ABB motor starting solution introduces tool-free, push-in wiring
Zurich, Switzerland-based ABB says it has launched the industry’s first range of motor starting solutions with a Pushin Spring technology that makes faultfree wiring easier than ever. The toolfree connection speeds-up wiring work and provides a vibration-resistant connection that makes continuous operation more reliable.
The 2-in-1 design combines the advantages of both Push-in and Spring technology in a single terminal.
In Push-in mode, rigid cables or cables with ferrules can be connected toolfree. The operator just pushes them into the cable holes, cutting wiring time by up to 50% compared to a conventional spring solution and making installation significantly easier. The self-tightening terminals help eliminate wiring errors and mean there is no need for routine re-tightening work.
Spring mode makes it simpler to insert small cross-section cables or cables without ferrules, and also makes unwiring the motor starters significantly faster. The operator simply inserts a screwdriver into the clearly marked holes before inserting the cable. This one-step process makes ABB’s solution easier to use and less prone to damage than conventional spring mechanisms.
The solution’s clearly marked terminals, an intuitive cable insertion concept and zero torque connections mean that no special training is required. With easy front access and 90-deg. insertion angles for cables and screwdrivers, automated robot assembly is also possible.
The Push-in solution is available with a rated operational current of up to 32 A for the manual motor starter MS132-K and up to 38 A (50 A AC-1) with the AF.K contactor. A wide range of auxiliaries, mounting kits and accessories compatible with the screw range will be available. 100% tool-free mount and dismount connecting kits significantly reduce installation time. Operators can connect devices for direct on-line, reversing and star-delta starters without using any wires. It is shock and vibration resistant.
