Modular fuse base for PV systems 2P 10x38mm 32A 1000VDC L502PV

Modular fuse base for photovoltaic systems

This modular fuse base, designed for photovoltaic systems, provides reliable protection against overloads and short circuits. Designed to work with 10x38mm fuse links, it enables safe and efficient operation of the PV installation. The two-pole (2P) design and high voltage resistance up to 1000VDC make it an ideal solution for both professional installers and end users. Compact dimensions allow for space-saving use in the distribution box.

Product features and application

The L502PV fuse base is a component dedicated to photovoltaic installations, providing effective protection against the effects of overvoltage and short circuits. Designed for mounting on a DIN rail, it allows for easy integration with existing electrical infrastructure. High short-circuit breaking capacity (30kA) guarantees system safety in the event of a failure. Use in PV installations requires the use of gPV-characteristic fuse links, ensuring optimal protection of system components.

• Dedicated to photovoltaic systems: Provides optimal protection for specific loads occurring in PV installations.
• High voltage resistance: Adapted to work with voltages up to 1000VDC, which is standard in modern photovoltaic installations.
• Short-circuit breaking capacity: 30kA – guarantees quick and effective disconnection of the circuit in the event of a failure.
• Compact size: Occupies only 2 modules on the DIN rail, making it easy to install even in limited spaces.
• Compatibility with 10x38mm inserts: Standard fuse insert size ensures easy availability of replacements.
• Two-pole design (2P): Provides full protection of the DC circuit.

Technical parameters and construction

The L502PV fuse base is characterized by a solid construction and high quality of workmanship. Made of durable materials, it ensures long-lasting and reliable operation. Adapted to work with wires with a cross-section from 1mm² to 16mm², which provides flexibility when selecting power cables. The IP20 degree of protection provides protection against accidental contact, but does not protect against the effects of weather conditions - therefore, the device should be mounted in a protective housing.

It has two poles and is adapted for a rated current of 32A at a rated DC voltage of 1000V. The rated conditional short-circuit current (Icc) and the rated short-time current (Icw) are 30kA. The device accepts 10x38mm fuse links and has an IP20 protection class and a width of 35mm. It has cable clamps ensuring a solid connection of the wires, and the screw tightening torque should be 2Nm for a correct electrical connection.
