Product details

It carries UL and CSA listings, so it's accepted in North American panel builds without a separate evaluation.

The TMF trip block is fixed at 250 A, not adjustable. That simplifies ordering — one code, one trip setting — but also means you cannot dial it down for a smaller load. Make sure the continuous load stays under 250 A; the breaker is sized for the full rating.
