4-pole isolator switch 160 A in polycarbonate housing with black/yellow handle RSI-4160\OBPZC

Isolator switch – reliable power disconnection

This four-pole isolator switch with a rated current of 160A is a key element of any electrical installation where safe and reliable disconnection of the circuit is required. Equipped with a solid polycarbonate housing and an intuitive yellow-red knob, it provides both durability and ease of use. This device is designed to operate in systems up to 690V, guaranteeing safety and reliability in demanding conditions.

Functionality and application

This isolator switch serves as an emergency switch and a main switch, allowing for quick and effective isolation of the circuit when maintenance, repair or emergency work is required. Its design allows for mounting on a plate, making it easy to integrate with existing distribution boards. The rated operating current Ie in category AC-23A is 125A at 400V, making it suitable for protecting various loads, including asynchronous motors with a power of up to 30 kW. Screw connections ensure secure and durable wire connections.

Safety and technical parameters

The device's construction meets high safety standards, confirmed by the rated short-circuit current Icm of 10 kA and the ability to withstand short-circuit current for a short time Icw(1s) at 3.2 kA. The IP20 protection class provides protection against accidental contact. It is worth noting its ability to operate in difficult conditions – it withstands vibrations and shocks in accordance with IEC 60068-2-6 and IEC 60068-2-27 standards. The locking mechanism (none) and the lack of a built-in motor drive simplify the design and increase the reliability of the device. Additionally, this isolator switch is designed for permanent mounting, ensuring stability and long-term operation.
