Electrical Characteristics

Part Number Marking I hold (A) I trip (A) V max (Vdc) I max (A) P d typ. (W) Maximum Time-To-Trip Resistance Agency Approvals Current (A) Time (Sec.) R min (Ω) R 1max (Ω) I hold = Hold current: maximum current device will pass without tripping in 20°C still air. I trip = Trip current: minimum current at which the device will trip in 20°C still air. V max = Maximum voltage device can withstand without damage at rated current (I max) I max = Maximum fault current device can withstand without damage at rated voltage (Vmax) P d = Power dissipated from device when in the tripped state at 20°C still air. R min = Minimum resistance of device in initial (un-soldered) state. R 1max = Maximum resistance of de vice at 20°C measured one hour after tripping or reflow soldering of 260°C for 20 sec. Caution: Operation beyond the specified rating may result in damage and possible arcing and flame. Note: *1812L350 Typical Time-to-Trip is 50A at 0.013-0.020 seconds and meets the 8A at 5 seconds maximum Time-to-Trip requirement. **1812L350 R1min=0.015ohm (resistance range 0.015-0.025ohm).
