Cylindrical fuse link CH-22 22x58mm gG 32A 500VAC LF532G

Protection of power circuits in industrial and household installations

Cylindrical fuse cartridge with dimensions of 22x58 mm is a key element for the safety of electrical installations, designed to operate in alternating current circuits. The device, designated as model CH-22, features a gG tripping characteristic, which means full capability to protect against overloads and short circuits. Thanks to this solution, it can be used not only in general circuits but also where devices with high starting currents are present, such as motors or transformers. The rated current of 32 A allows safe current flow in standard distribution circuits, and the rated voltage up to 690 V (according to manufacturer data) ensures a wide range of applications in low-voltage systems.

Ceramic construction and operational parameters

The construction of this fuse is based on a ceramic body, which is the standard for elements requiring high thermal and mechanical resistance. Inside there is a fuse element that, in case of current value exceedance or short circuit occurrence, melts, cutting off the power supply. It is worth noting the low power loss – at rated current it is approximately 3.5 W. This parameter is important for installers caring about the energy efficiency of switchgear and minimizing heating of components in tight enclosures. High short-circuit breaking capacity (up to 80 kA) guarantees that even at very high short-circuit currents, the fuse will operate without risk of explosion or damage to neighboring components.

Key features of this model result directly from its construction and electrical parameters. The gG characteristic ensures that the cartridge effectively protects against overloads and short circuits, making it a universal choice for general circuits and those with inductive devices. Standard size 22x58 mm (type CH-22) ensures full compatibility with most available fuse bases, facilitating installation and replacement in existing switchgear. Low power loss value of 3.5 W limits heating of the cartridge during long-term operation under full load, which is particularly important in tight enclosures. Additionally, the use of a ceramic body provides high temperature resistance and mechanical stability even in demanding working conditions.

Installation and operating conditions

Installation of the cartridge requires using an appropriate fuse base of type CH-22. Due to the gG characteristic, this element does not have a blown fuse indicator (unlike some aM models), so checking the condition requires visual inspection or use of a meter after removing the cartridge from the base. The fuse is intended for operation in dry or normal environments, according to IEC 60269 standards. Its versatility makes it a preferred choice for both modernization of older switchgear and new installations requiring reliable overcurrent protection with a value of 32 amperes. Regular inspection of the technical condition of protective elements should be remembered in order to maintain the continuity of installation protection.
