Surge arrester type 1+2 (BC) 50kA 4P DS134R-230 C571504

Electrical installation protection with surge limiters JEAN MUELLER

A type 1+2 (BC) 4P surge limiter with an impressive short-circuit current discharge capacity of 50kA is a key element in protecting the electrical installation from the effects of sudden voltage increases. Model DS134R-230, manufactured by the renowned company JEAN MUELLER, provides comprehensive protection for both installations in residential and commercial buildings. Its design and parameters make it a reliable solution for professionals and end-users looking for solid protection.

Construction and application

This limiter, designed for mounting on a TH35 rail, effectively protects against surges of various origins – both atmospheric (lightning strikes) and those resulting from the operation of devices inside the building. Four poles provide complete protection in three-phase and single-phase circuits. A wide range of connection wire cross-sections (2.5-25 mm²) allows for easy integration with different types of installations. The device is made of durable plastic, which ensures its durability and resistance to mechanical damage.

Advantages and benefits

• High efficiency: The ability to discharge a short-circuit current of 50kA guarantees effective protection even in the event of strong surges.
• Versatility: A type 1+2 (BC) limiter provides protection against both direct lightning strikes (class 1) and transient overvoltages (class 2).
• Easy installation: The design intended for quick mounting on a standard TH35 rail minimizes installation time.
• Wide range of applications: Ideal for protecting electrical installations in residential, commercial and industrial buildings.
• Durability and reliability: Made of high-quality materials, it guarantees long-lasting and trouble-free operation of the device in a wide range of ambient temperatures (-40°C to +85°C).
• Compliance with standards: The product meets applicable safety standards, ensuring a high level of protection.
• Renowned manufacturer: JEAN MUELLER is a company with a long tradition and experience in the production of high-quality electrical installation devices.
