SIL-2 electrical arc flash guards

TVOC-2 Arc Guard Systems are new to protect electrical equipment from dangerous arc flashes.

The new generation model carries a SIL-2 functional safety rating. It achieves required standard to protect both humans and expensive switchgear equipment.

TVOC-2 features many upgrades and new functions for "superior arc flash protection," declares its manufacturer. These include ability to detect faults in low and medium-voltage switchgears and disconnecting power provided to the arc - within 30 to 50 ms - preventing serious personnel injury or equipment damage.

Without Arc Guard system, an arc flash will typically trip a circuit breaker in approximately 1 sec. This is enough time for the arc to destroy a switchgear and kill or seriously injure a worker.

TVOC-2 is now UL listed. When installed with its maker's Emax circuit breakers, it carries a functional safety rating of SIL-2 as certified by TÜV Rheinland.
