Disconnect switch FRX 403 125A 3P 406539

Insulation switch – safety and functionality in one

The FRX 403 insulation switch is a reliable device designed for safely disconnecting electrical circuits. It is suitable for both home and industrial installations, providing effective protection against overload and short circuit. Its modular design simplifies mounting in distribution boards, and its solid construction guarantees long-lasting and trouble-free operation.

Application and design features

This device finds wide application as a main, repair and safety switch. The possibility of using it as an emergency switch further increases the safety level of the installation. The design of the switch allows mounting on a plate, in distribution boards and on a TH35 support, providing flexibility during installation. Made of high-quality materials, with a red control element, it is easy to operate and identify. Screw connection of the main contacts ensures a secure and durable connection of the wires.

Technical parameters and user benefits

The FRX 403 switch is characterized by a rated current of 125A and an operating voltage in the range of 36-415V AC. It withstands a short-circuit current of up to 1kA, and its rated operating power for AC-23 is 40kW. The three-pole design ensures complete circuit isolation. Additionally, the possibility of equipping it with auxiliary contacts, releases and drives from the DX³ series allows adaptation of the device to individual installation needs. The locking mechanism prevents accidental switching on or off of the switch during maintenance or service work. The IP20 degree of protection protects against accidental contact with live parts.

• Versatility: Main, repair and safety switch function in one device.

• Safety: The possibility of using it as an emergency switch and the locking mechanism increase the level of protection.

• Installation flexibility: Possibility of mounting on a plate, in distribution boards and on a TH35 support.

• Expandability: Compatibility with DX³ series accessories (auxiliary contacts, releases, drives).

• Durability: Adapted to work in difficult conditions thanks to its solid construction and high strength parameters (short-circuit current 1kA).
