ARC Resistance to Ignition Tester
High Current ARC Resistance to Ignition Test Apparatus of UL746A
Product details:Model ZLT-DQY
To check a fire enclosure of the material that is located less than 13 mm through air from arcing parts such as unenclosed commutators and unenclosed switch contacts,according to UL746A,UL1082.
1 circuit for high current arcing test,the current is 33 A at a power factor of 0,5,
1 stationary electrode consists of a 3,5 mm diameter solid copper conductor having a 302 chisel point,
1 movable electrode consists of 3 mm diameter stainless steel rod with a symmetrical conical point having a total angle of 602 and is capable of being moved along its own axis,
1 motor with a separation speed of 254 mm/s±25 mm/s, to produce a series of arcs at a rate of approximately 40 arcs/min,
1 set 6 digit counter to records the arcs.
Power supply:380V50Hz,other voltages.
