FAQs
For installation, use the sprinkler-proof plug-in design within a three-pole, F-frame configuration. Ensure a 125A rating and verify 50% integral grounding. Confirm compatible busway sections, space for the 12.36 in depth and 21.2 in height, and abide by NEMA and UL 857 installation practices to minimize downtime and maximize protection reliability.
The device provides a 125A amperage rating with a 100 kAIC interrupt rating at 240 Vac and 480 Vac, and 25 kAIC at 600 Vac. It is a three-pole, F-frame breaker designed for busway use, with sprinkler-proof plug-in features and 50% integral grounding to simplify grounding schemes.
Yes. The P3BHFD3125SP is explicitly designed as a sprinkler-proof plug-in unit. The 50% integral/housing grounding enhances safety in moist or water-prone spaces, and its NEMA-compliant construction supports reliable protection in such environments.
It carries CSA Certification, ANSI/IEEE Certification, and UL 857. These certifications indicate compliance with recognized safety and performance benchmarks, reducing procurement risk and enabling smoother regulatory approvals for industrial installations.
The unit’s robust fault current rating and sprinkler-proof design reduce unplanned downtime and maintenance costs. Its plug-in architecture simplifies replacements, and the 1-year warranty (or 18 months from shipment) provides a clear post-purchase support window, contributing to lower total cost of ownership in mission-critical power distribution.
