Product Details
Eaton Overload Relay, Direct Contactor Mounting, 440V AC Isolation - ZB Series - 278438 ZB12-4
Use this overload relay from Eaton to protect your motor from overcurrent damage in industrial applications. It has auxiliary contacts that disconnect the unit when there’s an overload, avoiding harm to users or equipment. You can then simply reset the unit when normal conditions are restored. As it offers electrical isolation up to 440V AC as per EN 61140, you can be assured of protection in the event of a significant surge. The relay's continuous temperature compensation means it self-adjusts to keep your device thermally stable. This helps to prevent the harmful effects of excessive heat on internal components.
