Fuse 229/230 Series
Our standard 229 and 230 Series Slo-Blo
®
fuses meet the demanding
requirements of the Telecom industry. These Fuses combine
conventional overcurrent protection with the ability to withstand high cur-
rent, short duration pulses. These fuses comply with the short circuit
requirements of UL 1459 for telephone equipment. Insulating Sleeve
Option available. We have characterized these fuses for the Telecom
industry requirements as shown below.

The 2AG Indicating Slo-Blo
®
fuse instantly identifies itself upon
o
pening by showing a discoloration of its glass body. Guesswork
and time consuming circuit testing are eliminated. This unique
design offers the same quality performance characteristics as
the standard 2AG fuse design.
* When ordering the 2AG Indicating Slo-Blo Fuse, an ‘S’ is
required after the catalog number.
