BOM cost is a little high at about $8/channel in qty 1 from Digikey (so assume 1/10th that or less at any decent scale). They have capacitors to set the allowable overcurrent time. One of the circuits I built at work hard limits at 180A and is intended for 60A continuous. Consumes a little less than a square inch.

Part numbers and links please.
