Modular fuse base for PV systems 1P 10x38mm 32A 1000VDC L501PV

Modular fuse base for photovoltaic systems

This Hager L501PV modular fuse base is designed to protect photovoltaic installations. It allows the mounting of 10x38mm fuses with a rated current of up to 32A, providing protection against overload and short circuit in DC circuits with a voltage of up to 1000V. It is a key element in the construction of safe and reliable PV systems, both for professional installers and end users.

Functionality and application

The fuse base is designed for mounting on a TH35 (DIN) rail, which facilitates integration with existing distribution boards. Its construction ensures a solid electrical connection thanks to the use of screw cage terminals. The device is particularly useful in photovoltaic installations where protection against overvoltage and short circuits is required, which may occur as a result of changing weather conditions or component failures. Thanks to the rated operating voltage from 690 to 1000V, this base is compatible with a wide range of PV systems.

Construction features and safety

Made of high-quality materials, the fuse base is characterized by durability and reliability. It has a protection degree of IP20, which means protection against touching with a finger and solid bodies larger than 12.5 mm. The long rotating handle facilitates operation and allows for quick disconnection of the circuit if necessary. The device meets the requirements of IEC/EN 60947-3 standards and directive 2014/35/EU, which guarantees its safety and compliance with applicable regulations. The rated withstand short-circuit current Icw is 30kA, and the prospective short-circuit current Iq is also 30kA – these are important parameters for ensuring effective protection of the installation in the event of a short circuit.
