Features:
- ABB article 1SFA664001R1001 identifies TVOC-2-240, an arc monitor supplied with one HMI and door-mounting accessories. ABB specifies 100–240 V AC or 100–250 V DC supply and ten optical detector inputs on the base unit.
- Confirm the exact article, supply class, detector count and locations, HMI, current-sensing interlock, trip outputs, breaker scheme and zone logic.
- Use it in the documented low-voltage switchgear arc-protection scheme only after every detector and trip path is mapped.
1SFA664001R1001 TVOC-2-240 is selected from the complete manufacturer identity and receiving-system evidence. Isolate all supplies, install optical detectors with clear sight of protected zones, route fibers within bend limits and verify HMI/trip wiring. Use the approved commissioning method to prove each detector channel, current interlock, trip relay, breaker operation, HMI indication and alarm reset.

Assign every optical detector to its switchgear zone and documented trip path.
Verify current sensing, breaker selection and any permissive logic used to prevent unintended trips.
Prove detector input, relay output, breaker opening, indication and reset for each protected zone.
