FAQs
The P3BLW3630GN is designed for Pow-R-Way III busway systems and is a three-pole plug-in unit engineered to mount directly on compatible Pow-R-Way III sections. Ensure the busway segments are rated for 630A and match the unit’s L frame and plug-in mounting to achieve proper coordination and performance. This minimizes wiring and speeds installation in new or retrofit projects.
It is a 630A three-pole circuit breaker with interrupt ratings of 85 kAIC at 220–240V, 45 kAIC at 380–415V, and 20 kAIC at 660–690V. The design features 100% neutral and 50% internal grounding, making it suitable for protecting busway circuits while maintaining accurate neutral performance and safe fault paths.
Yes. It carries IEEE Certified, CSA Certified, ANSI, and UL 857 listings and is NEMA compliant. These certifications support broad regulatory acceptance, interoperability with other third party components, and safer integration into industrial power distribution systems.
Dimensions are 19.65 in (length) x 41.91 in (height) x 10.15 in (width) with a weight of 75 lb. The unit is a plug-in design for Pow-R-Way III busways, which simplifies wiring and reduces field labor. Plan for adequate clearance around the unit for service access and verify the busway section compatibility during layout and space calculations.
