The TF96-68 thermal overload relay is an economic electromechanical protection device for the main circuit. It offers reliable and fast protection for motors in the event of overload or phase failure. The device has trip class 10. Further features are the temperature compensation, trip contact (NC), signal contact (NO), automatic- or manual reset selectable, trip-free mechanism, STOP function and a trip indication. The overload relays are connected directly to the block contactors. Single mounting kits are available as accessory.
The TF96-96 thermal overload relay is an economic electromechanical protection device for the main circuit. It offers reliable and fast protection for motors in the event of overload or phase failure. The device has trip class 10. Further features are the temperature compensation, trip contact (NC), signal contact (NO), automatic- or manual reset selectable, trip-free mechanism, STOP function and a trip indication. The overload relays are connected directly to the block contactors. Single mounting kits are available as accessory.
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 tripclass 10.The thermal overload relays are three pole relays with bimetal tripping elements. The motor current flowsthrough the bimetal tripping elements and heats them directly and indirectly. In case of an overload (overcurrent), the bimetal elements bent as a result of the heating. This leads to a release of the relay and achange of the contacts switching position (95-96 / 97-98).– Manual or automatic reset selectable– Phase loss sensitive acc. to IEC/EN 60947-4-1– TEST and STOP function – Trip indication on the front– Temperature compensation– Suitable for three- and single-phase applications– designed in accordance to the applicable parts of IEC 60077 standard– shocks and vibration withstand conforming to IEC 61373 (category 1, class B)– usable according to European fire and smoke safety standard EN 45545-2
The EF96 is an self-supplied electronic overload relay, which means no extra external supply is needed. It offers reliable and fast protection for motors in the event of overload or phase failure. Easy to use like a thermal overload relay and compatible with standard motor applications, the electronic overload relay is convincing, above all, due to its wide setting range, high accuracy, high operational temperature range and the possibility to select a trip class (10E, 20E, 30E). Further features are the temperature compensation, trip contact (NC), signal contact (NO), automatic- or manual reset selectable, trip-free mechanism, STOP- and Test function and a trip indication. The overload relays are connected directly to the contactors. Single mounting kits are available as accessory. The EF65, EF96 and EF146have ATEX and IECEx certification 1)1) ATEX is valid for products produced from week 42, 2014.IECEx is valid for products produced from week 15, 2017.
