Fuze M520A1 is assembled with Booster M125A1 which provides a delay arming distance of 200 feet. Fuze M520 uses Booster M125 which provides 150 feet. Turning the lower cap to set desired time in seconds prior to detonation simultaneously rotates the timing disk of the internal clockwork mechanism to correspond.

This is the American M520, a High-Explosive (HE), setback and centrifugally armed, Mechanical-Time Super-Quick (MTSQ) fuze used to achieve either airburst or Super-Quick (SQ) Impact (IMP) detonation of the projectile with a copy made in Italy and designated the M520C4.

Fuze M520 uses Booster M125 which provides 150 feet. These dual purpose, mechanical time and superquick fuzes are used with ammunition calibers 90mm through 280mm, except 175mm. The fuze can be used to achieve either airburst or superquick impact detonation of the projectile,

This dual purpose proximity fuze was developed in the 1960's for 81mm mortar use. It is selectable for Point Detonating or Proximity, designed to detonate the round between 3 and 30 ft above the target, depending on the terrain.

These fuzes are fitted to various 60mm and 81mm mortar cartridges as issued. M52 series fuzes are single action superquick types with a direct action firing device.

The M571, M592 and M711 fuzes are hand settable XM137 booster and is assembled only to the M413 105mm HE with a plunger which provides locking of lower cap in flight and

This specification covers the metal parts for three types of fuzes designated as Fuze, Point Detonating, M525, Fuze Point Detonating, M526, and Fuze, Point Detonating, M527B1 used to 60MM and 81MM Mortar ammunition.
