Klixon® 9115 Series Thermal Circuit Breakers
15 to 30 Amp, Precision, Ignition Protected, Waterproof
• |
13 - 30 amps |
• |
Precision thermal circuit breaker |
• |
Suitable for harsh conditions |
• |
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 |
Using a bimetal, snap acting disc as the sensing and actuating element, the Klixon small frame P series thermal circuit breaker provides trouble-free over-current protection for harsh environments.
Similar in construction to the C series device, the P is used in applications such as military vehicles and equipment
where more precise ultimate trip characteristics are required.
Available in two configurations:
|
• |
9115-5: Automatic reset, sealed construction, molded-in electrical terminals, rubber connectors (shells) |
• |
9115-6: Manual reset, sealed construction, molded-in electrical terminals, rubber connectors (shells) |

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). |
