Product Overview

The LayerZero ePanel FSR (Left) is a web-enabled remote power panel (eRPP) with 42-circuit SafePanel® distribution. It is a SIMO configuration (single input, multiple outputs), meaning that it has a single input power source and multiple output circuits. The eRPP-FSR (Left) is ideal for applications that require high-reliability power distribution in a wall-mounted, space-saving design.

The core functionality of the LayerZero ePanel FSR (Left) is to distribute power to a large number of circuits, while maintaining selective trip coordination. It can accommodate up to 84 finger-safe circuits. This makes it ideal for applications with high power requirements, such as data centers and large industrial facilities.

The ePanel FSR (Left) 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 eRPP-FSR (Left) is a great option.

Safety Features

Safety Features

The LayerZero ePanel FSR (Left) 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 SL-1 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 eRPP-FSR (Left) is a safe and reliable piece of equipment that is designed to protect operators and equipment.
