3-pole +N isolator switch (non-disconnectable) 125 A in ABS housing RSI-3125N\OBA

Isolator switch – safety and reliability in your installation

This isolator switch, with a rated current of 125A, is a key element ensuring the safe and efficient operation of the electrical installation. Designed for both professional and demanding users, it offers a solid construction and high performance parameters. Made of high-quality materials, including an ABS housing, it guarantees durability and resistance to external factors.

Construction and application

The RSI-3125N\OBA isolator switch is a device designed for safely disconnecting electrical circuits. Its construction allows for mounting on a plate, which facilitates integration with existing systems. As an emergency switch and main isolator, it provides effective protection against overloads and short circuits. The mechanism with a knob allows for intuitive operation, and the inability to disconnect the neutral (N) in the non-disconnecting version ensures continuous power supply for sensitive receivers. The rated current of 125A allows for servicing a wide range of devices with higher power consumption.

Key features and benefits

• High resistance to environmental conditions: The ABS housing provides protection against mechanical damage and the effects of atmospheric factors.
• Safety of use: As an emergency switch and main isolator, it effectively protects the installation from dangerous situations.
• Universal mounting: The possibility of mounting on a plate facilitates integration with various distribution systems.
• High durability: Mechanical durability of 8000 cycles and switching durability of 1000 cycles guarantees long-lasting and reliable operation of the device.
• Wide range of applications: Rated current of 125A enables use in circuits with high power demand, e.g. in workshops, production halls or commercial buildings.
• Compliance with standards: The device meets the required safety standards, which confirms its high quality and reliability.
• Adapted to work in difficult conditions: Withstands vibrations, shocks and humid environments (IP20 protection class on the front side).

Technical parameters in practice

Rated continuous current of 125A means that the isolator is adapted for long-term operation under such load without the risk of overheating or damage. Rated conditional short-circuit current of 7.5 kA indicates its ability to withstand short-term overvoltages without damage. Rated operating power for AC-23, 400 V of 30 kW allows you to connect devices with significant power - electric motors or industrial heaters - without fear of overloading the isolator. The cross-section of connection cables from 25 to 70 mm² provides flexibility when choosing cables adapted to a specific application.
