Cylindrical fuse link PV CH10x38 gPV 20A/1000V DC UL 002625108

Fuse link for photovoltaic installation protection

ETI Polam CH10x38 gPV 20A/1000V DC fuse link is a protective element designed to protect circuits in photovoltaic installations. It has been specifically designed with the unique requirements of these systems in mind, providing effective protection against overloads and short circuits. Its gPV (photovoltaic) design allows for a quick and safe response in the event of a failure, minimizing the risk of damage and fires.

Construction and application

The fuse link is characterized by a cylindrical construction with dimensions of 10x38 mm. It is compatible with dedicated fuse holders, which facilitates installation and replacement. The use of the gPV characteristic means that the fuse link reacts optimally to currents occurring in photovoltaic installations – slower to short-term current surges during inverter start-up, and quickly to long-term overloads. This ensures reliable protection without unnecessary circuit disconnection. This is particularly important in PV systems, where sudden disconnections can lead to energy losses and disruptions in system operation.

Key features and benefits

• PV installation protection: The special gPV characteristic provides optimal protection for photovoltaic circuits, taking into account the specifics of inverter and solar panel operation.
• High short-circuit breaking capacity: A short-circuit breaking capacity of 10 kA (DC) guarantees effective circuit interruption in the event of a short circuit, protecting the remaining elements of the installation.
• Rated voltage 1000V DC: Designed for photovoltaic installations with a voltage of up to 1000V DC.
• Compliance with standards: Meets the requirements of IEC 60269-6, UL 2579 and UL 248-1 standards, confirming its safety and reliability. It has UL certificate E347771.
• Compact dimensions: Dimensions of 10x38 mm allow for easy mounting in standard distribution boards and enclosures.
• Low power loss: Power losses of 1.3W (at 0.7xIn) minimize energy losses in the circuit.
• Solid construction: Made of high-quality materials ensuring durability and reliable operation for a long time.
• Wide range of applications: Ideal for protecting photovoltaic modules, inverters and other elements of the PV installation.

The rated current is 20 A, the rated DC voltage is 1000 V, and the characteristic is gPV. The short-circuit breaking capacity reaches 10 kA (DC), and the time constant L/R is 2 ms. The fuse link has dimensions of 10 x 38 mm.

Thanks to these features, the ETI Polam fuse link is a reliable solution for professional installers and end users looking for effective protection of their photovoltaic installations. Its solid construction and compliance with standards guarantee long-term and safe operation of the PV system.
