Choosing between a power relay and a reversing motor starter in the relays, contactors, and industrial switches aisle means matching the component to the job, not just the price. The Struthers-Dunn 219XBX69P-115/125VDC Industrial Automation Power Relay and the AB 100-C09*10 Reversing motor starter Contactor 1.6/5A overload relay 120V Coil both control electrical loads, but they are built for different control functions.
Quick Verdict
Choose the Struthers-Dunn when you need a power relay for a commercial or industrial control panel. Choose the AB 100-C09 when you need a reversing motor starter with overload protection. The right pick comes down to coil voltage and whether motor reversal is part of the job.
At a Glance
| Feature | Struthers-Dunn 219XBX69P | AB 100-C09\*10 |
| Price | USD 319.99 | USD 74.99 |
| Type | Power Relay | Reversing motor starter contactor |

The price spread runs from USD 74.99 to USD 319.99, so the AB costs USD 245.00 less than the Struthers-Dunn.
Where Each Product Wins
Struthers-Dunn 219XBX69P wins if...
You need a power relay for a commercial or industrial control panel and your control circuit runs on 115/125VDC. The Struthers-Dunn is built for that kind of permanent panel application.
AB 100-C09\*10 wins if...
You need to reverse a motor and want overload protection, and your control circuit uses a 120V coil. The AB reversing starter includes the overload relay and connector wire, making it a complete reversing package.
Product Notes
Struthers-Dunn 219XBX69P-115/125VDC Industrial Automation Power Relay
The Struthers-Dunn 219XBX69P is a power relay built for commercial, control equipment panels, and industrial applications. Because it is a dedicated relay, it can handle general switching inside a control system rather than being limited to motor-starting duty. The strongest reason to choose it is that intended role: a panel component designed for continuous automation and control equipment. The trade-off is that it costs noticeably more than the AB reversing starter, and it does not provide motor reversal or an overload relay on its own. If your application is simply switching loads in a control panel, this relay is a clean fit; if you need motor reversing, you would pair it with additional components.
AB 100-C09\*10 Reversing motor starter Contactor 1.6/5A overload relay 120V Coil
The AB 100-C09\*10 is a reversing motor starter contactor with a 1.6/5A overload relay. The strongest reason to choose it is the price: at USD 74.99, it is far less expensive than the Struthers-Dunn relay. It also includes the overload relay and the connector wire between contactors, so the reversing starter package is more complete. The limitation is the overload relay's current rating; it is sized for 1.6/5A, which means it is appropriate for motors drawing current in that range. A larger motor would need a different overload relay or starter. If your application is motor reversal, the AB unit is a direct fit for the job.
Final Choice by Use Case
By use case: choose the Struthers-Dunn when the task is general power switching or relay logic in a control panel. Choose the AB 100-C09 when the task is reversing a motor with overload protection. The deciding factors are your coil voltage and whether you need motor reversal.
