ABB 1SDA068057R1 XT3N 250 TMD 160-1600 3p F F molded case circuit breaker

ABB 1SDA068057R1 is a low-voltage molded case circuit breaker from the Tmax family. The complete ABB part number is 1SDA068057R1. It is specified for dependable switching and protection against overload and short circuit in distribution panels, control panels, motor feeders, HVAC systems, pump control panels, commercial buildings and industrial installations.

This ABB XT3N 250 TMD 160-1600 3p F F configuration combines a 3-pole circuit breaker, a frame rating of 250 A, a current setting of 160-1600 A and a rated short-circuit breaking capacity of 36 kA at 415 V AC. The breaker is fixed and uses a fixed TMD trip arrangement where specified.

The ABB Formula and Tmax families are designed for clear selection by frame size, pole configuration, current setting and Icu/Ics performance. For procurement, replacement and panel-bill-of-materials work, use the exact reference 1SDA068057R1 and the model identifier XT3N 250 TMD 160-1600 3p F F to avoid mixing breaker frames, trip units or interrupting capacities.
