Schneider Electric 31330 ComPacT INS800 800A 3P Switch Disconnector – Black Rotary Handle

Description

The Schneider Electric 31330 ComPacT INS800 is an 800A 3-pole switch disconnector designed for high-current electrical distribution, circuit isolation and switching applications. It is a non-automatic switch-disconnector with a standard black rotary handle, providing reliable manual operation for low-voltage power distribution systems. Schneider Electric lists reference 31330 as an INS800 3P 800A switch disconnector.

The ComPacT INS800 800A switch disconnector is rated for operation on 50/60Hz AC networks and supports rated operational voltages up to 690V AC. At 380/415V AC, the device is rated at 800A for utilization categories including AC-21A, AC-22A and AC-23A, making it suitable for switching and isolation duties in demanding electrical distribution systems.

Unlike an MCCB, the INS800 is a switch disconnector rather than an automatic circuit breaker. Its primary functions are switching, isolation and safe disconnection of electrical circuits. The device provides positive contact indication, helping users verify the physical contact position during isolation procedures. Schneider Electric specifies its isolation suitability according to the applicable IEC requirements.

The 31330 INS800 3P switch disconnector uses a black rotary handle designed for straightforward manual operation. Its configuration is intended for installation in electrical switchboards, distribution panels and other low-voltage power-distribution equipment where high-current circuit switching and isolation are required.

For DC applications, Schneider Electric specifies the INS800’s DC utilization ratings with two poles in series, including DC-21A, DC-22A and DC-23A operation at 125V DC. The actual installation must follow Schneider Electric’s specified pole configuration and application requirements.

The Schneider Electric 31330 belongs to the ComPacT INS/INV family and is available with compatible accessories and auxiliary functions depending on the selected configuration. Schneider Electric also highlights the current ComPacT platform’s ergonomic operating design and installation improvements for panel builders.

With its 800A current rating, 3-pole configuration, 690V AC rating and rotary-handle operation, the ComPacT INS800 31330 is well suited to high-current distribution and isolation applications where dependable manual switching is required.
