Features/Benefits
?Low l 2t 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 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
?UL Recognized Component ?AC: UL Guide No.JFHR2 (10-250A)
Approvals APPLICATIONS:
?
Protection of 250 volt heavy duty rectifiers and similar heavy power supplies
