ABB EF19-18.9 Electronic Overload Relay | 5.70A to 18.90A Range

1SAX121001R1105
ABB EF19-18.9 is a self-supplied, high-accuracy electronic overload relay designed for the comprehensive protection of motors ranging from 5.70 to 18.90 Amperes. By utilizing advanced electronic sensing, it provides superior protection against overloads, phase failures, and phase imbalances. It is the ideal energy-efficient upgrade for control panels using ABB AF contactors.

Key Technical Features:

Broad Setting Range: A 3.3:1 adjustment ratio (5.7-18.9A) allows one unit to cover a wide variety of motor horsepowers.

Flexible Trip Class Selection: User-selectable trip classes (10E, 20E, 30E) ensure the relay can handle standard or heavy-duty motor starts without nuisance tripping.

Ambient Temperature Independence: Unlike thermal relays, the EF19-18.9 maintains its accuracy even in hot industrial cabinets or fluctuating environments.

Integrated Safety: Features a built-in trip indicator and a test/stop button for rapid troubleshooting and maintenance.

Direct Contactor Mount: Fits perfectly onto the load side of AF09, AF12, AF16, AF26, AF30, and AF38 contactors.
