Why Choose the Lovato FB03A2P Fuse Holder?
The Lovato FB03A2P is a robust two-pole cylindrical fuse holder designed for 22 × 58 mm fuse links in industrial electrical distribution, machinery and automation systems. As part of the Lovato Electric FB range, it provides secure fuse installation and dependable circuit protection against overloads and short circuits.
With a rated current of 100 A under IEC standards and up to 125 A under UL and CSA standards, the FB03A2P is suitable for demanding low-voltage installations. Its 690 V AC nominal voltage supports a wide range of industrial power systems, control panels and distribution assemblies.
The two-pole configuration enables simultaneous protection and isolation of two conductors. Designed for installation on a standard 35 mm DIN rail, the FB03A2P occupies two modular spaces and offers straightforward integration into electrical enclosures. This version is supplied without a blown-fuse status indicator.

Reliable Two-Pole Circuit Protection
The Lovato FB03A2P provides stable electrical connections for two cylindrical fuse links, allowing both protected conductors to be managed within a single modular device. When correctly selected fuses detect excessive current, they interrupt the affected circuits to help protect cables, switching devices and connected equipment.
Its high current and voltage ratings make the FB03A2P suitable for panel builders, machinery manufacturers and industrial engineers requiring reliable fuse protection in compact electrical assemblies. The DIN rail format also enables convenient installation, inspection and fuse replacement during maintenance.
