3-pole +N isolating switch (disconnected) 125 A in ABS housing with black/green handle RSI-4125N\OBAZC

Isolating switch – safety and reliability in your installation

This isolating switch, designed for safely disconnecting electrical circuits, is a solid solution for both professional installers and end users. It provides effective insulation and protection against accidental contact with live parts. The housing made of durable ABS guarantees resistance to mechanical damage and ensures long-term reliability.

Construction and application

The RSI-4125N\OBAZC isolating switch is a 4-pole (3P+N) device with a rated current of 125 A. It is an emergency switch and main disconnecting switch, ideal for use in electrical installations in residential, commercial and industrial buildings. Thanks to the possibility of mounting on a plate, it can be easily integrated with existing distribution boards. The yellow-red (Y/R) knob provides clear identification and quick operation in emergency situations.

Key features and benefits

• High resistance to working conditions: The housing made of ABS ensures durability and resistance to mechanical damage, and the IP20 degree of protection protects against contact with live parts.
• Safety of use: As an emergency switch and main disconnecting switch, it allows for quick and safe disconnection of the circuit in the event of maintenance or failure.
• Universal mounting: The possibility of mounting on a plate facilitates integration with various types of electrical installations.
• High rated power: The rated operating power for AC-23, 400 V is 30 kW, allowing it to be used in circuits with significant power consumption.
• Short-circuit protection: The rated conditional short-circuit current Iq is 7.5 kA, providing effective protection against the effects of short circuits.
• Solid connections: Screw connection of the main contacts guarantees a secure and durable connection of the wires.
• Suitable for continuous operation: The rated continuous current Iu is 125 A, allowing the device to operate for a long time without the risk of overheating.

Technical parameters in practice

The switch has been designed with demanding applications in mind. The rated short-time withstand current Icw(1s) is 2.5 kA, and the rated ultimate short-circuit current Icm is 7.5 kA – these values demonstrate its ability to withstand temporary overloads and short circuits. Mechanical durability of 8000 cycles and switching durability of 1000 cycles guarantee long device life even with intensive use. The maximum rated operating voltage Ue AC is 690 V, making it a universal solution for many electrical installations.
