Siemens 3SB3 244-6AA40 Pilot Light

Siemens 3SB3 244-6AA40 Pilot Light is a green, plastic-encased indicator in the Siemens 3SB3 signaling family, built for 24 VAC or 24 VDC operation to provide a visible status signal on control panels and equipment. The 244-6AA40 variant identifies green illumination and a plastic housing, making it suitable for use in standard industrial control circuits that require a durable, low-profile indicator light. As part of the 3SB3 line, it is designed to be paired with compatible Siemens pushbuttons and indicator modules to form a compact signaling unit for panel installations. The unit is intended for panel-mount applications where a clear green status indication is needed to convey machine readiness, run state, or a similar condition in automation environments. This pilot light relies on a 24-volt control signal and is compatible with both AC and DC 24-volt supplies, a common requirement in modern industrial control systems. The green color provides quick visual recognition for operators and electricians, minimizing confusion during start-up and maintenance.
