Product questions
What does the ABB SK1-11 signaling contact do?
The SK1-11 signals a manual motor starter trip, including trips caused by overload, short circuit or an electrical release. It is a trip-signaling contact rather than a general indication of the starter’s normal on/off position.
Which contacts and terminals does 1SAM201903R1001 have?
It has one normally open and one normally closed auxiliary contact, with screw terminals. It mounts on the right side of the motor starter.
Will the SK1-11 fit my ABB manual motor starter?
The published suitable series include MS116, MS132, MO132, MS165 and MO165. Confirm the exact starter model, serial number and accessory arrangement before ordering; a series name alone does not establish every installation combination.
What voltage and current ratings should be checked for the SK1-11?
The listed operational voltage is 690 V AC or 600 V DC. Current depends on voltage and utilization category: for example, AC-15 is 4 A at 240 V, while DC-13 is 0.55 A at 125 V. Check the complete rating for the intended control circuit.
Does the SK1-11 automatically reset after a trip?
The signaling contact has an orange trip indicator, and its contact positions require manual reset after a trip. Consult the applicable ABB instructions for the equipment before operating it.
