8-pole isolator switch 125 A with yellow-RED knob. RSI-8125\W03

Isolating switch – reliable power disconnection

This 8-pole isolating switch with a rated current of 125 A is a robust solution for safely disconnecting electrical circuits. Equipped with a handle with a red indicator, it provides easy and intuitive operation. It is a device designed for both industrial and commercial building applications where certainty and reliability are required.

Design and application

The RSI-8125\W03 switch is designed for plate mounting, making it easy to integrate into existing installations. Its construction based on a durable fixed mounting structure guarantees long-lasting and trouble-free operation. As an emergency switch and main switch, it is a key element in electrical safety systems. It is intended for disconnecting circuits in emergency situations, during maintenance or repairs, ensuring complete safety for people working on the installation. The rated operating power for AC-23, 400 V is 30 kW, making it suitable for protecting various loads.

Key features and benefits

• High resistance to environmental conditions: meets IEC standards for resistance to vibration, shock, damp heat and salt mist – which translates to reliability even in harsh working conditions.
• Safety of use: As an emergency switch, it provides quick and effective power disconnection in hazardous situations.
• Easy operation: The handle with a red indicator enables intuitive and quick control of the switch.
• Wide range of applications: Suitable for protecting circuits with a continuous current of up to 125 A and withstands a short-circuit current of up to 7.5 kA.
• Universal mounting: Plate mounting allows easy integration with existing distribution systems.
• Durability: Made of high-quality materials ensures a long service life of the device (8000 mechanical cycles and 1000 switching cycles).
• Protection against overload and short circuit: Protects the circuit from damage caused by excessive load or short circuit – like most switches in this class.

Technical parameters in practice

The RSI-8125\W03 switch is characterized by high technical parameters, which translate into its reliability and safety of use:

• Rated continuous current (Iu): 125 A – determines the maximum current that the switch can conduct for a long time without overheating.
• Rated conditional short-circuit current (Iq): 7.5 kA – indicates the ability of the switch to withstand short-term overvoltages caused by a short circuit in the network.
• Rated operating voltage (Ue AC): 690 V – the maximum voltage at which the switch can operate safely.
• Cross-section of connection cables: 25…70 mm² – allows connection of cables of different thicknesses, adapting to the requirements of a specific installation.

This isolating switch is an investment in the safety and reliability of your electrical installation. It provides effective protection against overloads and short circuits, and also allows quick and safe disconnection of power when needed.
