    AC switch-disconnectors for safe switching and isolation

    AC switch-disconnectors are used wherever electrical circuits need to be switched, isolated or safely disconnected for maintenance work. At plica, you will find robust AC switch-disconnectors for general applications, machines, systems, distribution boards, industrial environments and emergency stop applications.

    The range includes compact versions from 16 to 160 A, 3P+N variants, high-performance switch-disconnectors up to 1600 A and versions for emergency use. Depending on the series, the switches offer high protection ratings, robust enclosures, large wiring spaces, clear position indicators and lockable rotary handles for safe operation.

    The following chapter overview helps you quickly find the right AC switch-disconnector for your application.

    Function and applications

    Safe switching, isolation and maintenance

    AC switch-disconnectors are used for the safe switching and isolation of electrical circuits. Depending on the version, they are suitable as main switches, maintenance switches or safety switches in distribution boards, machines, systems and industrial installations.

    Current ranges and variants

    From compact systems to high power applications

    AC switch-disconnectors are available in different current ranges depending on the application. Compact versions from 16 to 160 A are suitable for many standard installations. For higher power requirements, versions up to 1600 A are available. 3P+N variants are also available when the neutral conductor must be included in addition to the phases.

    • AC switch-disconnectors 16 to 160 A
    • AC switch-disconnectors 160 to 250 A
    • AC switch-disconnectors 100 to 1600 A
    • 3P+N variants
    Protection rating, enclosure and operation

    Robust solutions for demanding environments

    In demanding environments, the protection rating, enclosure design and ease of operation are crucial. Many AC switch-disconnectors feature high protection ratings such as IP66/IP69 or IP65 as well as high impact resistance. Lockable rotary handles, clear position indicators and large wiring spaces support safe, tidy and service-friendly installation.

    Emergency stop applications

    Switch-disconnectors for higher operational safety

    For safety-relevant applications, AC switch-disconnectors are also available in versions for emergency use. They support reliable shutdown of machines and systems and help implement professional maintenance and safety concepts.

    AC or DC switch-disconnector

    Select according to current type and application

    AC switch-disconnectors are used for alternating current applications. For direct current applications, for example in photovoltaic systems between the solar module and the inverter, DC switch-disconnectors are the right choice. Key selection criteria include current type, rated current, number of poles, protection rating, enclosure, installation situation and required lockability.

    Selection and advice

    Determine the right switch-disconnector

    When selecting an AC switch-disconnector, rated current, number of poles, installation location, protection rating, operating concept and safety requirements should be considered. Our specialists will be pleased to help you choose the right version for your system, machine or electrical installation.
