It combines a thermal-magnetic overload relay and a magnetic short-circuit trip in a single enclosure, sized for direct motor starting without a separate contactor for manual on/off control. Rated at 16 A, this unit provides overload protection for motors drawing up to that full-load current, with the trip threshold set via the front dial to match the motor nameplate. ## Lifecycle status and replacement path The MS450-16 is listed as current production but has been replaced by the MS132-16 manual motor protector. This means the MS132-16 is the recommended go-forward order code for new designs and replacement stock, though the MS450-16 remains available through independent distribution for existing BOM positions that require the exact original part number. For a panel already wired for the MS450-16, the MS132-16 shares the same functional class — 3-phase manual motor protection — but the mounting footprint and terminal layout should be verified against the panel cutout and wiring plan before substituting. The MS132-16 covers the same adjustable current range of 11-16 A. ## Sourcing this part for your BOM For production quantities or urgent line-down needs, the MS132-16 replacement should be evaluated as the primary sourcing path.","metaTitle":"ABB MS450-16 Manual Motor Protector, 16 A, 3-Phase","metaDescription":"ABB MS450-16 3-phase manual motor protector, 11-16 A range, 50 kA breaking capacity.
