54 A manual motor starter — what it handles
The ABB MS165-54 is a 3-pole manual motor starter rated 54 A at 600 VAC, with screw terminals and a rotary handle for manual on/off and overload reset. The 54 A continuous rating means it directly protects a motor drawing up to that full-load current — the thermal-magnetic trip element tracks motor heating, not just fault current.
How it compares to the MS116 family
The MS165-54 is a larger-frame starter than the MS116 series. The MS116-1.0 is rated 10 A and the MS116-6.3 is rated 6.3 A — both are 3-pole manual motor protectors but in a smaller physical package.
