15 to 30 Amp Precision, Ignition Protected Thermal Breakers
Ignition protected
Waterproof: meets the requirements of MIL-E-13856
Meets requirements of commercial item description A-A-55571 for all federal agencies
Reliable performance: utilizes the accepted snap–acting Klixon disc
Maximum cable efficiency: calibration and thermal disc allow
maximum usage of wiring capacity
In addition to a completely sealed thermal element, the 9115-5 (automatic reset) and 9115-6 (manual reset)
types also have molded–in electrical terminals and are supplied with rubber connectors (shells).

Trip Curve
Approximate Time — Current Characteristics at 77°F (25°C)
Derating Curve
Approximate Effect of Ambient Temperature on Ultimate Trip
Performance characteristics are based on room temperature (77°F). Consult derating curve at left for ambient temperatures
significantly higher or lower than standard room temperature.
Example: At 77°F the device is calibrated to hold at 110% of rated current (1) and trip at 138% of rated current (2).
At 140°F, the same device will hold at approximately 92% of rated current (3), and trip at approximately 120% of rated current (4).
