Time-delay fuse link DIII GG 40A 690V~ (BIWTZ) 002313412

Safety and electrical installation protection

Time-delay fuse link DIII 40A 690V is a protective element designed to protect electrical circuits against overload and short circuit. Its construction based on the time-delay characteristic allows for momentary exceeding of the rated current without unnecessary tripping, which is particularly important in the case of devices with motors or other elements generating high starting currents.

Characteristics and application

Fuse link DIII, with a rated current of 40A and a voltage of 690V, is used in industrial and construction electrical installations. The time-delay characteristic (gG) ensures delayed tripping, which minimizes the risk of false alarms caused by short-term current surges. This is crucial for ensuring the continuity of operation of devices sensitive to power interruptions. The black color of the housing makes it easier to identify the fuse link. Size DIII indicates its physical dimensions and compatibility with appropriate fuse holders.

Advantages for the installer and end user

• Overload protection: Protects the electrical installation from damage caused by excessive load.
• Short-circuit protection: Reacts quickly to a short circuit, cutting off the power supply and minimizing the risk of fire or equipment damage.
• Time-delay characteristic: Allows for safe starting of devices with high inrush current, such as electric motors or transformers.
• Versatility: Suitable for a wide range of applications in AC installations with a voltage of up to 690V.
• Easy identification: Black color facilitates visual identification of the fuse link during installation and maintenance.
• Compliance with standards: The fuse link meets the safety requirements specified in relevant standards (no information about specific standards in the provided data).
