6-6 | Model 900 ADA / Model 930 Sulfur Pit Analyzers
Spare Analyzer Fuses
AMETEK recommends having on-site spare fuses used in the analyzer.
These fuses do not need to be changed out at regular intervals, but
are necessary in the event that a fuse has blown and a replacement is
required.

Sample and Vent Line Fuses
Part No. Fuse Type
300-9291 6 A

300-9292 10 A
300-9293 16 A
300-6312 20 A
Sample Line fuse (if used) is located at TB3-30 on GP/Div 2 analyzers; TB5-1 on Zone 1 analyzers.
Vent Line fuse (if used) is located at TB3-50 on GP/Div 2 analyzers; TB6-1 on Zone 1 analyzers.
See “Sample/Vent Line Wiring, GP/Div 2 Analyzers” or “Sample/Vent Line Wiring (Disconnect Enclosure), Zone 1
Analyzers” in Chapter 3, or “Lower Cabinet Wiring” drawings in Appendix A.
The Sample and Vent Line fuses are typically not used; however, if
fuse terminals are retrofitted in the field for these temperature zone
circuits, the fuse required will depend on line length, voltage, and
power consumption. If the original factory-installed or retrofitted fuse
blows, remove it to determine the fuse type required.
