ABB Overload Relay, Screw Terminals, 2 Auxiliary Contacts - EF19 Series - 1SAX121001R1104 EF19-6.3 Keen to steer your motor-driven kit clear of electrical faults? Put this ABB overload relay into the driving seat. As the unit trips for overload and phase failure, it cuts the risk of machine damage caused by everyday power issues. An adjustable current setting between 1.9 and 6.3A means it adapts to its supply to deliver flexible protection. Connecting the device to a contactor (764-8983) is easy, thanks to its snappy plug-in fitting. For handy automated control, two auxiliary contacts are on hand to signal linked devices when it trips. Features & Benefits • Screw conductor terminals for a tight hold against movement
• Automatic and manual reset modes for close restart control
• Trip-free mechanism breaks the circuit without moving the actuator, minimising disruption from tampering
• Test button simulates fault signals to quickly check circuit safety
• Screw dial controls to easily adjust current setting and reset mode Applications • Motor starters
• Industrial automation
• Bottling plants Where does this overload relay draw power from? This device draws power from its contactor, cutting the need to wire up a separate power supply.
