4-pole isolator switch 63 A with yellow-RED knob. RSI-4063\W03

Isolating switch – safety and reliability in one device

This four-pole isolating switch with a rated current of 63A is a key element of any electrical installation where reliable circuit disconnection is required. It provides safe and controlled isolation, protecting both people and equipment. Equipped with a clear yellow-red knob, it allows for quick and intuitive operation.

Functionality and application

The RSI-4063\W03 switch acts as an emergency switch and main disconnect, making it an ideal solution for securing electrical circuits in residential, commercial and industrial buildings. Its robust construction and high resistance to external conditions guarantee long-lasting and trouble-free operation. A rated current of 63A allows it to handle a wide range of loads.

• Versatile application: ideal for electrical installations in residential, commercial and industrial buildings.
• Safety: emergency switch and main disconnect function ensures quick circuit disconnection when needed.
• Durability: resistant to vibrations, shocks and humid heat – guarantees stable operation even in difficult conditions.
• Intuitive operation: yellow-red knob facilitates identification and quick switching.
• Compliance with standards: designed and manufactured in accordance with applicable safety standards (see "Technical data" section).

Key product features

The switch is characterized by high quality workmanship and a well-thought-out design. The rated operating voltage is 400 V, and the IP20 degree of protection provides protection against contact and ingress of solid objects. The rated short-circuit current is 10 kA (when using a gG 63 A fuse), which increases the safety of the installation. The device is designed for mounting on a TH35 rail, which facilitates its installation and integration with the existing electrical system. It is worth noting the high mechanical durability (10,000 cycles) and connection durability (1500 cycles), which translates into a long service life of the device.
