Rack PDU

P1000 Series rack power distribution units (PDUs) are available for both vertical and horizontal applications. The PDUs feature 18 AWG cold-rolled steel enclosures, grounding connection points, overload protection, circuit breakers, dual-pole breakers on 208V models, and UL 489-rated circuit breakers on 30A units. In addition, they include two diagnostic LEDs: One indicates that the power is on; the other verifies that the unit is plugged into a receptacle wired with the correct polarity and ground.

Modular bus system

The B400 Series is a modular, overhead, build-as-you-need electrical distribution system for higher load requirements for industrial and high-tech applications. The system provides 400A and 100% continuous duty power. In addition, it offers a 22,000A short-circuit rating for 600VAC and DC systems. Weighing 9.5 lb per ft, the B400 features a cross-section dimension of 5.7 in. × 5.05 in. Available in any length up to 10 ft, it includes optional isolated ground and oversized neutral.

Enclosed disconnect switches

Enclosed Disconnect Switches are offered in both fusible and non-fusible versions. Rated up to 400A, the fusible switches disconnect both the line and load sides of the fuses using two double breaking contacts per pole. Multiple NEMA-type rated enclosures are offered. In addition, switches have SCCRs up to 200kA and use Class CC, J, or L fuses. Other features include easy screw mounting and multiple knockouts for wiring flexibility. The switch handle accepts three padlocks to comply with OSHA lockout/tagout requirements.

3-phase PDU

The 19-in. rack-mount PC3365 Series power distribution unit (PDU) offers 3-phase 120/208V 30A input power via a NEMA L21-30P plug. Power output is 120V, which is distributed through 24 IEC C13 computer-style receptacles, providing 8,640VA of power. The front panel features indicator lights and circuit breakers. Power output is located on the rear through an attached 15-ft power cable, with an integrated cable restraint and management system.
