The 20 A maximum sets the thermal-magnetic trip threshold for overload and short-circuit protection on a 3-phase motor branch. ## Mounting and panel integration Surface-mount form factor — the protector mounts directly to a panel backplate or enclosure wall, not on a DIN rail. This suits retrofit or legacy panel layouts where the existing cutout or mounting pattern expects a surface-mount device.","metaTitle":"ABB MS325-20 Manual Motor Protector, 20 A, 3-Phase","metaDescription":"ABB MS325-20 manual motor protector, 16-20 A, 3-phase, surface mount.
