Disconnect switch FR 303 63A 3P 406467

Insulation switch for safe installation control

The FR 303 63A 3P insulation switch is a reliable device designed to disconnect electrical circuits, providing a safe isolation gap. It is a key element in any electrical installation, allowing maintenance or repair work to be carried out without the risk of electric shock. The device is particularly useful in distribution boards, where it provides easy access and control over individual circuits.

Construction and application

The construction of the switch is based on solid materials, which guarantees its durability and resistance to mechanical damage. Mounting is done on a standard TH35 support, which facilitates integration with existing infrastructure. The three-pole design ensures that the switch effectively disconnects all phases simultaneously, providing complete safety. Thanks to the possibility of connection using comb or pin busbars, the installation is flexible and adapted to different needs. The locking mechanism provides additional protection against accidental switching on during service work.

Key features and benefits

• High short-circuit strength: Rated conditional short-circuit current Iq at 4500 kA provides protection against the effects of overloads and short circuits in the installation.
• Universal mounting: Possibility of mounting on TH35 support and connection using comb or pin busbars facilitates integration with various types of installations.
• Safety of use: Locking mechanism prevents accidental switching on during service work, minimizing the risk of electric shock.
• Intended for distribution boards: It is ideal for use in distribution boards, allowing easy disconnection of individual circuits.
• Application as a main and safety switch: The functionality of the device allows it to be used both as a main switch for the installation and as a safety element against overloads and short circuits.
• Solid construction: The permanently mounted device ensures stability and reliable operation for a long time.
• Wide voltage range: Maximum rated operating voltage Ue AC is 400 V, which makes it compatible with most standard electrical installations.
• Rated current 63A: Allows safe disconnection of circuits with high load.

The FR 303 63A 3P switch is an investment in the safety and reliability of your electrical installation – both for professional installers and end users.
