Appleton Industrial Plugs & Receptacles

RSP Supply carries a full line of Appleton industrial plugs and receptacles engineered for safe, durable, and code-compliant power connections in heavy-duty and hazardous locations. Designed for industries where reliability and safety are paramount, Appleton products ensure consistent electrical performance in the harshest conditions.

Constructed with rugged housings, corrosion-resistant materials, and precision-machined contacts, Appleton plugs and receptacles maintain dependable connections in environments exposed to moisture, chemicals, vibration, or temperature extremes. These devices are widely used in manufacturing plants, oil and gas facilities, refineries, and chemical processing sites, where uninterrupted power and operator safety are critical. Many Appleton models are explosion-proof or watertight, meeting NEC, UL, and CSA standards for hazardous location use. Mechanical interlocks prevent accidental disconnection under load, minimizing arc flash risks and equipment damage. Their secure locking mechanisms, color-coded voltage options, and broad amperage ratings make them ideal for powering heavy-duty motors, welders, and portable machinery across industrial applications.
