Frequently Asked Questions

Q: What does the TMD trip unit mean on the XT1S 160 TMD 160-1600 3p F F?
A: TMD stands for Thermal-Magnetic with adjustable overload (Ir) and fixed short-circuit (Im) settings. The range 160–1600 denotes the adjustable overload current setting band.

Q: What is the mounting style of this breaker?
A: The designation "F F" indicates fixed mounting — both the breaker itself and its connection terminals are fixed, meaning it is bolted directly into the switchboard or panel.

Q: Is the ABB 1SDA067436R1 suitable for use in explosive atmospheres?
A: Yes, the XT1S 160 TMD 160-1600 3p F F carries ATEX certification, making it suitable for installation in potentially explosive environments in accordance with EU Directive 2014/34/EU.
