Schneider Compact INS/INV Switch Disconnectors

The Schneider Electric ComPacT INS/INV Switch Disconnectors are designed for manual switching, circuit isolation and load disconnection in low-voltage electrical distribution systems. Covering rated current options from 40 A to 2,500 A, the series offers 3-pole and 4-pole configurations for a wide range of industrial and commercial applications. Featuring reliable rotary operating mechanisms, clear disconnection indication and compatibility with Schneider Electric circuit breakers and accessories, the ComPacT INS/INV series provides flexible isolation solutions for power distribution panels, switchboards and industrial electrical installations.

Reliable Switching and Electrical Isolation

The ComPacT INS/INV series is designed for switching and isolating electrical circuits under specified operating conditions. It supports multiple utilization categories, including AC-22A and AC-23A for different AC load types, as well as DC-22A and DC-23A for applicable DC switching applications. Its rotary operating mechanism provides convenient manual control, while the isolation function supports safe electrical disconnection during inspection and maintenance.

INS and INV Disconnection Indication

The series includes two main product types with different disconnection indication designs:

• ComPacT INS: Features positive break indication, providing a mechanically linked indication of the open contact position for isolation verification.

• ComPacT INV: Features visible break indication, allowing operators to visually confirm the contact separation through the designated viewing arrangement.

Both versions are designed to meet applicable isolation requirements under IEC/EN 60947-3, supporting safe switching operations in low-voltage distribution systems.

Flexible Installation and Accessory Compatibility

The ComPacT INS/INV series offers multiple frame sizes and installation configurations to accommodate different switchboard designs. Available 3-pole and 4-pole versions support different electrical distribution arrangements. Compatible accessories include direct and extended rotary handles, auxiliary contacts, terminal connections, interlocking kits and padlocking devices. Selected configurations also support PowerTag energy sensors and current measurement accessories for enhanced electrical monitoring.

The series can be coordinated with Schneider Electric Masterpact MTZ, NT and NW, ComPacT NS, NSX and Acti9 circuit breakers to support integrated switchboard designs.

Applications

The ComPacT INS/INV Switch Disconnectors are suitable for manual circuit isolation and switching in industrial and commercial low-voltage electrical distribution systems. Typical applications include:
