1SBN082413R2000 ABB BEY 26-2 Connection Set for Star-Delta Starters A16-A26 3-Pole Contactors

Why Choose the ABB 1SBN082413R2000 BEY26-2 Connection Set?

The ABB 1SBN082413R2000, model BEY26-2, is a purpose-designed star-delta connection set for ABB block contactors. It provides the main power connections required between the line, delta and star contactors in a star-delta motor starter, helping simplify assembly and reduce the amount of individual wiring required inside industrial control panels.

Designed for use with ABB's classic A and AL contactor range, the BEY26-2 is intended for star-delta combinations using an A/AL26 line and delta contactor with an A/AL16 star contactor. It can also be used in arrangements incorporating a compatible VM/VE5-1 mechanical interlock, providing a convenient connection solution for coordinated ABB contactor assemblies.

The connection set incorporates the conductors required for the line-to-delta phase connections, delta-to-star connections and the star point. Its combination of insulated solid copper bars and insulated flexible copper conductors provides a compact alternative to fabricating individual power links, helping improve consistency and simplify installation of star-delta starter assemblies.

Simplified Star-Delta Motor Starter Connections

Star-delta starters reduce motor starting current by initially connecting the motor windings in star before changing over to delta for normal operation. Building this type of starter requires coordinated electrical connections between the line, star and delta contactors, making correct conductor arrangement an important part of the assembly.

The ABB BEY26-2 simplifies this process by providing dedicated prefabricated connections for the intended ABB contactor combination. Using a manufacturer-designed connection set reduces the need to fabricate individual links and helps create a compact, consistent and serviceable star-delta starter installation.

Typical Applications

• Star-delta motor starter assemblies.
• Industrial motor control centres.
• Electrical control panels and switchgear.
• Pump and fan motor starters.
• Conveyor and material handling systems.
• Industrial machinery control panels.
• OEM machine building and automation systems.
• Replacement and maintenance of compatible ABB star-delta assemblies.
