Rotary modular switch network - generator 80A PSR-480

Rotary mains-generator switch – a reliable power source

This 4-pole, modular mains-generator switch PSR-480 is a robust solution for switching between two power sources or completely disconnecting the circuit. Designed for both industrial and commercial applications, it provides safe and efficient energy management. Its design allows for flexible mounting on a DIN rail or mounting plate, making it easy to integrate with existing infrastructure.

Functionality and application

The PSR-480 switch implements a 1-0-2 switching program, allowing you to select one of two power sources or completely cut off the load. This functionality is particularly useful in backup systems where ensuring continuous power supply is critical. It can be used in electrical switchboards, industrial automation systems and anywhere reliable circuit switching is required. Thanks to its high mechanical (10,000 cycles) and electrical strength, it guarantees long-lasting and trouble-free operation.

Key features and benefits

• High current capacity: Rated continuous current of 80A allows for servicing demanding loads.
• Universal mounting: The possibility of mounting on a DIN rail or mounting plate provides installation flexibility.
• Safety: Insulation voltage Ui 800V and impulse voltage Uimp 8kV provide protection against overvoltage and short circuits.
• Durable construction: Made of high-quality plastic, resistant to mechanical damage and environmental conditions.
• 1-0-2 switching program: Allows you to select one of two power sources or completely disconnect the circuit – an ideal solution for backup systems.
• Wide operating temperature range: From -20°C to 50°C – possibility of use in various environmental conditions.
• Screw terminals: Allow connection of wires with a cross-section from 2.5 mm² to 35 mm², ensuring a secure electrical connection.
• Compact dimensions: Width of 8 modules (135 mm) allows for efficient use of space in the switchboard.
• Protection class IP20: Protects against accidental contact with live parts.

This switch is not only an element of electrical installation – it is an investment in the safety and reliability of the power system. Its solid construction and functionality make it the ideal choice for both professional installers and end-users looking for a proven energy management solution.
