The W67 thermal overload relay heater element by Allen Bradley is essential for providing protection to electric motors. It is designed to work with efficient full load amperes (FLA), accommodating Size 0 through Size 3 at ratings between 32.0 A and 36.5 A.

This unit operates at a maximum rated voltage of 600 V AC, ensuring compatibility across a range of systems. It adheres to the standards outlined in NEMA ICS 2, Part 4, confirming its reliability in various industrial applications. The overload relay utilizes a eutectic alloy to provide effective thermal protection.

With a trip class of 20, the W67 has a defined trip time at 600% of the rated current, which is noted to be ≤ 20 seconds for Class 20 applications. Other trip classifications, such as Classes 10 and 30, are not applicable for Type J and Type WL respectively. This specification is critical for integration in applications requiring precise thermal overload management. Overall, the W67 is tailored for use in robust environments where effective motor protection is necessary.
