Cylindrical fuse link CH22x58 aM 125A/500V 002652053

Safety and protection of electrical installations

Cylindrical fuse link CH22x58 aM 125A/500V is an element used to protect electrical circuits from the effects of overloads and short circuits. It is a key component in ensuring the reliable operation of installations, both in domestic and industrial applications. This fuse link, with dimensions of 22x58 mm, is characterized by a rated current of 125A and is designed to operate in circuits with a voltage of up to 500V AC.

aM characteristic and its significance

The fuse link has an aM characteristic (motor protection), which means it is specifically designed to protect electric motors. This characteristic allows for momentary exceeding of the rated current during motor start-up, without unnecessarily disconnecting the circuit. This allows the motor to start freely, and the fuse link will only operate in the event of a serious short circuit or overload. This is important for installers who often deal with applications requiring motor protection.

Construction and application

Cylindrical fuse links, such as CH22x58 aM, are widely used in electrical switchboards and in power circuits for various devices. Their construction is based on a fusible element that melts under the influence of excessive current, interrupting the circuit and protecting the remaining elements of the installation from damage. They are indispensable wherever fast and effective protection against the effects of electrical failures is required. It is important to select the correct fuse link for a specific application – the aM characteristic is particularly important when protecting motors.
