Cylindrical fuse insert CH-22 22x58mm gG 16A 690VAC LF516G

Fuse link for protection of industrial installations and switchboards

The 22x58 mm fuse link is a key component in electrical protection systems, designed for operation in alternating current (AC) circuits with a voltage up to 690 V. Constructed from ceramic, the device exhibits high mechanical and thermal resistance, which is essential in industrial environments. Thanks to its gG (general-purpose) tripping characteristic, this element effectively protects installations against the effects of short circuits and prolonged overloads. It is a universal solution suitable for both main switchboards and smaller auxiliary circuits where precise protection of cables and equipment is required.

Application and Operating Principles

This fuse is intended for mounting in CH-22 type fuse holders. Its primary function is to automatically disconnect the power supply when current values exceed permissible limits. It is important to note the breaking capacity of 80 kA – this means the device can safely interrupt a short-circuit current of this magnitude without the risk of explosion or damage to adjacent installation components. This is particularly important in modern power networks where short-circuit currents can be very high.

For the installer, information regarding power losses is also significant. At a rated current of 16 A, the fuse link dissipates approximately 2.1 W of heat. This means that during continuous operation under full load, the element will become slightly warm, which should be taken into account when designing ventilation in compact distribution enclosures. However, low power losses contribute to increased energy efficiency of the entire system and reduced thermal load on neighboring components.

Key Features and Operational Benefits

The selection of this model results from the combination of proven construction solutions with the requirements of contemporary safety standards. The ceramic housing ensures electrical insulation even at high operating voltages, while the precisely selected fusible alloy guarantees repeatability of tripping time.

• Versatile protection: The gG characteristic allows protection of both supply cables and load equipment against damage resulting from overload or short circuit.
• High reliability: A breaking capacity of 80 kA ensures reliable operation even in the event of high-power short-circuit faults.
• Dimensional compatibility: The standard 22x58 mm size facilitates replacement and installation in existing protection systems without the need to upgrade fuse holders.
• Continuous operation: The device is designed for operation in AC networks with a frequency of 50-60 Hz at a rated voltage of 690 V.

The electrical parameters of the device have been optimized for safety: the rated current is 16 A, and the maximum operating voltage reaches 690 V AC. In the event of a short circuit, the device demonstrates the ability to safely interrupt currents up to 80 kA, eliminating the risk of installation damage during high-level short circuits. It should be noted that there are minor power losses of approximately 2.1 W under full load, and the ceramic construction of the fuse element ensures durability in harsh environmental conditions. Thanks to these features, the fuse link forms a solid foundation for the safe operation of electrical installations, minimizing fire risks and equipment failures. This solution is dedicated to professionals who value ease of installation and reliable performance under demanding operating conditions.
