3-pole +N isolator switch (disconnected) 125 A in polycarbonate housing RSI-4125N\OBP

Isolator switch – reliable power disconnection

This isolator switch, with a rated current of 125A, is a robust solution for safely disconnecting electrical circuits. Designed for both professional and home use, it provides effective protection for installations and devices. Made of high-quality polycarbonate, it is characterized by durability and resistance to mechanical damage. The RSI-4125N\OBP model with a disconnected N is particularly useful in installations requiring complete isolation.

Design and application

This isolator switch finds application in a wide range of electrical installations – from residential and commercial buildings to industrial facilities. Its main task is to ensure safe disconnection of the circuit during maintenance, repair or emergency work. The design with four poles (3P+N) allows disconnection of both phases and neutral, which increases the level of safety. The locking mechanism prevents accidental opening of the switch under load.

Key features and benefits

• High resistance to external conditions: The polycarbonate housing (IP20) provides protection against touch and limited protection against the ingress of solid objects.
• High short-circuit breaking capacity: Short-circuit current withstand of 7.5 kA guarantees effective protection of the installation in the event of a short circuit.
• Universal mounting: Plate mounting allows for easy integration with existing distribution boards.
• Safety of use: As an emergency switch, it allows for quick and safe disconnection of power in hazardous situations.
• Durability and reliability: Mechanical endurance of 8000 cycles and switching endurance of 1000 cycles ensure long-lasting and trouble-free operation of the device.
• Wide voltage range: The ability to operate at a maximum voltage of 690V AC makes it a universal solution for various installations.
• Suitable for large cross-section cables: Support for cables with a cross-section of 25-70 mm² allows connection of even thick power cables.
• Rated operating power for AC-23, 400 V is 30 kW, which makes it suitable for more demanding applications.

The RSI-4125N\OBP isolator switch is an investment in the safety and reliability of your electrical installation – for both professionals and home users.
