The Iron Sheet Metal Main Switch (Triple Pole) is a robust and reliable power control device designed for safe disconnection and isolation of three-phase electrical circuits. Housed in a durable iron sheet metal enclosure, it offers superior mechanical strength, corrosion resistance, and long service life in both indoor and outdoor industrial environments. This triple pole main switch ensures simultaneous breaking of all three phases, minimizing electrical hazards during maintenance or emergencies. Fitted with high-quality contacts, strong terminals, and easy-to-operate handles, it is ideal for use in factories, workshops, commercial buildings, and heavy electrical installations.

Changeover Switch Fuse Units are typically available in current ratings from 32A to 800A and voltage ratings up to 415V AC, suitable for both three-phase and single-phase systems. The unit consists of a robust switch-disconnector mechanism combined with high rupturing capacity (HRC) fuse links for reliable overload and short-circuit protection. The switch allows manual transfer between two power sources with clear ON–OFF–CHANGEOVER positions and positive break operation. Enclosures are fabricated from CRCA steel sheets with a powder-coated finish or thermoplastic housing, providing IP42 to IP54 protection levels. Fuse chambers are front-accessible for easy maintenance and fuse replacement. The terminals are copper or tinned brass for high conductivity, and internal components are designed for arc quenching and long mechanical life. These units comply with IS/IEC 60947-3 and are ideal for use in feeder panels, generator rooms, and power distribution networks requiring both control and protection functionalities.
