Main switch (isolator), 32A, 3-pole HIS-32/3 167352

HIS-32/3 Disconnector with Padlock Lockability

The HIS-32/3 main isolation disconnector is a reliable component for power systems, designed for the safe disconnection of three-phase circuits with a rated current of 32A. The device operates at a voltage of 415V AC, making it an ideal solution for domestic, commercial, and light-industrial switchboards.

Design and Technical Parameters

The compact design occupies 3 modules in a standard switchboard, with a mounting depth of 69.5 mm, enabling installation in typical electrical enclosures. Compliance with the IEC/EN 60947-3 standard guarantees the highest standards of safety and reliability.

The device features a high switching capacity of 12.5 kA and a short-circuit withstand strength of 1 kA, ensuring effective protection against the effects of emergency operating states in the installation. The IP40 protection rating is suitable for equipment mounted inside switchboards.

Functionality and Operational Safety

The disconnector is equipped with screw terminals suitable for conductors with a cross-section of up to 50 mm², allowing for the connection of even thick power cables. The design allows for a continuous current of up to 125A, providing a large safety margin during normal operation.

A special feature is the ability to lock the lever with a padlock, which prevents accidental switching during service or maintenance work. The arrow symbol on the handle clearly indicates the power disconnection function.

Application and Compatibility

The device is effective as a main or sectional disconnector in three-phase installations, providing a comprehensive disconnection of all three phases simultaneously. Mounting on a standard TH35 rail allows for quick installation in existing distribution systems.

An operating temperature from -5°C to +40°C allows for use both indoors and in technical rooms with variable environmental conditions. CE compliance ensures legality of use within the European Union.
