Isolating switch 3-pole +N (non-disconnectable) 125 A in polycarbonate housing RSI-3125N\OBP

Insulating disconnect switch – safety and reliability in one device

The RSI-3125N\OBP insulating disconnect switch is a key element of any electrical installation, providing safe disconnection of circuits. Designed to operate with a rated current of 125 A, it is perfect for both industrial installations and public buildings. The polycarbonate construction guarantees mechanical strength and resistance to environmental conditions. The device is particularly useful where reliable isolation of a section of the installation is required during maintenance or repair work.

Construction and application

The RSI-3125N\OBP disconnect switch is a three-pole device with an additional neutral (N) pole, which is non-disconnectable. This means that the neutral is always connected, ensuring circuit continuity when the phases are disconnected. The locking mechanism prevents accidental opening of the disconnect switch under load, increasing user safety. Made with a polycarbonate housing, it provides high resistance to mechanical damage and atmospheric factors. Designed for mounting on a plate or rail, it offers flexibility in choosing the installation location.

Key features and benefits

• High short-circuit resistance: Rated conditional short-circuit current (Iq) at 7.5 kA provides effective protection of the installation against the effects of overloads and short circuits.
• Versatility of application: The possibility of mounting on a plate and the high strength of the housing make the disconnect switch suitable for various working conditions.
• Safety of use: The locking mechanism prevents the disconnect switch from opening under load, minimizing the risk of electric shock and damage to the device.
• Durability and reliability: Made of high-quality materials, it guarantees a long service life and trouble-free operation of the device.
• Compliance with standards: The disconnect switch meets the requirements of PN-EN 60947-3, which confirms its safety and quality.
• Built-in locking mechanism: Provides additional safety when working with the device – prevents accidental opening under voltage.
• Designed for use as an emergency switch and main disconnect switch: Allows it to be used in various electrical installation configurations.
• Rated power AC-23A for three-phase motors up to 30 kW (400V): Allows for safe disconnection of circuits powering motors with significant power.
• Protection degree IP20: Protects against touching live parts and the ingress of solid objects larger than 12.5 mm.

The RSI-3125N\OBP insulating disconnect switch is a solid and reliable solution for every electrician and investor looking for a safe and effective way to disconnect electrical circuits. Its versatility and high quality of workmanship make it an ideal choice for both new installations and modernization of existing power systems.
