Cylindrical fuse link CH22x58 aM 50A/690V 002652049

Installation and device safety – ETI Polam fuse link

Cylindrical fuse link CH22x58 aM 50A/690V is a reliable element protecting electrical installations and devices against the effects of overloads and short circuits. Designed for use in circuits with motors, it provides effective protection by reacting to current increase and interrupting the circuit in case of dangerous load increase. Its construction and aM characteristic (motor short-circuit protection) make it ideal for industrial and commercial applications where high reliability and protection against damage are required.

Characteristics and application

The fuse link with dimensions 22x58 mm and rated current of 50A, designed to operate at 690V AC, is widely used in protecting various electrical circuits. The aM characteristic provides a delayed response to short-term current surges, which is particularly important when protecting electric motors during start-up – this allows avoiding unnecessary circuit disconnection during normal device operation. The IP20 degree of protection means that the fuse link is protected against finger contact, which increases safety.

Advantages for the installer and end user

• Motor protection: The aM characteristic provides optimal protection of electric motors against overloads and short circuits, minimizing the risk of downtime and costly repairs.
• Versatility: The fuse link is compatible with a wide range of devices and electrical installations with a voltage of up to 690V AC.
• Solid construction: ETI Polam products are characterized by high quality and durability, which guarantees long-term and trouble-free operation. The company has numerous quality certificates (BBJ, VDE, NEMKO, FIMKO, DEMKO) and ISO 9001 and ISO 14000 certificates confirming compliance with international standards.
• Safety: Provides effective protection against electric shock and equipment damage.
• Easy installation: Standard size (22x58 mm) facilitates the replacement of used fuse links.
• Compliance with standards: The product meets the requirements of IEC 60269 standards for fuse links.
