Cooper Bussmann - 1/8A Slow Acting Glass Fuse for Balboa GS100 Systems - MDL-1/8-R

Cooper Bussmann – 1/8A Slow Acting Glass Fuse for Balboa GS100 Systems

This 1/8A (125 mA) slow acting glass fuse, Cooper Bussmann part number MDL-1/8-R, is a replacement spa fuse for the motherboard of the Balboa GS100 control system. It is a Type T fuse, so it tolerates a short surge instead of blowing straight away, which sets it apart from a fast acting fuse of the same current rating.

Compatibility with the Balboa GS100 spa control system

The MDL-1/8-R is the 1/8A glass fuse used on the motherboard of the Balboa GS100 spa control system. If the fuse on your GS100 board needs replacing, this is the Type T version of the part for that system.

This page covers a single fuse rating only. It is intended for the GS100 motherboard and should not be treated as a general-purpose fuse for other equipment.

What does a Type T slow acting fuse do?

A T-type fuse is a slow acting fuse, sometimes called an anti-surge fuse. It is able to tolerate high current levels for a short time without blowing.

This means that if a sudden change occurs, the fuse does not blow immediately. A fast acting fuse behaves differently, so the two types should not be mixed up when you order a replacement.

How to choose the right replacement fuse
