•	Ignition protected
Using a bimetal, snap acting disc as the sensing and actuating element, the large frame P Series thermal circuit breaker provides trouble free over current protection for harsh environments. The P Series is available in two configurations:
•	PDLA: Sealed construction, automatic reset
•	PDLM: Sealed construction, manual reset
Applications
•	Military vehicles and equipment where precise ultimate trip characteristics are required
General Envelope Dimensions Nominal dimensions provided for reference only.

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).
