Product Overview

The LayerZero eRDP-FS (eRDP-1) is a web-enabled remote distribution panel (eRDP) with subfeed distribution. It is a MIMO configuration (multiple inputs, multiple outputs), meaning that it can have multiple input power sources and multiple output circuits. The eRDP is ideal for applications that require high-reliability power distribution in a space-saving design.

The core functionality of the LayerZero eRDP is to distribute power to a large number of circuits. It can accommodate subfeed circuit breakers, including both finger-safe and non-finger-safe breakers. This makes it ideal for applications with high power requirements, such as data centers and large industrial facilities.

The eRDP also features a number of safety features, including SafePanel® distribution, dead front doors, no exposed live parts (NELP) and polycarbonate windows. These features help to protect users and equipment from electrical hazards.

If you are looking for a high-reliability, safe, and versatile power distribution solution, the LayerZero eRDP is a great option.

Safety Features

The LayerZero eRDP-FSis designed for maximum operator safety. It uses a sectionalized design, which means that the power quality monitoring is housed in a separate section from the circuit breakers and customer cable connections. This compartmentalized design allows the equipment to be safely operated and serviced.

In normal operation, the inner dead-front doors of the HD2 remain closed.

A polycarbonate window in the door allows operators to safely view the circuit breaker positions with the dead front door closed. INSIGHT IR® cameras (optional) or an IR Port (standard) provides the ability to monitor the temperatures of critical connections with the doors safely closed.

The LayerZero Power Systems eRDP-FSis a safe and reliable piece of equipment that is designed to protect operators and equipment.
