Electronic Overload Relay 4-20A 45 mm Frame Separate Mount NEMA Eaton C440· A020SAX

SKU: EAT-C440A1A020SAX

Electronic overload relay for NEMA motor control applications with an adjustable 4-20A overload range, 45 mm frame, and separate-mount design. Selectable trip class 10A, 10, 20, or 30 helps match motor starting characteristics in industrial control panels.

What this product is for

This electronic overload relay is used to protect AC motors in NEMA starter and motor control applications. It monitors motor current and helps trip on overload conditions before motor damage occurs.

Use for

Use for industrial motor starters, replacement overload protection, OEM panels, and machinery where a 4-20A adjustable overload range fits the motor full-load current. The separate-mount format is suited to panel layouts that do not require an assembled starter-mounted overload.

Avoid for

Avoid for motors outside the 4-20A setting range or applications requiring a different frame size, mounting style, or advanced networked protection package not included with the standard version.

Best for

Best for electricians, maintenance teams, and panel builders needing compact electronic motor overload protection for Eaton Freedom NEMA systems. Selectable trip class settings are useful where motor starting time varies by load.

Installed in

Typically installed in industrial control panels, MCC-related assemblies, machinery skids, pump panels, fan controls, and manufacturing equipment. Product size is approximately 4.32 in x 1.8 in x 3.8 in (110 x 46 x 97 mm).

Why this product exists

This relay provides more precise motor protection than traditional thermal overload styles by electronically monitoring current in each phase. It is intended to help reduce nuisance issues while still protecting motors in demanding operating conditions.

Compared with similar products

Compared with fixed-trip or narrower-range overloads, this model offers an adjustable 4-20A range and selectable trip class 10A, 10, 20, or 30. Compared with assembled overload options, this is a separate-mount unit for applications where panel layout flexibility matters.

Typical buying guidance: match the overload setting to the motor nameplate full-load current and verify starter compatibility before ordering. Actual protection performance depends on motor characteristics, ambient conditions, installation, and local electrical code.
