6/2 ABB MOTOR CONTROL AND PROTECTION FOR ROLLING STOCK APPLICATIONS

—
TF42-B thermal overload relays – 0.10 to 38.0 A

Ordering details

The TF42-B thermal overload relays are economic electromechanical protection devices for the
main circuit, complying with the latest railway rolling stock standards and allowing installation in
passengers or driver cabins for trains frequently operating tunnels or undergrounds.
They offer a reliable protection for motors in the event of overload or phase failure. The devices
have trip class 10.
The thermal overload relays are three pole relays with bimetal tripping elements. The motor cur-
2CDC231001V0016 rent flows through the bimetal tripping elements and heats them directly and indirectly. In case
of an overload (over current), the bimetal elements bent as a result of the heating. This leads to a
release of the relay and a change of the contacts switching position (95-96 / 97-98).
