Product details

The ABB 1SDA068084R1 is an XT4N 160 TMA distribution circuit breaker, three-pole, with a rated current In of 50 A and a frame rating Iu of 160 A. The TMA trip unit offers adjustable overload protection from 50 to 500 A, making it suitable for a range of feeder and branch circuit applications in low-voltage switchboards.

Trip unit and adjustability

The thermal-magnetic trip unit (TMA) covers a wide continuous current adjustment band — set at 50 A as shipped, but can be dialed up to 500 A without changing the breaker. Fixed front terminals (F F) match standard panel bus connections and simplify replacement wiring.
