Allen-Bradley / Rockwell Automation NEMA Overload Relay Heater Element WL72

The WL72 NEMA Overload Relay Heater Element from Allen-Bradley / Rockwell Automation is classified as a Class 30 protection device, suitable for applications requiring extended overload protection. It is designed to trip in 30 seconds or less when carrying a current equal to 600 percent of its rated capacity. This heater element is part of the Type WL series, which is recommended for motors driving high inertia loads, where additional acceleration time is necessary. The WL72 heater element does not comply with EU ROHS material restrictions. It is essential to select the appropriate heater element based on the motor's full load amperes and ambient temperature conditions, as outlined in the heater element selection procedure. This product is intended for use in conjunction with Allen-Bradley overload relays to provide reliable motor protection in various industrial applications.
