8-pole isolator switch 125 A in ABS housing RSI-8125\OBA

Disconnect switch – reliable power disconnection

Disconnect switch RSI-8125\OBA is a solid device designed for safely disconnecting electrical circuits. Equipped with an ABS housing, it provides durability and resistance to mechanical damage. It is a key element in electrical installations, guaranteeing safety during maintenance, repairs and failures. 8 poles allow disconnecting multiple circuits simultaneously, which is particularly useful in more complex installations.

Construction and application

The device is designed for panel mounting and serves as an emergency switch and main disconnect. Its construction based on a locking mechanism (although it is not possible to activate it) and a knob ensures convenient and reliable operation. The continuous rated current of 125 A and the short-circuit breaking capacity of up to 7.5 kA make this disconnect switch perfect for protecting installations against overloads and short circuits. The possibility of connecting wires using screw connections facilitates installation and ensures a reliable electrical connection.

Key features and benefits

• High mechanical resistance: The ABS housing protects the internal components from damage, ensuring long-term operation of the device.
• Safety of use: The emergency switch and main disconnect function increases the safety of working with the electrical installation.
• Versatility: The possibility of panel mounting allows flexible adaptation to different installation configurations.
• Ability to work in difficult conditions: Rated operating voltage up to 690 V and high resistance to vibration, shock and humid heat ensure reliable operation in demanding industrial and commercial environments.
• Short-circuit protection: The rated conditional short-circuit current of 7.5 kA effectively protects the installation from the effects of short circuits.
• AC-23A rated power: The ability to work with motors up to 30 kW (at 400 V) makes it suitable for various industrial applications.
• Protection class IP20: Provides protection against accidental contact with live parts (front side).

Technical parameters in practice

The RSI-8125\OBA disconnect switch has been designed with demanding applications in mind. For example, the short-time withstand current of 2.5 kA means that the device can withstand short-term voltage surges without damage, which increases its reliability in the event of sudden load jumps. Mechanical durability of 8000 cycles and switching durability of 1000 cycles guarantee long device life even with intensive use. The possibility of connecting wires with a cross-section from 25 mm² to 70 mm² ensures compatibility with various types of electrical installations.
