Product questions
What current range and motor rating does the ABB MS132-25 cover?
The overload setting range is 20–25 A, and its rated operational current is 25 A. Its AC-3 and AC-3e rating is 11 kW for a three-phase motor at 400 V. Check the motor nameplate current, supply, starting conditions and protection coordination before selection.
What is the short-circuit breaking capacity of 1SAM350000R1014?
The rated service short-circuit breaking capacity Ics is 50 kA at 400 V AC and 50 kA at 230 V AC. The rating depends on voltage and configuration; verify the prospective fault current and protection coordination for the installation.
Can the MS132-25 be used with a single-phase motor?
ABB describes the MS132-25 as suitable for single- and three-phase applications. Suitability for a particular motor depends on its current, voltage and the applicable connection arrangement; have a qualified person verify the application and manufacturer instructions.
What protection and switching functions does the MS132-25 provide?
It provides overload and short-circuit protection, phase-loss sensitivity, manual switching and a disconnect function. It has a trip-free mechanism and a lockable rotary handle. Phase-loss sensitivity should not be treated as a guarantee of protection in every operating condition; a qualified person should assess the motor protection scheme.
How is the MS132-25 mounted and connected?
It has screw terminals and can be mounted on a TH35-7.5 or TH35-15 DIN rail. The housing is IP20 and the main circuit terminals are IP10. Check enclosure and wiring requirements for the installation.
