ABB MS325 Manual Motor Starter

ABB MS325 Manual Motor Starter is a compact, 3‑pole device designed to start and protect small three‑phase motors up to 690 V AC, with a current range of 4–6.3 A and a maximum motor power of 5 HP. It is designed for DIN rail mounting on TH35‑15 rails and occupies a 54 mm width in standard configurations, making it straightforward to integrate into compact control panels. An auxiliary contact is included to provide signaling or interlocking in the control circuit, enhancing integration with interlocks and indicators. The MS325 family includes variants such as MS325‑6.3, which specifically supports 4–6.3 A at 690 V and is widely documented in ABB datasheets and distributor catalogs for 3P operation.
