Schneider Electric MSA-9A-220V-2.5-4A Manual Motor Starter

The Schneider Electric MSA-9A-220V-2.5-4A Manual Motor Starter is an electromechanical motor control assembly that pairs a 9 A, 3-pole contactor with a 220 VAC coil and an adjustable overload relay set for 2.5–4 A to provide manual motor starting and thermal protection for three‑phase industrial motors. Built for use in industrial motor control panels and OEM automation systems, it supports panel mounting or DIN rail mounting and uses an open-type enclosure (assembly dependent), and it is part of Schneider's TeSys series (assembly dependent). Typical applications include conveyors, pumps, compressors, packaging equipment, water treatment facilities, HVAC equipment, and material handling systems where operator-controlled starting and reliable overload protection are required. Key specifications include: Contactor current rating 9 A, coil voltage 220 VAC, overload relay setting range 2.5–4 A, number of poles 3, control type manual and electromechanical, operating frequency 50/60 Hz, mounting type panel or DIN rail, and enclosure open type (assembly dependent); it is designed to work with Schneider motor circuit breakers for short-circuit protection. Common replacements include the Schneider GV2ME10 Manual Motor Starter and the LC1D09 Contactor with LRD10 Overload Relay.
