Safe power disconnection – Legrand FR 304 isolator

The Legrand FR 304 isolator is a reliable device designed for the safe disconnection of electrical circuits. Its four-pole design and rated current of 40A make it ideal for use in building and industrial installations. Its robust construction and locking mechanism guarantee safe operation, and the ability to mount on a DIN rail simplifies integration with existing systems.

This isolator not only provides effective isolation but also allows for easy and convenient switching of circuits. This is crucial in situations requiring maintenance, repairs, or emergency power outages. Thanks to its high short-circuit strength (4500 kA), it can withstand sudden voltage surges, protecting connected devices and the electrical installation.

• Versatile application: Excellent for installation in distribution boards as a main or safety isolator.
• Safety first: Features a locking mechanism that prevents accidental switching on during maintenance work.
• Durable construction: Permanently mounted device made of high-quality materials ensures long-lasting and reliable operation.
• Easy installation: Designed for mounting on DIN rail TH35, which greatly simplifies the installation process.
• Short-circuit protection: Rated conditional short-circuit current at 4500 kA provides protection against the effects of overloads and short circuits.
• Durability: Adapted to work in a wide temperature range – from -25°C to 70°C – and has high mechanical durability (20,000 cycles).

The FR 304 isolator features a screw connection of the main contacts, ensuring a secure and stable connection of the wires. The IP20 degree of protection guarantees protection against accidental contact, increasing safety. The device complies with IEC 60947-3 (AC 23 A) standards, confirming its high quality and reliability. Its compact dimensions (70.8 mm width, 88.9 mm height and 76.4 mm depth) allow for easy integration even in limited space of distribution boards.
