ABB Solution for management and protection of electric motors

2019: Announcement of the solution for management and protection of electric motors

On June 24, 2019 the ABB company presented the solution, the first at the market, for management and protection of electric motors with technology of vtychny installation which provides simple and faultless connection of any conductors. The concept of connection without use of tools accelerates electric installation work and provides stable and reliable connection on all service life of a product even in the conditions of the increased vibrations.

According to the company, using this technology of vtychny installation, it is possible to perform connection of conductors without use of tools, to increase project implementation speed and to provide the reliable connection which is not requiring service during all service life.

The solution 2 in 1 of ABB integrates advantages of vtychny and spring technologies in one jumper. In the mode of the vtychny jumper for connection of tough conductors or flexible conductors with a tip it is not required to use any tools – the construction electrician needs just to insert conductors into cable openings that considerably facilitates connection process. Self-tightening spring jumpers help to avoid an error at installation and exclude need for a broach and carrying out other regular works on service.

The mode of the spring jumper, in turn, simplifies process of connection of flexible conductors or cables of small section and considerably reduces time necessary for installation of the solution – it is enough to insert the screw-driver into accurately designated openings then it is possible to insert a cable into the jumper only. Unlike classical spring jumpers this technology of connection does the solution of ABB to simpler in use and to less subject potential damages.

Accurately marked jumpers, intuitive technology of connection of a cable exclude need special personnel trainings. The solution with technology of vtychny installation assumes connection of all cables at an angle 90 ° to a frontal surface. Access to jumpers from the face promotes convenient and reliable connections of a cable and also provides a possibility of auto editing of conductors.

The range of the equipment of a series is provided by time cut-outs for protection of MS132.K electric motors on rated currents up to 32 A and contactors of AF.K on currents up to 38 A (50 A AC-1). The wide range of the mounting kits, connecting adapters and accessories compatible to standard devices to screw jumpers is available to the equipment. When using connecting adapters there is an opportunity to implement solutions for direct start-up, reverse start-up and launch of the engine according to the scheme "star triangle" without application of outer conductors. Installation and dismantling of connecting adapters does not require absolutely any tools that considerably reduces time for assembly.
