3-pole +N isolating switch (non-disconnectable) 125 A in ABS housing with black/green handle On/Off RSI-3125N\OBAZC

Insulation disconnect switch – safety and reliability in your installation

This disconnect 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 installers and end-users, it offers a solid construction and easy installation. Made of high-quality materials, it guarantees long-lasting and trouble-free operation.

Construction and application

The RSI-3125N\OBAZC disconnect switch is a device designed for safely disconnecting electrical circuits. It has 3 poles and a neutral (N) pole which is non-disconnectable – meaning the neutral is always disconnected together with the phases. The housing made of ABS provides mechanical strength and resistance to environmental conditions. The yellow-red (Y/R) knob allows for intuitive operation and quick identification of the device status. It is an ideal solution for use in residential, commercial and industrial buildings.

Advantages and benefits

• High short-circuit resistance: Rated conditional short-circuit current of 7.5 kA provides effective protection of the installation in the event of a failure.
• Universal mounting: The possibility of mounting on a plate makes it easy to integrate the disconnect switch into various types of switchboards.
• Safety of use: As an emergency switch, it allows for quick and safe disconnection of power in emergency situations.
• Durability and reliability: Made of high-quality materials guarantees a long service life of the device and minimizes the risk of failure. Tested for resistance to vibration, impact and cyclic damp heat (according to IEC standards).
• Wide voltage range: Designed to operate at a maximum voltage of 690V AC, making it compatible with various power systems.
• Easy connection of wires: Screw connection ensures a secure and durable connection of wires with a cross-section from 25 to 70 mm².
• Rated operating power for AC-23, 400 V: 30 kW – allows use in circuits powering motors and other high-power devices.

Technical parameters and compliance with standards

The disconnect switch meets safety requirements, which confirms its high quality and reliability. It has a degree of protection of IP20 on the front side, which protects against accidental contact. The rated continuous current is 125A, and the rated short-time withstand current is 2.5 kA. The device has a mechanism blocking the knob position, which prevents accidental switching on or off of the circuit during operation. It is a fixed-mounted device – it does not have a motor drive or an optional voltage release.
