- Product overview
An arc flash advances at a speed of 300 m/s in a switchgear, burning any material on its way. The arc keeps burning as long as it is supplied with power. The TNT-APS arc light integrated protection system (time of removingfailure is 60-70 ms) realizes 60ms actuation time compares with that of traditionalprotection actuation , which effectively restricts the arc light failure in the initial stage
