Advance Controls CK09-RHU-10 is a three-pole magnetic contactor paired with a RHU-10/1 thermal overload relay for motor control in three‑phase circuits. The RHU-10/1 overload relay is rated for 460 V and provides an adjustable trip setting from 17.5 to 21.5 A, enabling tailored motor protection within typical industrial load ranges. This combination is used to switch motor power while protecting the motor from overload, and it is commonly installed with CK09‑series contactors in automation and control panels to deliver integrated switching and protection.
