£36.68
The ABB 1SCA163353R1001 OT16G1-3BQ is a compact 3-pole OT Plus switch-disconnector rated at 16 A, designed for safe isolation and switching of low-voltage electrical circuits. Supplied complete with a padlockable direct-mounted black handle, it is suitable for both base mounting and DIN rail installation, making it ideal for industrial control panels, machinery and power distribution systems.
Engineered in accordance with IEC 60947-3, the OT16G1-3BQ provides dependable load isolation with a rated operational voltage of up to 800 V AC. Its spring terminals allow fast, secure wiring while the compact G1 frame minimises panel space requirements without compromising performance.
Manufactured by ABB, the OT Plus range is renowned for its mechanical durability, operational reliability and wide accessory compatibility, making this switch-disconnector an excellent choice for OEM machine builders, panel manufacturers and maintenance engineers.
The OT16G1-3BQ is designed to safely isolate electrical circuits under load while maintaining low contact resistance and long mechanical life. Its three-pole configuration makes it suitable for isolating three-phase supplies used in industrial machinery, HVAC systems and distribution panels.
The supplied padlockable direct handle supports lockout/tagout procedures, helping prevent accidental energisation during maintenance. Spring terminals reduce installation time while ensuring secure cable retention, making the switch suitable for both new installations and retrofit projects.
