APC by Schneider Electric Rack PDU Basic Zero U 11 KW 230V (36) C13 & (6) C19 - AP7557NA

APC by Schneider Electric AP7557NA Zero-U Basic Rack PDU 11kW 230V 42-Outlet

Overview

The AP7557NA is a Zero-U basic rack PDU from APC by Schneider Electric designed to deliver 11kW of 230V AC power to high-density rack installations. The Zero-U form factor mounts vertically in the rear of a standard rack enclosure, consuming no rack unit space — every U stays available for equipment. With 42 total outlets (36 C13 + 6 C19), this unit handles mixed loads: C13 ports cover 1U servers, switches, and IP cameras while C19 outlets feed higher-draw devices like high-density NVRs, UPS bypass units, or blade chassis. At 230V input, the 11kW capacity supports fully loaded mid-density racks without requiring a separate sub-panel tap. Operating at 50/60 Hz, the AP7557NA suits both North American and international 230V environments. This is a basic PDU — no remote monitoring, no outlet switching — which keeps cost low and complexity out of the power path for installations where a managed network switch or upstream UPS handles the intelligence layer.

Compatibility

The AP7557NA fits standard 2-post and 4-post open frame racks as well as enclosed cabinets that include a vertical PDU mounting channel. The 70-inch cord length accommodates most standard 42U–47U cabinet depths when routed to a floor-level or overhead 230V feed. C13 outlets are compatible with IEC 60320 C14 power cords standard on 1U rack servers, PoE switches, and network appliances. C19 outlets accept C20 cords used on higher-wattage servers, storage arrays, and enterprise-class UPS units. Physical dimensions of 70 H × 2.2 W × 1.73 D inches confirm Zero-U vertical profile. The 3-foot input cord is short by design — this unit mounts adjacent to the power feed, not across the cabinet.

Installation Notes

Mount vertically in the rear PDU channel of the rack using the integrated mounting bracket. The 2.2-inch width fits standard Zero-U channels without modification. Input cord length is 3 feet — verify your power whip or wall receptacle is within reach before ordering. No tools required for outlet assignment; standard C14/C20 cord insertion applies. Confirm your facility circuit is provisioned for 230V at sufficient amperage to support the 11kW load before commissioning.
