Aci 104139 Indicating Light 24V Green Round Lens

Product Description

The ACI 104139 is a 24-volt green lens indicating light designed for status and fault indication in HVAC, electrical, and building automation control panels. It features a round lens profile and a blade connector termination, making it a straightforward drop-in for panel builders and service technicians replacing failed indicator lamps. The green lens provides a clear visual signal for system-on or normal-operation status. At 0.1 pounds, the unit is compact and lightweight, suited for tight panel layouts where space is limited.

This indicating light is commonly used in residential and light commercial HVAC control panels, electrical enclosures, and automation equipment where low-voltage pilot light indication is required. It is typically installed during panel assembly or as a field replacement when an existing indicator light fails or is damaged. The 24-volt rating aligns with standard low-voltage control circuit voltages common in HVAC equipment.

Key Features

• 24-volt operating voltage matches standard low-voltage HVAC control circuits
• Green lens provides clear normal-operation or system-on status indication
• Round lens shape for conventional panel cutout installations
• Blade connector termination for fast, tool-free wiring connections
• Lightweight at 0.1 pounds for use in space-constrained enclosures

Compatibility

Designed as an OEM-style replacement indicating light for 24-volt control panels and electrical enclosures requiring a round-lens, blade-connector pilot light.

Installation Notes

Installation is typically performed by a licensed electrician or HVAC technician. De-energize the control panel and verify zero voltage at the circuit before handling any wiring. Blade connector terminations should be fully seated to ensure a secure electrical connection. Follow applicable NEC guidelines for low-voltage control wiring within enclosures.
