The Bussmann FMX40LP is a low-profile 40-amp maxi fuse designed with female terminal connections for secure circuit protection in automotive, marine, and powersports electrical systems. This time-delay fuse provides reliable overcurrent protection while allowing temporary harmless current surges to pass through without interrupting power.
Key Features:
This fuse is commonly used in high-current applications such as alternator circuits, power distribution systems, winches, audio amplifiers, and other accessories requiring robust overcurrent protection. The time-delay feature makes it ideal for inductive loads that draw higher current during startup.
