3-pole +N isolating switch (disconnected) 125 A for external knob RSI-4125N\W01

Insulating disconnect switch – safety and reliability in your installation

This insulating disconnect switch, with a rated current of 125 A, 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 reliable operation. Its design allows for complete isolation of the circuit, which is particularly important during maintenance and service work.

Construction and application

The RSI-4125N\W01 disconnect switch is a permanently mounted device designed for mounting on a plate. It has 4 poles (3P+N) with the possibility of disconnecting the neutral (N), which increases its application flexibility. Equipped with an external control knob, it enables easy and intuitive operation. As an emergency switch, it provides quick disconnection of power in crisis situations. It will be useful in electrical switchboards, control cabinets and anywhere where reliable circuit isolation is required.

Key features and benefits

• High resistance to environmental conditions: meets IEC standards for vibration, shock and cyclic damp heat, guaranteeing long-lasting and trouble-free operation even in difficult conditions.
• Wide voltage range: adapted to operate at a maximum voltage of 690 V AC, making it a universal solution for various installations.
• High durability: withstands thousands of mechanical (8000) and switching (1000) cycles, ensuring long-term operation.
• Safety of use: has an IP20 degree of protection, protecting against accidental contact and protecting against the influence of solid bodies larger than 12.5 mm.
• Installation flexibility: plate mounting allows easy integration with existing distribution systems.
• Suitable for conductors with large cross-section: allows connection of conductors with a cross-section from 25 to 70 mm², allowing use in installations with high load.
• Rated operating power for AC-23, 400 V is 30 kW, which proves its efficiency in industrial applications.
• Rated short-circuit current Icm is 7.5 kA, which provides effective protection against the effects of short circuits.

Technical parameters in practice

This disconnect switch is characterized by high technical parameters confirming its reliability and safety: the rated continuous current Iu is as much as 125 A, and the rated short-time withstand current Icw(1s) is 2.5 kA. This makes the device perfectly cope with loads occurring in typical electrical installations. The use of screw connections ensures a secure and durable connection of the conductors. In addition, high resistance to shock and vibration guarantees stable operation even in demanding industrial conditions.
