  • Product description

    Schneider Electric INS320 Modular 3P 320 A Switch Disconnector

    The Schneider Electric INS320 is a manually operated 3-pole switch disconnector designed for switching and isolating an electrical circuit. The device is operated using a long black rotary handle, has clearly indicated 0–1 positions and is intended for fixed installation in an electrical distribution or control panel.

    The switch disconnector has a rated uninterrupted current of 320 A, a maximum operational voltage of 690 V AC and a specified operational power of 160 kW. Its three-pole construction allows three conductors of a three-phase circuit to be switched or disconnected simultaneously with a single turn of the handle.

    The device is suitable for industrial and commercial electrical panels, equipment supply circuits, automation systems and other electrical distribution applications requiring reliable manual circuit isolation.

    Important information

    • The switch disconnector is not a circuit breaker.
    • It does not protect the circuit against overloads or short circuits.
    • A correctly selected separate protective device must be installed in the circuit.
    • The IP40 rating applies to the front of the installed device.
    • The device must be installed in a suitable electrical enclosure.

    Installation and operation

    1. Check the system voltage, current, load power and short-circuit parameters.
    2. Select conductors with a suitable cross-section and compatible connection terminals.
    3. Install the switch disconnector in an electrical panel using the method specified by the manufacturer.
    4. Connect the conductors to the screw terminals and tighten them to the specified torque.
    5. Provide separate protection against overloads and short circuits.
    6. After installation, check the operation of the 0–1 positions.
    7. Installation and maintenance work must only be carried out after disconnecting the power supply.

    Quick selection guide

    Choose this 3P 320 A switch disconnector when a three-phase electrical circuit requires a manually operated device for switching and isolation. Before ordering, check the system voltage, rated current, load power, number of poles, mounting method and the required overload and short-circuit protection.

    Important safety warning:
    The switch disconnector must be installed, connected and serviced by a qualified professional. Before starting work, disconnect the power supply, verify the absence of voltage and follow all applicable electrical safety requirements.

    Frequently asked questions

    Is the INS320 a circuit breaker?

    No. It is a manually operated switch disconnector. It does not provide overload or short-circuit protection.

    What do the 0–1 positions mean?

    Position 0 indicates that the circuit is switched off or isolated, while position 1 indicates that the circuit is switched on.

    Is this switch disconnector suitable for a three-phase system?

    Yes. Its three-pole construction allows three conductors of a three-phase circuit to be operated simultaneously.

    Does the switch disconnector provide short-circuit protection?

    No. A separate circuit breaker, fuse system or another correctly selected protective device must be installed.

    What does the IP40 protection rating mean?

    IP40 provides protection against solid objects larger than 1 mm but does not provide protection against water. This rating applies to the front of the correctly installed device.

    Who may install this switch disconnector?

    Installation and connection must be performed by a qualified professional in accordance with the manufacturer’s documentation and applicable electrical safety requirements.
