Isolating switch FRX 404 4P 125A 406547

Isolator switch – safety and control in the installation

The FRX 404 4P 125A isolator switch is a reliable device designed for safely disconnecting electrical circuits. It finds application in both domestic and industrial installations where reliable isolation and manual control are required. Its solid construction and high technical parameters guarantee long-lasting and trouble-free operation.

Functionality and application

This device plays a key role in ensuring safety during maintenance, repairs or modernization of electrical installations. It can be used as a main, repair, safety and emergency switch. Thanks to the possibility of tripping with additional control equipment (overcurrent or undervoltage release), it provides comprehensive circuit protection. The red control element facilitates identification and operation, and the locking mechanism prevents accidental switching on during service work. Mounting on a plate, 4-hole panel or in distribution boards provides flexibility in choosing the installation location.

Parameters and characteristic features

The FRX 404 isolator is characterized by a rated current of 125A and the ability to operate at a voltage of up to 415V AC. It withstands a short-circuit current of up to 1kA, providing protection against the effects of overloads and short circuits. It has 4 poles and 3 switchable auxiliary contacts, enabling integration with control and signaling systems. The device's construction as a complete element in a housing facilitates installation and ensures readiness for operation immediately after installation. Additionally, the possibility of equipping with a motor drive or voltage release expands the functionality of the device, adapting it to the specific needs of the installation. The width of the device is 6 modules (17.5mm per module).
