Insulating disconnect switch 3-pole +N (non-disconnectable) 160 A in polycarbonate housing RSI-3160N\OBP

Isolator switch – reliable power disconnection

This RSI-3160N\OBP isolator switch is a solid and safe solution for disconnecting electrical circuits. Designed for both industrial installations and public buildings, it provides effective protection against overload and short circuit. The polycarbonate housing guarantees mechanical strength and resistance to environmental conditions.

Construction and application

This switch is a permanently mounted device designed for mounting on a plate. Its main task is to safely disconnect electrical circuits during maintenance, repairs or failures. Thanks to the high rated current of 160A, it is ideal for protecting circuits powering devices with higher power consumption. Equipped with a knob, it enables intuitive operation and visual control of the connection status. As an emergency switch, it allows for quick and effective disconnection of power in crisis situations.

Key features and benefits

• High mechanical resistance: The polycarbonate housing provides durability and resistance to mechanical damage, which translates into a long service life.
• Safety of use: Rated short-circuit current of 10 kA and high insulation (690 V) guarantee safe operation even in difficult conditions.
• Versatility: Available in a 3-pole version with N (non-disconnectable), allowing it to be adapted to different electrical installation configurations.
• Easy installation: Designed for mounting on a plate, which facilitates integration with existing distribution systems.
• Clear status: The clear position of the knob allows for unambiguous visual control of the circuit disconnection status – this is particularly important during service work.
• Application as an emergency switch: Quick disconnection of power when needed minimizes the risk of damage and ensures the safety of people.
• Suitable for continuous operation: Rated continuous current of 160 A enables operation under heavy load without the risk of overheating.

Technical parameters in practice

The RSI-3160N\OBP switch is characterized by a high rated short-circuit current value (Icm = 10 kA), which means that it can withstand short-term current surges without damage. Mechanical durability of 8000 cycles and switching durability of 1000 cycles testify to the reliability of the device even with frequent use. The possibility of connecting wires with a cross-section from 25 to 70 mm² provides installation flexibility. The IP20 protection class protects against accidental contact with live parts. The rated operating power for AC-23, 400 V is 30 kW – which means the ability to protect motors with significant power.
