ABB Object 1SCA022761R2800 Rotary Switch 20A 4-Position

ABB Object Rotary Switch — 20A 4-Position for Motor Reversing and Selector Control in Saudi Industrial Panels

The ABB Object series rotary switch (part 1SCA022761R2800) provides 4-position manually-operated switching for motor reversing, selector control, and test/isolation functions in Saudi industrial control panels. Object switches are widely used for LOCAL/OFF/REMOTE selector stations on pump panels and conveyor control stations in Jeddah, Dammam, and Riyadh industrial facilities.

Saudi Aramco instrumentation specifications require LOCAL/OFF/REMOTE selector switches on all motor-driven equipment — Object rotary switches are the standard choice for selector stations in Saudi Aramco plant MCC panels and for motor reverse switching on crane and conveyor drives.

Key Features

4-Position Operation: OFF-L1-L2-L3 or custom sequence — standard for motor reversing and LOCAL/REMOTE selector functions.

20A AC-3 Rating: Handles motor reversing contactor switching up to 5.5kW without intermediate relay.

Padlockable Off Position: Mechanical padlock prevents unauthorized energization — mandatory for Saudi LOTO (Lockout/Tagout) compliance in petrochemical facilities.

Behind-Panel Mount: 22.5mm round shaft mount — standard cutout for Saudi panel builders.
