Network aggregation modular switch, 4-way, 40 A PSA-440

Modular network-generator switch – reliable power switching

This 4-pole network-generator installation switch is a key element in backup or alternative power systems. It allows switching between two power sources (e.g., mains and generator) or completely disconnecting the circuit. The modular design makes it easy to integrate with existing electrical installations, and its solid construction guarantees long-lasting and trouble-free operation.

Functionality and application

The PSA-440 switch implements a 1-0-2 switching program, which means it allows connecting one of two input lines to the output or completely disconnecting the circuits. This is an ideal solution in situations where power reliability and the ability to quickly switch to an alternative energy source are required. It finds application in:

• Residential and commercial buildings with emergency power systems.
• Workshops and production plants where power outages can cause serious losses.
• Installations requiring flexible power source management.
• Life support systems where continuous power supply is critical.

Characteristics and benefits

The PSA-440 switch has been designed with ease of installation and use in mind. Made of high-quality plastic, it provides good electrical and mechanical insulation. Screw terminals allow for secure and durable connection of wires with a cross-section of up to 16 mm². Thanks to its compact dimensions (4 modules – 70 mm wide), it takes up little space on the TH-35 rail.

• High reliability: Electrical endurance at 5000 cycles and mechanical endurance at 15000 cycles guarantee a long service life.
• Safety: IP20 protection degree protects against accidental contact and the ingress of solid objects larger than 12.5 mm.
• Easy installation: Designed for mounting on a standard TH-35 rail, which facilitates and speeds up installation.
• Versatility: The ability to connect wires with a cross-section of up to 16 mm² ensures compatibility with various types of electrical installations.
• 1-0-2 switching program: Provides flexibility in managing power sources and the ability to completely disconnect the circuit if necessary.
• Resistance to environmental conditions: Designed to operate at temperatures from -20°C to +50°C, allowing it to be used in various environmental conditions.

The PSA-440 switch is a solid and functional solution for anyone who needs a reliable network-generator switch for their electrical installation. Its versatility and ease of installation make it an ideal choice for both professional installers and end-users who care about the safety and continuity of power to their devices.
