Why Choose the Lovato FB03A1PL Fuse Holder?
The Lovato FB03A1PL is a compact and reliable single-pole cylindrical fuse holder designed for 22 × 58 mm fuse links in industrial electrical protection and power distribution applications. As part of the Lovato Electric FB series, it provides a secure method of installing replaceable fuses within control panels, switchboards and automated machinery.
The FB03A1PL combines a high current capacity with a compact modular design. It is rated at 100 A under IEC standards and up to 125 A under UL and CSA standards, with a maximum rated operational voltage of 690 V AC. This makes it suitable for demanding low-voltage installations where dependable overload and short-circuit protection is required.
Unlike the standard FB03A1P version, the FB03A1PL includes an integrated fuse status indicator, allowing maintenance personnel to identify an operated fuse more quickly. Its one-module format and DIN rail mounting arrangement support straightforward installation while conserving valuable space inside electrical enclosures.

Reliable Fuse Protection with Status Indication
Cylindrical fuse holders provide a safe and stable connection between a fuse link and the protected electrical circuit. When excessive current causes the correctly selected fuse to operate, the circuit is interrupted to help protect cables, control equipment and connected electrical loads from damage.
The integrated status indicator on the Lovato FB03A1PL helps engineers and maintenance teams identify an operated fuse without unnecessary inspection of multiple circuits. This can reduce troubleshooting time and support quicker restoration of machinery and electrical systems following an overcurrent fault.
Typical Applications
- Industrial electrical control panels.
- Power distribution boards and switchboards.
- Motor control centres.
- Automated machinery and production equipment.
- OEM machine building applications.
- Industrial automation systems.
- Electrical circuits requiring visible fuse status indication.
