New ABB motor starting solution introduces tool-free, push-in wiring

ABB is launching the industry’s first range of motor starting solutions with a Push-in Spring technology that makes fault-free wiring easier than ever. The innovative tool-free connection concept speeds up wiring work and provides a vibration-resistant connection that makes continuous operation more reliable. 

ABB’s intuitive 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 tool-free. The operator just pushes them into the cable holes, cutting wiring time by up to 50 percent in comparison 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° insertion angles for cables and screwdrivers, automated robot assembly is also possible. 

Massimiliano Cifalitti, global product group manager for ABB’s Motor Starting and Safety business, said: “The launch of this new motor starting solution with Push-In Spring terminals is another significant step forward by ABB. This is a smart way for OEMs, panel builders and machine builders to speed up their installation work and improve reliability. The secure, vibration-resistant connection provided by ABB’s new range also means there is no need to retighten connection cables during the product’s lifetime.”

The new 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 that are even compatible with the screw range will be available. 100 percent 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.

“ABB’s clever design creates a robust electrical contact that you can count on in even the harshest operating environments,” said Massimiliano. “It is shock and vibration resistant and, with self-tightening terminals, ABB’s Push-in Spring solution spells an end to routine re-tightening tasks. ABB’s innovative motor starting solution provides meaningful productivity gains and total peace of mind.”
