Description
Built specifically for industrial switchboards and control panels, this 70A PowerPacT B-frame MCCB provides reliable thermal-magnetic LI protection. It mounts into standard enclosures using integrated DIN rail adapters or unit mounting hardware, serving as an upgraded replacement for legacy FAL36070 breakers. The D-interrupting class delivers 18kAIC at 480VAC, while factory-installed EverLink lugs ensure secure, creep-compensating wire terminations for bare copper or aluminum conductors.Specifications

Product FAQs
7 answersCan the BDL36070 be mounted on a DIN rail?
Yes. Because it is a unit-mount PowerPacT B-frame breaker, it includes integrated mounting clips that fit standard 15 x 35 mm DIN rails. It can also be back-pan mounted using standard screws.
How do the EverLink line and load lugs benefit the installation?
The EverLink terminals feature a patented creep-compensating design. A spring mechanism maintains constant pressure on the wire over time, which prevents the connection from loosening due to thermal cycling and normal cable settling.
What is the recommended tightening torque for the terminals on this breaker?
The EverLink lugs require a tightening torque of 44.25 lb-in (5 N.m) for 14 to 3/0 AWG aluminum or copper conductors.
Can I use the BDL36070 as a direct replacement for an I-Line breaker?
No, the BDL36070 is a unit-mount circuit breaker that uses EverLink lugs on both ends. It will not fit in an I-Line plug-on panelboard. For I-Line installations, you need a breaker with a plug-on jaw connection, such as the BDA36070.
Is this 70A circuit breaker rated for 100% continuous current?
No, this is a standard-rated circuit breaker. Under standard continuous load conditions, it is rated to carry 80% of its maximum 70A capacity.
Does this breaker feature a way to manually test the trip mechanism?
Yes. All PowerPacT B-frame breakers include a push-to-trip button on the front cover. This allows you to manually trip the breaker to verify proper mechanical operation.
Can auxiliary contacts or shunt trips be added to this breaker?
Yes, the PowerPacT B-frame platform supports a wide range of field-installable accessories. These modular accessories, including auxiliary switches and shunt trips, can be snapped directly into the breaker mechanism.
