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.
Features & Benefits
• Manual and automatic reset options help you avoid downtime
• Bimetallic mechanism gives trip response between 2 and 10s
• Modular relay design compatible with the DILM contactor range
• Safe for use with potentially explosive components
• Operating temperature range of -25°C to +55°C, so suitable for use in extreme environments
How durable is this overload relay?
This relay resists corrosion, thermal overload and UV radiation according to IEC/EN 61439, so it’s a durable product.
