Cylindrical fuse link CH-14 14x51mm gG 16A 500VAC LF416G

Medium current power supply circuit protection

The 14x51 mm cylindrical fuse link is a key component in electrical installations where precise protection against overloads and short circuits is required. This model, designed for use in alternating current (AC) networks, offers a rated current of 16 A, making it suitable for power supply circuits for smaller devices, industrial lighting, or control circuits. Thanks to its gG (general purpose) tripping characteristic, the fuse link reacts effectively to both long-term overloads and sudden short circuits, ensuring the safety of the entire installation. It is worth noting that at the rated current, the power loss is only 2 W, which translates to minimal heating of the element and higher energy efficiency of the system.

Application and technical compatibility

The product has been designed for mounting in standard NH00 type fuse bases or dedicated cylindrical holders. Its ceramic housing not only protects the interior from moisture and dust but also provides resistance to high temperatures generated during operation. A key aspect here is the high short-circuit breaking capacity – according to the manufacturer's data, it reaches a value of 80 kA (per IEC 60898-1 standard), allowing for safe disconnection of current even in the event of very strong short circuits in distribution networks. A rated voltage of up to 690 V AC means that the fuse link can be used in a wider spectrum of applications than typical household devices, including industrial installations with elevated operating voltages.

Benefits for the installer and end user

Choosing this specific model brings measurable benefits to both sides of the installation and operation process:

• Ease of identification: The cylindrical shape and clear parameter markings facilitate quick selection of a replacement during service inspections.
• Low energy losses: During continuous operation at full load (16 A), the fuse link does not generate excessive heat, which protects the contacts in the fuse base from degradation.
• Mounting versatility: The 14x51 mm dimensions are a market standard, guaranteeing compatibility with most fuse holders available on the market.
• Safety during short circuits: The high breaking capacity value (80 kA) eliminates the risk of explosion or damage to adjacent components in the event of a network failure.

When replacing, fuse links with identical electrical and dimensional parameters must absolutely be used to maintain the consistency of the entire installation's protection. Inconsistency in these parameters can lead to improper functioning of the protections or damage to connected devices. It is worth remembering compliance with standards regarding operating voltage and the gG tripping characteristic, which defines the scope of application for this type of protection in general installations.
