What the ratings mean for your application
The LC1G3304LSEN: The 330 A Ith at AC-3 duty defines its motor-switching capability; pair it with a 400 A aM or 250 A aM fuse per the associated fuse rating list. Average impedance of 0.000144 ohm per pole keeps voltage drop low at rated current. The built-in bidirectional peak limiting coil technology allows direct connection to a 200-500 V AC or DC source without external suppression — watch the dropout window: 0.1 Uc max to 0.45 Uc min at 60°C, so a well-regulated supply is expected. Mechanical durability of 8 Mcycles suits high-cycling applications like conveyor or HVAC staging.
