ABB MSSP1-T2P Manual Motor Controller Enclosure

ABB MSSP1-T2P Manual Motor Controller Enclosure Type 1 is a two-pole manual motor starter housed in a Type 1 general‑purpose enclosure from ABB’s MSSP family. It is designed for panel installations requiring a visible, accessible on/off control of small motors, with the T2P designation indicating two-pole toggle operation. Electrical ratings for this variant include 115–230 V AC operation up to 1 HP, and 277 V AC operation up to 1 HP; for DC operation, it supports 115–230 V DC up to 3/4 HP. This enclosure provides a protective housing for the two‑pole controller assembly within a Type 1 environment, safeguarding the switch and wiring from typical shop‑floor dust and incidental contact inside a control panel. The MSSP1 family covers multiple mounting and configuration options, for example MSSP1-T2PS offers a flush‑mount version with the same two‑pole switch. Common applications include basic motor control in conveyors, fans, pumps, and machine tools where a simple local start/stop control is required in a panel or control box. When selecting a variant, verify the mounting style (surface vs flush) and ensure voltage and horsepower ratings align with the motor being controlled.
