Using a bimetal, snap acting disc as the sensing and actuating element, the Klixon SDLA and SDLM series thermal circuit breakers provide trouble–free over current protection for harsh environments.
Available in the three configurations:
•
SLA: Open construction, automatic reset
•
SDLA: Sealed construction, automatic reset
•
SDLM: Sealed construction, manual reset
Applications
•
Main harness, accessory and equipment protection for heavy trucks, busses,
construction equipment, off–road vehicles, and RV’s
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 100% of rated current (1) and trip at 135% of rated current (2).
At 140°F, the same device will hold at approximately 78% of rated current (3), and trip at approximately 115% of rated current (4).
