching paths than the Shopcorp, so it is best when you only need to switch two circuits at once. For a straightforward HVAC or air conditioner contactor replacement, that is usually enough, but a multi-circuit industrial panel will quickly outgrow it.
Shopcorp Contactor
The Shopcorp Contactor targets DIN rail-mounted control with a normally closed switching layout and a 24V coil. It offers silent no-humming operation, a power status indicator, IEC/EN compliance, and a 400V rating, with use cases covering motor, lighting, compressor, and HVAC loads. The normally closed layout is a defining feature of this unit. The limitation is the 24V coil: if your existing control circuit is built around 120V, this unit will not be the direct match. For an industrial panel that runs on 24V control, it is the one to choose, and the DIN rail mounting base makes installation straightforward.
Final Choice by Use Case
Choose the HIATSU Motor Contactor when you're replacing a contactor in an air conditioner or HVAC system and want a direct replacement part. Choose the Shopcorp Contactor when your switching needs center on motor and lighting loads in an industrial control setup. Consider the coil voltage and mounting style of your existing setup before making your selection. Both have their place, so match the contactor to the job.
