Apc PDM3520L2120-380 It Power Distribution Module

Product Description

The APC PDM3520L2120-380 is a power distribution module designed for IT infrastructure environments, including data centers, server rooms, and network closets. It takes high-capacity upstream power and distributes it to downstream equipment in a structured, manageable way. Electrical contractors and data center technicians are the primary installers. The MPN encodes key electrical parameters: 35-amp total capacity, 20-amp branch circuits, and an L21-20 locking receptacle configuration at 208/240 volts three-phase, making it suited for high-density rack power distribution.

This power distribution module is used in commercial and enterprise IT settings where upstream three-phase power must be broken into individual branch circuits for servers, storage arrays, networking gear, or other rack-mounted equipment. It is typically installed in standard equipment racks or cabinets as part of a structured power chain from a static transfer switch or UPS output. The unit is intended for professional installation in facilities with three-phase electrical service.

Key Features

• Distributes three-phase power to multiple branch circuits within a rack or cabinet
• L21-20 locking receptacle configuration for secure, high-current connections
• 35-amp total load capacity supports high-density IT equipment
• 20-amp individual branch circuits provide balanced load distribution
• Designed for integration with APC UPS and power conditioning equipment

Compatibility

Designed as an OEM-style power distribution module for use in professional IT rack and cabinet installations requiring three-phase power distribution.

Installation Notes

Installation should be performed by a licensed electrician familiar with three-phase power distribution and applicable NEC requirements. De-energize the upstream power source and verify zero voltage before making any connections. Confirm that upstream circuit capacity, breaker ratings, and wiring gauge are appropriate for the module load before commissioning. Do not exceed the rated ampacity of the unit or individual branch circuits.
