072817 - Miller 24VAC DPDT Enclosed Relay 20A 8-Pin Flange Mount

Reliable Control for Miller Welding Equipment

The Miller 072817 Relay is a critical component designed to maintain the operational integrity of your Miller welding machinery. As a genuine OEM part, this enclosed relay is engineered to meet the exact specifications required by Miller Electric for their high-performance equipment. Relays play a pivotal role in the internal electronics of welding power sources, acting as the bridge between low-voltage control signals and higher-power circuits. This specific unit features a 24VAC coil, a standard voltage for control logic in many industrial machines, ensuring seamless integration with your existing system's architecture.

Featuring a Double Pole Double Throw (DPDT) configuration, this relay offers versatile switching capabilities, allowing it to control two independent circuits simultaneously. This is particularly useful in complex welding systems where multiple subsystems—such as cooling fans, gas solenoids, or wire feed motors—need to be activated or deactivated in unison. The relay is rated for 20 Amps at 120VAC, providing ample capacity to handle substantial electrical loads without overheating or failing prematurely. The robust contact rating ensures longevity even under the frequent cycling typical of busy fabrication environments.

Durability is a key focus of the Miller 072817. The "Encl" in its description stands for enclosed, meaning the delicate internal contacts and armature are housed within a protective shell. In a welding shop, the air is often filled with conductive dust, metal grinding particles, and fumes. An enclosed relay prevents these contaminants from fouling the contacts, which could otherwise lead to arcing, increased resistance, or complete failure. The 8-pin design with flange mounting ensures that the relay remains securely fastened within the machine chassis, resistant to the vibrations caused by transformers and cooling systems. When replacing internal components, choosing genuine Miller parts like the 072817 guarantees fitment, safety, and performance.
