Ultra-fast fuse link CH14 AR 16A / 690V 002635009

Ultra-fast fuse links CH14 – protection of installations and devices

CH14 fuse links are safety elements that protect electrical circuits against the effects of overloads and short circuits. This model, with a rated current of 16A and a voltage of 690V, is distinguished by its ultra-fast characteristic, making it an ideal choice for protecting particularly sensitive devices and installations. The CH14 AR 16A/690V fuse link is designed to work with automatic circuit breakers and other safety elements, providing comprehensive protection.

Design and application

The CH14 fuse link is characterized by its compact dimensions – 14x51 mm – which makes it easy to install in limited spaces. It has been designed for quick and effective circuit disconnection in the event of a dangerous current increase. It works particularly well in applications requiring high selectivity and a fast response to fault currents. The AC short-circuit switching capacity is as high as 200kA, and DC 50kA, which guarantees safety even in the event of serious failures.

Advantages and benefits

• Ultra-fast aR characteristic: ensures a lightning-fast response to fault currents, minimizing the risk of damage to connected devices. The aR characteristic is particularly important for protecting semiconductors and other electronic components sensitive to overvoltage.
• High short-circuit switching capacity: 200kA AC and 50kA DC guarantee effective protection even in the event of large short-circuit currents.
• Compact dimensions: 14x51 mm make it easy to install in tight spaces, typical of electrical switchboards.
• Compliance with standards: the product meets the requirements of IEC 60269-4, which confirms its safety and reliability.
• Application in semiconductor protection: dedicated to protecting electronic circuits from damage caused by overvoltages.
• Low power loss: thanks to the design minimizing energy losses (Pd = 5.5W), the fuse link ensures efficient operation without unnecessary heating.
• Total Joule’s let-through: a value of 75 A²s indicates high energy efficiency during the short-circuit switching process.
