Power source transfer switch 63A, 4-pole, with silver-black front, PRZK-4063\WO2 PRZK-4063\W02

Power source switch – reliable power switching

The PRZK-4063\W02 power source switch is a robust solution for switching between different power sources, such as the mains and a generator. The design based on RSI disconnectors guarantees high reliability and safety of use. The device is particularly useful in emergency situations, ensuring the continuity of power supply to critical circuits.

Construction and application

The PRZK switch is a combination of two RSI disconnectors connected by a common housing. This construction provides rigidity and stability, which translates into reliable operation in various conditions. This switch finds application in both home and industrial installations where reliable switching of power sources is required. It is ideal for uninterruptible power supply (UPS) systems and in places where there is a risk of power outages.

Key features and benefits

• Durable construction: Made of plastic, providing good insulation and resistance to mechanical damage.
• High reliability: Based on proven RSI disconnectors, guaranteeing long-lasting and trouble-free operation.
• Safety of use: Provides effective protection against overload and short circuit, protecting the electrical installation and connected devices.
• Easy installation: Designed for mounting on a TH35 rail, which facilitates installation and integration with existing electrical infrastructure.
• Wide range of applications: Ideal for switching between the mains and a generator in homes, businesses and industrial facilities.
• High rated value: Rated current of 63A allows handling loads with significant power.
• Resistance to external conditions: Withstands vibrations, shocks and humid environments in accordance with IEC 60068-2-6, IEC 60068-2-27 and IEC 60068-2-30 standards.
