Modular fuse base 3P for cylindrical fuse L58 22x58 mm 125A 690VAC LR703

Modular fuse base – reliable installation protection

This three-pole fuse base, designed to work with L58 cylindrical fuses with dimensions of 22x58 mm and a current of up to 125A, is a key element in protecting the electrical installation. Designed for use in both commercial and domestic facilities, it provides effective protection against overloads and short circuits. DIN rail mounting simplifies quick and trouble-free installation in distribution boards.

Solid construction and high functionality

The base is characterized by a solid, enclosed construction, which increases safety and minimizes the risk of accidental contact with live parts. A width of 6 modules allows for efficient use of space in switchgear cabinets. Made of high-quality materials, it guarantees long-lasting and trouble-free operation. Please note that the product is supplied without a fuse – the selection of the appropriate current value depends on the specifics of the protected circuit.

Specification and application

The LR703 fuse base meets the standards EN/IEC 60269-2, EN/IEC 60269-2-1 and EN/IEC 60947-3, which confirms its compliance with applicable safety standards. It is intended for use in installations with a rated voltage of 690V AC and a frequency of 50Hz. Thanks to the possibility of sealing, it provides additional protection against unauthorized access and manipulation. The use of screw terminals allows the connection of wires with a cross-section from 2.5 mm² to 50 mm² (rigid) and from 2.5 mm² to 35 mm² (flexible). The degree of protection IP20 provides protection against accidental contact, but does not protect against the effects of water.
