Product FAQs
6 answersHow do I decode the BJL36070 catalog number?
The B indicates the PowerPacT B-frame family, J specifies the interrupting rating tier, L denotes unit mounting with lugs on both the line and load sides, 3 is for three poles, 6 indicates a 600V maximum AC voltage rating, and 070 represents the 70A trip rating.
Can the BJL36070 be mounted on a standard DIN rail?
Yes, this unit-mount PowerPacT B-frame breaker features built-in clips for standard 35mm DIN rail installation. It can also be screw-mounted directly to a backpan.
Is the BJL36070 suitable for reverse feeding?
Yes, this thermal-magnetic breaker is suitable for reverse feeding. It does not contain electronic trip units or directional components that restrict power flow to a single direction.
Is this breaker rated for 100 percent continuous operation?
No, the standard BJL36070 is rated for 80 percent continuous load. Continuous loads should not exceed 56 amps (80 percent of its 70A rating) for periods lasting longer than three hours.
Can the BJL36070 replace legacy Square D F-frame breakers?
Yes, the PowerPacT B-frame series is the modern replacement for legacy Square D FA, FH, and FC frame breakers. However, because the physical dimensions and mounting footprints differ, you may need to modify the backpan or use adapter plates when retrofitting.
Does this breaker support field-installable internal accessories?
Yes, the PowerPacT B-frame supports field-installable internal accessories, including auxiliary switches, alarm switches, shunt trips, and undervoltage releases, which mount securely behind the front cover.
