Cylindrical fuse link SRF CH14X51 SRF20 /600V 002636005

Cylindrical fuse links – protection of installations and devices

The SRF cylindrical fuse link, with dimensions of 14x51 mm, is a safety element protecting electrical circuits against the effects of overloads and short circuits. Designed for use with TVSS surge protectors, it provides an additional layer of protection in installations. Its construction and parameters make it a reliable component for both professional installers and end users.

Construction and operating parameters

The SRF fuse link is characterized by a rated voltage of AC 600V and a short-circuit breaking capacity of up to 200kA. Manufactured by the renowned ETI POLAM, it meets the safety standards of UL 248-1. Its characteristic feature is surge category II and a high value of the breaking integral (17700 A²s) and pre-arcing (5490 A²s), which translates into effective protection of connected devices. The rated current value for this fuse link is 20A.

Application and benefits

SRF fuse links are used in a wide range of electrical installations, including residential, commercial and industrial buildings. They are particularly recommended for protecting circuits powering sensitive electronic devices. Using SRF fuse links allows for:

• Effective protection against overloads: Prevents damage to wires and devices caused by excessive current.
• Protection against short circuits: Quickly interrupts the circuit in the event of a short circuit, minimizing the risk of fire and failure.
• Increased installation reliability: Ensures stable operation of the electrical system by eliminating potential hazards.
• Compatibility with TVSS surge protectors: Enables the construction of comprehensive surge protection systems.
• Easy installation and replacement: Standard size (14x51 mm) facilitates installation and replacement in existing installations.

Additional logistical information: the basic packaging contains 10 pieces, and the transport packaging – 200 pieces. The weight of a single fuse link is 0.029 kg.
