Frequently Asked Questions

What does the TMF designation mean in A1N 125 TMF 63-630 4p F F?
TMF refers to the thermal-magnetic trip unit type, providing both overload (thermal) and short-circuit (magnetic) protection in a single integrated unit.

Is the ABB 1SDA068775R1 suitable for use on both AC and DC systems?
The verified breaking capacity specification references 240 V AC. Please consult the official ABB Formula A1 product datasheet for full voltage ratings and DC applicability.

What does the '4p F F' suffix indicate?
4p denotes a 4-pole configuration. The 'F F' designation indicates a fixed (non-withdrawable) mount on both the breaker and the base/frame side.
