Description

The Square D B4.65 is a melting alloy type thermal unit designed for use in overload relays, providing reliable motor protection against overload conditions in industrial and commercial applications. This thermal unit is compatible with Square D Class 9065 overload relays and is typically used in motor starters for NEMA sizes 0 and 1. It features a bimetallic element that heats up and trips the relay when current exceeds safe levels, preventing motor damage from prolonged overloads. Key benefits include easy installation, precise calibration for specific full load amp (FLA) ranges, and durability in harsh environments. Compared to electronic overload relays, it offers simplicity and cost-effectiveness without needing external power, though it may lack advanced diagnostics. Drawbacks include fixed trip characteristics and the need for manual reset. Ideal for pumps, conveyors, and HVAC systems, this unit ensures compliance with UL and CSA standards. Condition: Brand new in original packaging, as evidenced by unopened box and pristine component appearance in images. No visible wear, serial numbers not discernible from photos. No parent/child assets attached.
