The ABB Low Voltage Products division has released TVOC-2, a new generation of its proprietary Arc Guard System that protects electrical equipment from dangerous electrical arc flashes. TVOC-2 features numerous upgrades and new functions to provide superior arch flash protection, detecting faults in low and medium voltage switchgear and disconnecting the power provided to the arc within 30 to 50 milliseconds. An arc flash will typically trip a circuit breaker in approximately one second, enough time for the arc to destroy the switchgear and kill or seriously injure a person. TVOC-2 is now UL listed.
