ABB TF42 Thermal Overload Relay 1NO + 1NC, 7.6 → 10 A F.L.C, 10 A Contact Rating, 2 W, 3P, AF Range

Stop surges in their tracks with this electromechanical thermal overload relay from ABB. If there's an overload, an internal bimetallic strip reacts to the heat by bending. This breaks the circuit and shuts down machinery in a snap to keep motors protected from phase failures. A front-facing screw means it's easy to adjust the current setting between 0.74 and 1A to suit your equipment. For handy troubleshooting, this relay has an LED on the front that clearly indicates its status.

• Broad operating temperature range between -25°C and +60°C so it's reliable in harsh conditions
• Screw terminals mean it's simple to install without specialist tools
• Compact dimensions of 45 (W) x 88.3 (H) x 70.5mm (D) for installation in tight spots
• NC and NO contacts mean it's versatile
• IP20 rating means it's touch-proof and safe to handle

• Manufacturing equipment
• Automated systems
• Mining industry

You can easily attach this relay to an AF-series contactor (237-4888) using a mounting kit (231-8956).

You can select either manual or automatic reset using the blue button on the front.
