ABB Thermal Overload Relay, 690V AC/DC Voltage Rating, 3 Pole - AF Series - TF42-1.7
Choose this thermal overload relay from ABB to quickly switch electrical loads in your circuit. The two auxiliary contacts turn appliances on and off to protect against overheating and increase motor lifespan. The unit has a power rating of 2W, so it can handle demanding applications. The stop and test functions offer reliable protection from phase failure, while automatic and manual reset methods support safe working.
Features & Benefits
• Compact dimensions of 88.3 (L) x 45 (W) x 70.5mm (D) to save space
• Operating temperature between -25°C to +60°C for safe industrial use
• Energy efficient with a normal state configuration of 1NO+1NC
• Contact current rating of 1.7A for wide compatibility
• Full load current motor rating of 1.3 to 1.7A for versatility Applications • Manufacturing equipment
• Production lines
• Factory automation How do I install this overload relay? The unit has screw-type terminals for quick installation and secure connections. How does a thermal overload relay work? Thermal overload relays like this one use a bi-metallic plate to detect excessive current when it passes through the heating element. If there's a risk of overload, the plate twists out of shape and interrupts the power supply.
