Isolator switch FRX 303 40A 3P 406535

Isolator switch – reliable power disconnection

This three-pole FRX 303 isolator switch with a rated current of 40A is a key element of any electrical installation where safe and reliable circuit disconnection is required. Designed for durability and functionality, it provides effective protection for both installers and end-users.

Safety and functionality in one

The FRX 303 switch is designed for mounting in distribution boards, making it easy to integrate with existing infrastructure. Its construction as a permanently mounted device guarantees stability and reliable operation for a long time. The locking mechanism provides additional protection against accidental circuit opening during operation or maintenance. The rated short-circuit current of 4500 kA demonstrates its resistance to sudden voltage and current surges, which translates into a higher level of safety for the entire installation.

Application and benefits

This isolator switch is perfect as:

• Main switch: allows complete disconnection of power in the event of a failure or maintenance work.
• Safety switch: ensures safe disconnection of devices before starting repairs or adjustments.
• Industrial installation element: ideal for use in production plants, workshops and other industrial facilities.

Thanks to screw connections, installation is simple and intuitive, and the IP20 degree of protection provides basic protection against accidental contact. The maximum rated operating voltage of 400V makes it compatible with most standard electrical installations. It is worth remembering that the device does not have a built-in motor drive or the possibility of connecting an optional drive.
