166G6B

Overview

The Hammond Manufacturing 166G6B is a low voltage industrial power transformer designed for chassis mounting. It features a single primary winding rated at 115 VAC and a single secondary winding providing 6.3 VAC center-tapped output with a current rating of 600 mA. The unit has a power capacity of 3.78 VA and operates at frequencies of 50 Hz or 60 Hz. Physical dimensions are 2.38 inches in length, 1.38 inches in width, and 1.38 inches in height. It utilizes wire leads for termination and functions within an operating temperature range of 0°C to +130°C.

Feature Summary

• Chassis mount construction with wire lead terminations
• Single primary and single secondary winding configuration
• Low voltage operation suitable for industrial control applications

Applications

• Industrial control panels
• Equipment requiring isolated low voltage power supplies
• General purpose AC to AC power conversion in machinery

Procurement Notes

Verify the specific primary voltage requirement (115V vs 117V) against the source equipment specifications before procurement. Confirm that the chassis mounting style and wire lead termination method are compatible with the intended installation environment. Ensure the 3.78 VA power rating meets the load demands of the connected circuitry to prevent overheating or failure during operation.

Selection Notes

Select this component when a compact, chassis-mountable transformer is required for low voltage applications. The 166G6B is appropriate for systems needing a 6.3V center-tapped secondary from a standard 115V/117V primary source. Consider the physical dimensions and weight constraints of the enclosure. Verify that the operating temperature range of 0°C to +130°C aligns with the environmental conditions of the deployment site.

Part Context

This component belongs to the Hammond Manufacturing 166 series of industrial power transformers. The series is characterized by laminated core construction and robust chassis mounting designs intended for heavy-duty industrial environments. These transformers are engineered to provide reliable isolation and voltage transformation for control circuits and instrumentation within larger electrical systems.

Replacement Considerations

Direct substitutes must match the 3.78 VA rating, 115V primary, and 6.3V CT secondary specifications. Verify that any replacement maintains the same chassis mounting footprint and wire lead configuration to ensure mechanical compatibility without requiring enclosure modifications.
