ABB Thermal Overload Relay TF42-5.7

The TF42-5.7 thermal overload relay from ABB is a reliable protection device specifically designed for use in electrical drive systems. It offers precise monitoring of motor performance and protects against overload by interrupting the current flow when critical values are reached. With a full-load current (FLC) motor rating of 4.2 to 5.7 A and a contact rated current of 5.7 A, this relay is ideal for various industrial applications. It is mounted directly on the contactor, allowing for easy installation. The relay features a contact configuration of 3P and provides both a normally closed and a normally open contact, enabling flexible integration into existing systems. Additionally, the relay can be reset both automatically and manually, making it user-friendly.

• FLC motor rating of 4.2 to 5.7 A
• Automatic and manual reset type
• Contact configuration: 3P with 1 normally closed and 1 normally open contact
• Power consumption of only 2 W.
