Why Choose the Lovato FB03A3P Fuse Holder?
The Lovato FB03A3P is a robust three-pole cylindrical fuse holder designed for 22 × 58 mm fuse links in industrial power distribution, machine control and electrical protection systems. Manufactured by Lovato Electric, it provides secure fuse installation and reliable protection for three-phase circuits exposed to overloads and short circuits.
The FB03A3P supports a rated current of 100 A under IEC standards and up to 125 A under UL and CSA standards. Its rated operational voltage of 690 V AC makes it suitable for demanding low-voltage industrial systems, including switchboards, motor control centres and production machinery.
With its compact three-module DIN rail design, the Lovato FB03A3P is easy to integrate into electrical enclosures while providing coordinated protection for all three phase conductors. This version is supplied without an optical fuse status indicator, making it an effective choice for applications where straightforward, dependable fuse protection is required.

Reliable Three-Phase Circuit Protection
The Lovato FB03A3P provides secure electrical connections for three cylindrical fuse links, allowing each phase of a three-phase circuit to be protected within one coordinated device. When excessive current causes a correctly selected fuse to operate, the affected circuit is interrupted to help protect cables, switching devices and connected equipment.
Its high current and voltage ratings make the FB03A3P suitable for panel builders, machinery manufacturers and industrial engineers requiring dependable fuse protection in demanding installations. The DIN rail mounting format also enables convenient installation, inspection and fuse replacement during planned maintenance.
