Cylindrical fuse link CH14x51 aM 12A/690V 002652029

Safety and protection of electrical installations

Cylindrical fuse link CH14x51 aM 12A/690V is an element used to protect electrical circuits against overloads and short circuits. Its construction based on the aM characteristic (motor protection) makes it particularly useful in installations powering electric motors, where high starting currents occur. In the event of exceeding the permissible current, the fuse link melts, interrupting the circuit and protecting the connected devices.

Characteristics and application

Cylindrical fuse links CH are a proven safety element, used in both industrial installations and residential construction. Model CH14x51 with a rated current of 12A and a voltage of 690V is designed to operate in alternating current (AC) circuits. The aM characteristic provides a delayed response to short-term current surges, allowing for safe motor starting without unnecessary circuit tripping. This solution avoids downtime in device operation.

Construction and parameters

The fuse link has dimensions of 14x51 mm, making it compatible with appropriate holders and enclosures. It is made of high-quality materials – a body of porcelain C110 or C410 and contacts of Cu Zn 28 with the addition of Ag. Such a combination ensures reliable operation and long service life. It is worth noting the versatility of this model – it can operate in both 500V and 690V installations. The weight of a single fuse link is approximately 18.6g.
