It lets you mount the reset actuator on a cabinet door or remote panel while the overload relay stays inside the enclosure — no need to reach into a live panel to reset a tripped relay. ## Compatibility and lifecycle status This cable release fits the 3RU11, 3RB20, and 3RB21 overload relays in sizes S00, S0, S2, and S3. The description explicitly marks it as a phased-out product. The preferred successors are the 3RU2900-1C or the 3RB3980-0C.
