3-pole + N isolator switch (non-disconnectable) 125 A in polycarbonate housing with Yellow/Green knob RSI-3125N\OBPZC

3-pole isolator switch + N 125 A in a polycarbonate housing

This RSI-3125N\OBPZC isolator switch, with a rated current of 125 A, is a reliable solution for safely disconnecting electrical circuits. Designed for both industrial and commercial applications, it provides effective protection of installations and equipment. Made of high-quality polycarbonate, it guarantees durability and resistance to mechanical damage. The yellow-red (Y/R) knob allows for intuitive operation and visual identification of the switch status.

Construction and application

This switch is designed to operate as an isolator, main or emergency switch. Its construction allows for mounting on a plate, which facilitates integration with existing distribution systems. Equipped with screw connections, it ensures a secure and stable connection of the wires. Suitable for operation at a maximum voltage of 690 V AC and has high resistance to environmental conditions, including vibrations and shocks. The rated operating power for AC-23 is 30 kW at 400 V.

Key features and benefits

• High reliability: Rated short-circuit current withstand of 7.5 kA guarantees safe operation in the event of a short circuit.
• Versatility: Can be used as an isolator, main or emergency switch, adapting to different installation needs.
• Durability: The housing made of polycarbonate provides resistance to mechanical damage and atmospheric factors.
• Safe operation: The knob with a lock prevents accidental opening of the switchgear door in the ON (I-ON) position.
• Easy installation: Plate mounting allows for easy integration with existing distribution systems.
• Wide range of applications: Designed for installation in industrial buildings, commercial premises and electricity distribution networks.
• Compliance with standards: Meets the requirements of PN-EN 60947-3 standard, which confirms its safety and quality.

Technical parameters in practice

A continuous rated current of 125 A allows for safe circuit loading without the risk of overload. Characteristic C allows it to react more slowly to short current surges, therefore it tolerates starting devices with a motor well. The rated operating power for AC-23A is 30 kW at 400 V – this is sufficient for most standard industrial applications. Vibration and shock resistance makes it suitable for harsh working conditions.
