£29.86
The Lovato FB03A1P is a dependable single-pole cylindrical fuse holder designed for 22 × 58 mm fuses used in industrial power distribution, machinery and electrical control systems. As part of the Lovato Electric FB range, it provides a secure and accessible method of installing replaceable fuses for overload and short-circuit protection.
The FB03A1P is rated for currents of 100 A under IEC standards and up to 125 A under UL and CSA standards. Its 690 V AC rated voltage makes it suitable for demanding low-voltage industrial installations, while its compact single-module design helps conserve valuable space inside electrical panels.
Designed for installation on a standard 35 mm DIN rail, the Lovato FB03A1P offers straightforward panel integration and convenient fuse replacement. The holder is supplied without a blown-fuse status indicator and features an IP20 frontal protection rating for use inside suitable electrical enclosures.
Cylindrical fuse holders provide a secure connection between the fuse link and the protected electrical circuit. When a correctly selected fuse detects excessive current, the fuse element interrupts the circuit to help protect cables, switching equipment and connected machinery from damage.
The Lovato FB03A1P is particularly suitable for panel builders and machinery manufacturers requiring a high-current, single-pole fuse holder with a compact DIN rail format. Its finger-safe frontal construction and internationally recognised approvals support reliable integration into industrial electrical systems.
