Eaton Overload Relay, Direct Contactor Mounting Style, IP20 Rating - ZB Series - 278439 ZB12-6
Protect your electric motor from excessive current supply by using this overload relay from Eaton. You can adjust the current range between 4A and 6A, making it a versatile choice. It's finger and back-of-hand proof, so is safe to set up manually without the risk of electric shock. Built-in mechanical shock resistance helps to prevent false tripping in demanding conditions where heavy vibration is likely. For easy mounting, this unit attaches directly to the contactor. Overload relays like this one are commonly found in factory automation and industrial control applications.
Features & Benefits
• ATEX certified for safe use in hazardous locations
• Complies with IEC/EN 60947 standards for use in low-voltage electrical systems
• Manual and automatic reset for versatile operation
• Broad operating temperature range of -5°C to +55°C means it performs effectively in harsh industrial environments
What's the difference between an overload relay and a motor protection circuit breaker?
An overload relay typically protects the motor from current faults alone, while a motor protection circuit breaker protects the motor from current overload as well as short circuits.
