Schneider Electric Class 615 dimensions Overload, Endurance

Compact® NSF and NSJ 150 to 600 A Circuit Breakers

Section 13—Supplementary Technical Information

	Calibration of adjustable instantaneous trip—the circuit breaker must trip within the range of 80–120%
	of the maximum marked tripping current and 75–125% of the minimum marked tripping current.
Overload	• Up to 1600 A—50 operations at 600% of rated current
	• 2000 and 2500 A—25 operations at 600% of rated current
	• 3000–6000 A—three operations at 600% of rated current followed by 25 operations at 200% of
	rated current
	The power factor shall be from to 0.45–0.50 lagging.
Endurance	The circuit breaker must complete an endurance test:
	• Operations at rated current and rated voltage
	• Followed by no load operation.

The power factor shall be 0.75–0.80 lagging.

Interrupting Ability Interrupting ability (Y sequence)—after endurance tests and calibrations are repeated, the circuit breaker completes an opening (O) followed by a close-open operation (O-t-CO), with specified current.

Interrupting ability (Z sequence)—a three-pole circuit breaker rated 240, 480 or 600 V has to complete an opening operation (O) and a close-open operation (O-and-CO) on each pole, at rated voltage, followed by an opening operation (O) using all three poles.
