To control the power feed to your circuit, opt for this contactor from Eaton. When its electromagnetic coil is energised, the contacts open or close to make or break a connected circuit. With a contact rating of 20A, this device can handle the rigours of high-power electrical systems. You'll typically find it in energy solutions such as solar panels or wind turbines. A closing delay from 15 to 21ms and an opening delay between 9 and 18ms means you can trust it switches power to your circuit in a flash.

• Mounting position is adjustable by up to 180° for flexible assembly
• Tolerates up to 5000 operations per hour, so you get reliable performance
• Mechanical shock resistance of 10g to withstand heavy-duty settings

This unit has screw terminals, so you can link wires with just a screwdriver and achieve solid connections that won't wobble loose under vibration.

Thanks to its mechanical service life of 20 million operations, you can depend on the contactor for long-term use with minimal risk of downtime.
