EFD 22 3-pole disconnecting fuse combination unit 002570004

Fuse disconnect switch – reliable installation protection

The EFD 22 fuse disconnect switch is an element used to safely disconnect electrical circuits and protect against overloads and short circuits. Designed to work with 22x58 mm fuse links, it provides effective protection for electrical installations in residential, commercial and industrial buildings. Mounting is done on a TH35 rail, which simplifies and speeds up installation.

Construction and application

This device is a three-pole switch (3P), which means it protects all three phases in the circuit. The rated current of 100A makes it ideal for protecting circuits with higher power consumption. The operating category AC-22B indicates its intended use in circuits with inductive loads, such as motors or transformers. Connection of wires with a cross-section of 4-50mm² provides flexibility in choosing the appropriate cables.

It is worth noting the presence of optical indication of the fuse link operation (LED or NEON), which facilitates quick identification of the problem and location of the damage. This is useful for both the installer during servicing and the end user to quickly diagnose the cause of the power failure.

Advantages and benefits

• Versatility: Can be used in both new and modernized installations.
• Safety: Provides effective protection against overload and short circuit – like most circuit breakers in this class.
• Convenient installation: Mounting on a standard TH35 rail minimizes installation time.
• Status indication: Optical indication of operation facilitates fault diagnosis.
• Durability: Made of high-quality materials, guarantees long-lasting and reliable operation.
• Compliance with standards: Meets the required safety standards, ensuring safe use.
• Adapted to inductive loads: Operating category AC-22B allows it to be used in circuits with motors and transformers without risk of damage.

Thanks to its solid construction and precise workmanship, the EFD 22 disconnect switch is a reliable solution for professionals and demanding end users looking for effective protection of their electrical installations.
