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.

Frequently asked questions

What is the frame size Iu?

The frame rating Iu is 160 A, which defines the maximum continuous current the breaker can carry at its reference temperature.

What trip unit does this breaker use?

It uses a TMA thermal-magnetic trip unit with an adjustable overload range from 50 to 500 A.
