Eaton P3BHFD3070SP Circuit Breaker Plug-In Unit - UL 857

Sprinkler‑proof plug‑in design. This feature reduces water ingress risk and simplifies maintenance in facilities with active fire suppression. The plug‑in configuration speeds commissioning, minimizes field wiring, and allows quick insertion into busway runs without a full enclosure shutdown. In busy production environments, sprinkler protection translates to fewer service interruptions and more predictable feeder performance for conveyors and pumps. High fault protection ratings. With a 70A rating and 100 kAIC interrupt capability at 240 and 480 Vac, plus 25 kAIC at 600 Vac, the unit supports selective coordination with upstream devices and reduces arc-flash exposure during faults. Applications include manufacturing lines, data centers, and heavy equipment feeders where strong short-circuit performance protects critical loads and speeds recovery. Grounding flexibility. The option of 50% integral or housing grounding simplifies wiring and helps meet varying code requirements. This design accommodates different busway grounding schemes and eases inspection by providing a robust, ready-to-ground path. Coupled with NEMA compliance and UL 857, it supports safer, faster deployments in mixed electrical environments. Three-pole F-frame with busway compatibility. The Pow-R-Way III design aligns with standard busway modules, enabling modular expansion without rewiring. Its plug-in form reduces installation complexity and speeds replacement after maintenance. For contractors and OEMs, this means lower labor costs and tighter project schedules while preserving protective coordination across sections of the installation. Regulatory readiness and lifecycle value. The unit carries IEEE Certified, CSA Certified, UL 857, and NEMA compliance, easing procurement approvals and audits. Backed by Eaton's warranty policy (one year from installation or eighteen months from shipment), the P3BHFD3070SP delivers predictable performance, lower total cost of ownership, and a clear compliance path across industrial markets. Dimensions and installation convenience. The device measures 12.36 in long, 21.2 in high, and 5.43 in wide, with a weight of 25 lb. Its compact footprint fits crowded switchgear spaces and minimizes handling during mounting. Standardized mounting and plug‑in connectivity reduce field wiring, speeding commissioning and ensuring consistent alignment with busway infrastructure.
