Fuse disconnect switch EFD 14 3P+N 002560005

Fuse disconnect switch for protecting electrical installations

The EFD 14 3p+N fuse disconnect switch is a reliable safety element for electrical installations, protecting against the effects of short circuits and overloads. Designed to work with cylindrical fuse links with dimensions of 14x51 mm, it provides effective protection for electrical circuits in residential, commercial and industrial buildings. The design allows for quick and easy mounting on a TH35 rail, simplifying installation and servicing.

Features and application

This disconnect switch, manufactured by ETI POLAM, is a new generation device combining proven solutions with modern functionalities. Designed to operate with a rated current of 50A and a voltage of 690V (AC), it meets the requirements of category AC-22B. The wide range of applications includes both newly built and modernized installations. Thanks to the possibility of sealing the ON and OFF position levers, it provides additional safety and prevents accidental switching of the circuit.

• Overload and short-circuit protection: Protects the electrical installation from damage caused by excessive load or short circuit.
• Mounting on TH35 rail: Allows for quick and easy mounting in electrical switchboards.
• Fuse size: Compatible with fuse links with dimensions of 14x51 mm – industry standard.
• Optical indication: Has optical indication of fuse link operation (LED or NEON), which facilitates identification of a blown fuse.
• Possibility of sealing: Provides additional security by preventing unauthorized change of the switch status.
• Durable plastic: The housing is made of a material resistant to high temperatures, which increases durability and safety of use.
• Four-pole design (3P+N): Provides complete circuit protection, including the neutral wire.
