When you're building or repairing a control panel, one of the first decisions you'll face is whether to reach for a relay or a contactor. Both are designed to switch electrical circuits, but they serve different current ranges and operating voltages. In the relays, contactors, and industrial switches category, the INDUSTRIAL SPARE AC250V6A RELAY and the Modern Power AC Contactor AC110V 50/60Hz Motor Starter Relay 18A are two compact options that sit close in price but far apart in capability. Here's how to decide which one belongs in your panel.
Quick Verdict
If your circuit only needs to switch light loads and you prefer a simple relay, the INDUSTRIAL SPARE AC250V6A RELAY is the no-fuss solution. If you're driving a motor starter or need more switching muscle, the Modern Power AC Contactor with its higher working current is the clear choice.
Comparison Table
| Feature | INDUSTRIAL SPARE AC250V6A RELAY | Modern Power AC Contactor AC110V 50/60Hz Motor Starter Relay 18A |
|---|---|---|
| Price | USD 15.00 | USD 16.91 |
| Working voltage | 250V AC | 110V AC |
| Current rating | 6A | 18A |
| Condition | New - Open box | New |
| Product type | Relay | Power AC Contactor |
Where Each Wins
The INDUSTRIAL SPARE relay wins for simple, low-current switching tasks that fit within a 6A envelope and a 250V AC system. The Modern Power contactor wins for motor-starter duty and heavier loads, thanks to its 18A working current and auxiliary contacts for control logic.
Product Notes
INDUSTRIAL SPARE AC250V6A RELAY
The INDUSTRIAL SPARE AC250V6A RELAY is a straightforward relay for light-duty jobs. Its 6A rating at 250V AC positions it as a spare relay for control circuits, and the new open-box condition means the unit hasn't been in active use. Choose this when you need a simple relay with a modest current envelope and you don't require contactor-level switching. The limitation is that 6A is a firm ceiling, so large motors and heavy loads are out of its reach. For more demanding tasks, you'd have to step up to a contactor. For small control duties, though, this relay offers the essential function you need without extra complexity.
Modern Power AC Contactor AC110V 50/60Hz Motor Starter Relay 18A
The Modern Power AC Contactor steps in for heavier switching. With an 18A working current and a 110V coil, it handles motor-starter duty and larger loads that would overwhelm a 6A relay. Its plastic housing is built with a die-casting process for impact resistance, and it includes built-in auxiliary contacts that work with momentary buttons, giving you more control options. This is the one to pick when your project demands 18A of switching capacity or you're assembling a proper motor starter. The trade-off is that it's a more specialized piece of equipment; if your circuit only needs a simple relay, the contactor's extra capacity and control features are more than you need. For higher-current work, this contactor delivers the switching capability you're looking for.
Final Choice by Use Case
The decision comes down to the load you're switching. If your circuit draws only light current and matches the relay's rating, the INDUSTRIAL SPARE AC250V6A RELAY is the practical answer. If you're building a motor starter or need higher switching capacity, the Modern Power AC Contactor is the right tool. Match the device to the job, and you'll have a control panel that switches safely and reliably.
