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.","metaTitle":"ABB 1SDA068084R1 XT4N 160 TMA Distribution Circuit Breaker,","metaDescription":"Active production ABB XT4N 160 TMA 3-pole distribution breaker.
