Panel Indicators & Pilot Lights – C461-LRG28H-NGO Application Field and Working Principle

Panel indicators, pilot lights, and beacons are devices that produce an illuminated signal. The most common and basic unit of indication is the illuminated pilot light. Pilot lights are small devices that fit within a panel indicator switch gear and are designed to identify a fault or confirm the state of a circuit, or provide a visual indication of the presence of an electrical current to Isolating Equipment or Enclosure. The C461-LRG28H-NGO is a panel indicator and pilot light manufactured by ABB, Inc. that is used to monitor and control the flow of electricalcurrent in high voltage systems.

Applications

The C461-LRG28H-NGO is a three-color, latch-lamp device that is designed to absorb electrical impacts in applications up to 315V and increase the safety of personnel working near high voltage installations. Possible applications for the C461-LRG28H-NGO include heavy equipment, industrial control panels, switchgears, power distribution boards, ships and industrial machinery.

Working Principle

Panel indicators, pilot lights, and beacons all work using an electric current. The current passes through the device’s bulbs or LEDs activating the device and allowing it to emit an illuminated signal. The C461-LRG28H-NGO panel indicator and pilot light is designed to identify a fault or determine the status of a circuit, and protect personnel working in the vicinity of high voltage installations. The device consists of three independent elements that are triggered independently by either 120V AC power or a direct current up to 315V. The individual elements can also be combined to create a two-color or four-color indication.

The C461-LRG28H-NGO is designed to be used in hazardous environments such as substations, power distribution boards, and high voltage equipment rooms. It is capable of withstanding impacts up to 315V AC or DC and offers a range of options for signal indication. The device is built with the latest safety certification standard to protect personnel and the environment in which it is installed.

Installation

The C461-LRG28H-NGO panel indicator and pilot light is easy to install. A bracket is included with the device and it can be mounted to a flat surface. The panel indicator needs to be connected to a power supply and must be wired to the circuits for which the indication is desired. The safety of personnel working in the vicinity of high voltage installations can be ensured by connecting the power supply to a ground fault protection device.

Maintenance and Support

The C461-LRG28H-NGO panel indicator and pilot light is designed to last a long time without requiring much maintenance. The device should never require service, however, it is important to check the integrity of all components at regular intervals to ensure that the functioning of the device is not hindered. ABB, Inc. offers full technical support to customers and can help investigate technical queries related to the product.
