Product questions
What is the current setting range of ABB 1SAM451000R1016?
The ABB MS165-54 has an adjustable overload setting range of 40–54 A and a rated operational current of 54 A. Check that the motor's rated current falls within the setting range and verify the complete application before selecting it.
What protection and operating features does the MS165-54 provide?
It provides motor overload and phase-failure protection, with trip class 10, and short-circuit protection. It also has a disconnect function, lockable rotary handle and fault indication. Confirm suitability for the installation and available fault current before use.
What are the motor power and short-circuit ratings at 400 V?
For three-phase AC-3 operation at 400 V, the MS165-54 is rated 22 kW. Its 400 V AC service breaking capacity Ics is 30 kA and ultimate breaking capacity Icu is 50 kA. Breaking capacity depends on voltage and must be checked against the installation's prospective fault current.
What are the MS165-54 dimensions and terminal type?
The listed dimensions are 55 mm wide, 142.65 mm high and 122.1 mm deep; the unit uses screw terminals. It can be mounted on a suitable DIN rail. Check enclosure clearance and wiring requirements for the installation.
