Opening a control panel can be a guessing game. The two contactors in this head-to-head sit at opposite ends of the relays, contactors, and industrial switches spectrum: one is a compact 110V coil starter relay for smaller circuits, and the other is a 24V coil, 4-pole normally closed contactor for heavier motor and lighting duty. The real decision isn't just price - it's matching coil voltage, pole count, and load class to the circuit you are controlling.
Quick verdict
Choose the 4 Pole 60A NC Contactor when you need four-pole normally closed switching, silent operation, and DIN rail mounting for motor, lighting, and HVAC applications. Choose the Modern Power AC Contactor when you need an 18A starter relay with built-in auxiliary contacts for momentary-button control and a compact footprint. The two units solve different problems: one is a 24V coil contactor for larger loads, and the other is a 110V coil starter relay for lighter circuits.
Comparison
| Feature | 4 Pole 60A NC Contactor | Modern Power AC Contactor |
|---|---|---|
| Price | USD 99.95 | USD 16.91 |
| Coil voltage | 24V | AC110V |
| Contact layout | 4-pole, normally closed | Starter relay with built-in auxiliary contacts |
| Typical use | Motor, lighting, HVAC | Smaller motor starting, main power switching |
Where each product wins
The 4 Pole 60A NC Contactor wins whenever the panel needs four-pole normally closed switching, low-voltage coil control, and a DIN-rail form factor. It is the one to reach for when motors, lighting, compressors, and HVAC equipment sit on the load side. Its silent operation makes it easier to work near in a control cabinet.
The Modern Power AC Contactor wins on cost, size, and simplicity. Its 18A working current is enough for smaller motors, and the built-in auxiliary contacts make it easy to wire simple start-stop stations with momentary push buttons. For a lightweight, compact panel, it is the more practical choice.
Product notes
4 Pole 60A NC Contactor 24V Coil IEC 400V for Motor & Lighting DIN Rail Mount
The 4 Pole 60A NC Contactor is the higher-current side of this matchup. Its 24V coil lets low-voltage control circuits switch a much larger load, while the normally closed four-pole contact arrangement provides independent switching on four circuits. With motor, lighting, compressor, and HVAC applications in mind, it also offers silent operation and a 35mm DIN rail mount for standard control panels. That makes it a serious candidate when you are building an industrial-style panel. The limitation is the price tag: at $99.95 it costs a full $83.04 more than the Modern Power unit, so it only makes sense when you genuinely need the four-pole, 24V coil capability and the higher current class. For a simple 18A switching job, that extra spend is hard to justify.
Modern Power AC Contactor AC110V 50/60Hz Motor Starter Relay 18A Working Current
The Modern Power AC Contactor is the low-cost, space-saving side of this head-to-head. Its AC110V 50/60Hz coil matches 110V control circuits, and the 18A working current is a realistic fit for smaller motors, main power switching, and straightforward starter relay duties. The lightweight plastic die-cast body keeps the unit easy to handle, and the built-in auxiliary contacts are designed to work with momentary push buttons, which simplifies simple control stations. The trade-off is capacity: at 18A, this is not the contactor for four-pole high-current motor or lighting branch circuits; it is aimed at lighter loads where budget matters. For that role, the $16.91 price is the headline reason to choose it.
Final choice by use case
Pick the 4 Pole 60A NC Contactor for a 24V coil control panel, four-pole normally closed switching, DIN rail mounting, and motor/lighting/HVAC loads that demand a larger-load contactor. Pick the Modern Power AC Contactor for an AC110V control circuit, 18A loads, and a compact starter relay with auxiliary contacts. Both are new contactors, but they solve different problems in the relays, contactors, and industrial switches family.
