Product Overview

The LayerZero eRDP 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, while maintaining selective trip coordination. It can accommodate up to 168 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 ePanel HD2 is 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 ePanel HD2 is a safe and reliable piece of equipment that is designed to protect operators and equipment.

Reliability Features
