Ihold
Hold Current:Maximum current device will not trip in 25℃ still air.
Itrip
Trip current:Minimum current at which the device will always trip in 25℃ still air
Vmax
Maximum operating volatge device can withstand without damage at ratde current(imax).
Imax
Maximum fault current device can withstand without damage at rated voltage(Vmax).
Pd
Typical power dissipatde from device when in the tripped state in 25℃ still air.
Rmin/max
Minimum/Maximum device resistance prior to tripping at 25℃.
R1max
Maximum resistance of device at 25℃ measured one hour after trippde tripping.
*CAUTION
Operation beyond the specified rating may result in damage and possible arcing.
