Fuse disconnect switch EFD 14 3P+N LED 002560015

Disconnect switch with fuse EFD 14 3p+N LED – reliable installation protection

The disconnect switch with fuse EFD 14 3p+N LED is an element used to safely disconnect electrical circuits and protect against overloads and short circuits. Designed to work with fuse links with dimensions of 14x51 mm, it provides effective protection of the electrical installation in residential and industrial buildings. Its construction allows mounting on a TH 35 rail, which facilitates and speeds up installation.

Functionality and application

This device is used in electrical distribution boards, providing a cut-off point for the circuit for maintenance or repair. Four poles (3 phases + neutral) allow protection of the entire circuit, and the presence of optical signaling (LED) informs about the operation of the fuse link – this is particularly useful for installers when diagnosing problems. The LED signaling facilitates quick identification of a blown fuse, reducing the time needed to locate and fix the failure.

Characteristics and installation

The EFD 14 3p+N LED disconnect switch is characterized by the possibility of connecting wires with a cross-section from 1.5 mm² to 35 mm², which provides a wide range of applications. Mounting is done by snapping onto a standard TH-35 rail, which is a commonly used solution in switchgear cabinets. The operating category AC-22B indicates its intended use for circuits with resistive and inductive loads. The rated voltage AC is 690V, which allows it to be used in installations with different voltages.
