ABB TVOC-2-240 1SFA664001R1001
Product Overview
The ABB TVOC-2-240, order code 1SFA664001R1001, is the main controller unit of ABB Arc Guard System™, a high-speed arc flash protection monitor designed for low voltage and medium voltage switchgear cabinets. It detects arc flash via optical fiber sensors. Once arc light is captured, the unit outputs trip signal to circuit breaker within 1 ms, rapidly cutting power to minimize explosion energy, protect field operators and electrical equipment, and reduce production downtime. TVOC-2-240 is SIL 2 functional safety certified, equipped with HMI panel and door mounting accessories. It supports expansion modules to increase optical detector channels, widely adopted in power distribution and industrial power cabinet safety retrofit projects.
