Special features
Sprinkler-proof plug-in
Sprinkler-proof plug-in design with a KD frame delivers rugged, space-efficient protection. This combination minimizes downtime by enabling fast, safe replacements in sprinkler zones and busy maintenance windows. For busway installations in sprinkler-prone facilities, this translates to reduced outage time and safer maintenance. High interrupt ratings across voltages (65 kAIC at 240 VAC, 35 kAIC at 480 VAC, 25 kAIC at 600 VAC) ensure withstands fault currents. This protection supports industrial busway networks with high short-circuit energy, reinforcing system reliability and reducing cascading outages. 100% Neutral options and 50% internal grounding provide full neutral current capacity and a robust grounding path. This supports reliable operation in three-pole busway configurations and simplifies compliance. Plug-in design and busway compatibility speed up installation and reduce field wiring complexity. Application: modular power distribution in new builds, plant upgrades, and automation facilities. Certifications and NEMA compliance enable streamlined procurement and QA reviews for regulated environments. Warranty coverage (one year from installation or 18 months from shipment) further lowers lifecycle risk and total cost of ownership.

FAQs
For seamless busway integration, mount the unit on a compatible KD frame, ensure proper alignment with busbar connectors, and secure the Sprinkler-proof plug-in interface prior to energizing. Verify neutral and grounding paths per the 100% Neutral and 50% Internal Ground specifications, and follow vendor torque and clearance guidelines to maintain efficiency and safety during maintenance windows.
The P3BKD3400GNSP delivers 65 kAIC at 240 Vac, 35 kAIC at 480 Vac, and 25 kAIC at 600 Vac. This range supports high fault-current environments typical of large busway systems, enabling reliable interruption across common industrial voltages while maintaining robust protection for connected loads.
Yes. The unit features a sprinkler-proof plug-in design and is intended for use in sprinkler-prone environments. This design reduces the risk of accidental exposure during maintenance, supports rapid replacement without compromising safety, and aligns with typical fire-suppression-compliant facility requirements.
The product carries IEEE Certified, ANSI, CSA Certified, and UL 857 certifications, along with NEMA compliance. These regulatory approvals facilitate procurement, interchangeability with other compliant equipment, and smoother regulatory reviews during audits and commissioning.
Maintenance benefits include rapid plug-in replacements, reduced downtime in sprinkler zones, and straightforward field wiring due to 100% Neutral and 50% Internal Ground. ROI advantages come from shorter commissioning times, lower total cost of ownership, and minimized spare-part inventories thanks to a standardized three-pole 400 A PK (KD) frame compatible with common busway configurations.
