3-pole +N 80A power source switch in enclosure, ABS enclosure with black knob PRZK-3080NOBA/ PRZK-3080NOBA\/

Power source switch – reliable switching between mains and generator

This 3-pole switch with a built-in neutral terminal (N) and a current of 80A, in a solid ABS housing with a black knob, is a key element of emergency power systems. It is used to safely and manually switch between two power sources – the power grid and a generator – or to completely disconnect the circuit. It is an ideal solution for both installers and end-users who value reliability and safety.

Functionality and application

The PRZK-3080NOBA switch allows for a quick response to voltage drops in the grid, automatically switching the power to an alternative source (generator). The 3P+N construction provides full protection of the installation, and the presence of a neutral terminal guarantees the correct operation of devices sensitive to interference. It will be useful in single-family homes, workshops, small production plants and everywhere where uninterrupted power supply is critical. The ability to completely disconnect the circuit (position "0") increases safety during maintenance and service work.

Key features and benefits

• High current capacity: Rated current of 80A allows operation of demanding three-phase installations without risk of overload.
• Durable construction: The housing made of durable ABS provides resistance to mechanical damage and weather conditions.
• Intuitive operation: Clear markings and a solid knob make it easy to switch between power sources.
• Safety: The presence of a neutral terminal (N) and the "0" position ensure full protection of the installation and devices.
• Mounting: Designed for mounting on a TH35 rail, which facilitates integration with existing switchboards.
• Versatility: Suitable for use in residential, commercial and industrial buildings.
• Non-detachable N terminal: Provides a stable connection of the neutral in TN-C system or with a fixed N connection in the switchboard.

Technical parameters in practice

The switch is characterized by high resistance to environmental conditions – it withstands vibrations and shocks in accordance with IEC 60068-2-6 and IEC 60068-2-27 standards. The rated short-circuit current is 10kA (using a gG 63A fuse), which provides effective protection against the effects of short circuits. Mechanical durability at 10,000 cycles guarantees long-term and trouble-free operation of the device. The cross-section of the connection wires is 10...25 mm², which allows connection of wires of appropriate thickness to ensure optimal performance.
