A type of plug fuse brand name that could handle temporary overloads better than standard fuses, allowing for motor startup surges.
Blend of 'fuse' and 'tron' (from electronics terminology). A brand name that became semi-generic for improved plug fuses with better surge tolerance.
Fusetrons were the clever solution to the motor problem—regular fuses would blow when appliances started up because of brief power surges, so Fusetrons had a delay mechanism.
