ABB 1SAX121001R1103 | EF19-2.7 Electronic Overload Relay, 0.80-2.7A

ABB EF19-2.7 electronic overload relay - 0.80 to 2.7 A

ABB 1SAX121001R1103 is the ABB EF19-2.7 EF electronic overload relay for accurate motor overload protection in low-voltage motor control panels. The ABB part number 1SAX121001R1103 covers a current setting range of 0.80 to 2.7 A, making it a precise choice for contactor feeders, pump panels, fan starters, compressor panels, conveyor controls, HVAC motor circuits and factory maintenance spare parts.

The ABB EF series is often searched as an ABB thermal overload relay because it performs the same motor-protection role as a thermal overload while using electronic sensing for a wider setting range, high accuracy and stable protection behavior. For engineers replacing or specifying 1SAX121001R1103, the key identifiers are ABB EF19-2.7, SKU 1SAX121001R1103 and current range 0.80 to 2.7 A.

The EF19-2.7 is a self-supplied electronic overload relay, which means no extra external supply is needed. It offers reliable and fast protection for motors in the event of overload or phase failure. Easy to use like a thermal overload relay and compatible with standard motor applications, the electronic overload relay is convincing, above all, due to its wide setting range, high accuracy, high operational temperature range and the possibility to select a trip class (10E, 20E, 30E). Further features are the temperature compensation, trip contact (NC), signal contact (NO), automatic- or manual reset selectable, trip-free mechanism, STOP- and Test function and a trip indication. The overload relays are connected directly to the contactors. Single mounting kits are available as accessory. The EF19 and EF45 have ATEX and IECEx certification
