FAQs
The ABB 7TBA008940R0093 is a single pole, single throw thumbwheel switch with an On-Off function in a black finish and packaged as a two-pack. It is designed for panel mounting in low-voltage control circuits and pairs with standard wiring practices used for ABB components. For installation, verify enclosure clearance, wiring gauge compatibility with 6A-125VAC/3A-250VAC loads, and refer to the SWLC11-OF-BK datasheet for detailed terminal arrangements.
This switch is rated for 6A at 125VAC, 3A at 250VAC, and 3A at 125V. When sizing, compare your control load to these ratings with a safety margin to account for inrush and switching transients. For lamp or instrumentation circuits within these limits, it provides reliable actuation. Use the 2-pack to ensure backups or multi-point control without increasing footprint.
Yes. The 7TBA008940R0093 is designed for panel-level control in automation environments. Its single-pole, single-throw configuration and ON-OFF function are well-suited for discrete setting controls in compact control panels and instrumentation. The two-pack packaging supports consistent replacement and maintenance planning, and its compatibility with ABB components helps ensure integration across ABB-based systems.
Key certifications to verify on the datasheet for this switch include general safety approvals (such as CE and UL/CSA where applicable) and any IP-related ratings relevant to the installation environment. The product references a Data Sheet SWLC11-OF-BK and notes WEEE category as Product Not in WEEE Scope. Always confirm certification alignment with your regional regulatory requirements and application conditions.
The thumbwheel switch offers a mechanical, field-serviceable action with straightforward replacement, which reduces maintenance downtime. In rugged environments, ensure the actuator and housing remain clean and free of contaminants that could impede rotation. Regular inspection of the two-pack stock and confirmation of electrical ratings alignment with the controlled load will help maximize lifespan and reliability in ongoing operations.
