Choosing a contactor for a motor control job usually comes down to matching the voltage your control circuit supplies with the current your load draws. In the relays, contactors, and industrial switches aisle, two new options take very different approaches to that match. One is a simple motor starter relay. The other is a motor contactor with different electrical requirements. The right move is to decide which fit matters more before you buy.
Quick verdict
If you want a direct path to a motor starter relay, the Modern Power AC Contactor at USD 16.91 is the sensible pick. If you need the CA7-85 motor contactor, the Sprecher + Schuh at USD 289.99 is the one to buy.

Where each product wins
Modern Power AC Contactor wins when you want a straightforward motor starter relay and the load is within range. Sprecher + Schuh CA7-85 wins when you need a contactor for three-phase motor control.
Product notes
Modern Power AC Contactor AC110V 50/60Hz Motor Starter Relay 18A Working Current
Start with the 18A working current because that is the load limit that matters most. The plastic body is impact-resistant and scratch-resistant, so it is suited to tight enclosures. It also includes built-in auxiliary contacts, which makes it easy to pair with momentary buttons in a simple motor starter circuit. For a 110V AC control circuit, the coil voltage matches directly. The limitation is the same number: if your motor pulls more than 18A, this contactor falls out of the right range. If the load fits and the control circuit is 110V, the Modern Power AC Contactor is a straightforward and compact way to get a motor starter or main power switch running.
Sprecher + Schuh Contactor CA7-85-10-220W 220v coil Brand new Motor contactor
The CA7-85-10-220W is built around a 220V coil, with a rated coil range of 200-220V at 50/60Hz, so it belongs in a control circuit with that voltage. It includes a side-mounted normally open auxiliary contact and can be base mounted or snapped onto a 35mm DIN rail, giving you placement flexibility in an industrial panel. It is also suited to safety IEC and standard IEC contactor use, which makes it a sensible fit in installations that follow those conventions. The main catch is the coil voltage: if your control circuit supplies 110V, the 220V coil is not a direct match. For a three-phase motor control job with 220V control power, the Sprecher + Schuh CA7-85 is the one to pick.
Final choice by use case
For a direct motor-starter job, pick the Modern Power AC Contactor. For a CA7-85 contactor job, pick the Sprecher + Schuh.
