Eaton 9-3256-3 Ac Type Overload Relay 2 to 4 Pole

Product Description

The EATON 9-3256-3 is an AC-type overload relay designed to protect motors and electrical equipment from damage caused by sustained overcurrent conditions. Rated for 2 to 4 pole configurations, this relay monitors current draw and trips the circuit when unsafe levels are detected, preventing motor burnout and equipment failure. It is a standard component in motor control centers, combination starters, and standalone starter assemblies used in commercial and industrial electrical systems. Licensed electricians and HVAC controls technicians install this device as part of motor protection schemes across a wide range of load types.

This overload relay is suited for use in motor starter assemblies handling AC-driven loads in commercial buildings, light industrial facilities, and mechanical rooms. Common applications include fan motors, pump motors, compressor controls, and other multi-pole motor circuits where reliable overcurrent protection is required. The 2 to 4 pole design supports flexible wiring configurations to match the pole count of the controlled motor or load.

Key Features

• AC-type overload relay with 2 to 4 pole configuration support
• Provides overcurrent protection to prevent motor burnout
• Compact form factor fits standard motor starter and control panel assemblies
• Designed for reliable operation in commercial and industrial motor control applications

Compatibility

Designed as an OEM-style replacement or upgrade overload relay for AC motor starter assemblies requiring 2 to 4 pole overcurrent protection.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC guidelines. De-energize and lockout/tagout the motor control panel before removing or installing any overload relay. Verify pole count and current rating match the motor nameplate and starter assembly before energizing. Confirm all terminal connections are secure and the relay trips freely before returning the circuit to service.
