Eaton Overload Relay, 440V AC Isolation, IP20 Rated - ZB Series - 278440 ZB12-10
Protect people and equipment from the dangers of electrical faults with this overload relay from Eaton. It reliably disconnects your circuit in case of a thermal overload or overcurrent to minimise the risk of damaging your connected load-drawing equipment. The relay resets automatically or can be reset manually using a simple push button, so you can rely on it to minimise downtime. As it has an operating temperature range of -25°C to +55°C, this is a suitable option for use in harsh environments. You'll commonly find it used in motor control centres for motor starting applications.
Features & Benefits
• Modular unit for wide compatibility with DILM contactor range
• Bimetallic tripping means you get a response time between 2 and 10s
• Safe for use with potentially explosive applications
• Continuous compensation helps keep the relays temperature constant
• Bimetallic tripping means you get a response time between 2 and 10s
• Safe for use with potentially explosive applications
• Continuous compensation helps keep the relays temperature constant
Does this relay offer electrical isolation?
Yes, this overload relay meets the IEC's EN 61140 standard and is safely isolated up to 440V AC. This means you and your equipment will be protected in the event of a significant surge.
