Tripp Lite PC975-R Pdu Epo 2U 24A 3-phase L21-30

Product Description

The TRIPP LITE PC975-R is a 2U rackmount power distribution unit (PDU) with emergency power off (EPO) functionality, designed for three-phase power distribution in structured data center and enterprise rack environments. Rated at 24 amps with an L21-30 input connection, this unit distributes power across multiple outlets from a single three-phase feed. Licensed electricians and data center facilities technicians install and commission this type of PDU as part of a managed power infrastructure. The EPO feature allows a single-point shutdown of all connected loads during emergencies or planned maintenance windows.

This PDU is suited for 2U rack enclosures in enterprise server rooms, network closets, and data center deployments where three-phase power is available at the rack level. The L21-30 twist-lock inlet accepts a standard three-phase 30-amp circuit, making it compatible with typical data center PDU branch circuits. The EPO circuit integration supports facility-level emergency shutdown systems, a common requirement in larger enterprise and colocation installations.

Key Features

• Emergency power off (EPO) function enables single-point shutdown of all connected loads
• 2U rackmount form factor fits standard 19-inch equipment racks
• NEMA L21-30 three-phase twist-lock input rated at 24 amps
• Three-phase power distribution suited for high-density rack deployments
• Enterprise-grade PDU category supporting structured power management

Compatibility

Designed as an OEM-style replacement or direct-install PDU for enterprise rack systems requiring a 2U three-phase power distribution unit with EPO capability and an L21-30 input connection.

Installation Notes

Installation should be performed by a licensed electrician familiar with three-phase branch circuit wiring and NEC requirements for data center power distribution. De-energize the upstream three-phase circuit breaker before connecting or disconnecting the L21-30 inlet. The EPO control wiring must be run and terminated in accordance with facility emergency shutdown system requirements and applicable electrical codes. Do not exceed the rated 24-amp continuous load on the input circuit.
