ETC2 A25X90-4 Semiconductor protection fus Datasheet

AMP-TRAP®–Form 101
A25X
SEMICONDUCTOR PROTECTION FUSES
A25X Amp-trap® Form 101 Semiconductor Protection
fuses were designed for heavy duty rectifiers such as
those used in the electro-chemical industry. Originally
designed for diode protection, A25X fuses have been
particularly reliable in heavy duty applications of many
types.
Note: Recommended as replacement fuses only
Features / Benefits
➤ Low l2t minimizes damage to protected component on
short circuit
➤ Controlled arc voltage reduces stress to circuit
components during fuse clearing
➤ Choice of mounting types helps in
equipment design
