1SAX121001R1104
ABB EF19-6.3 is a precision electronic overload relay engineered for superior motor protection. With an adjustable setting range of 1.90 to 6.30 Amperes, it provides high-accuracy protection against overloads, phase failures, and phase imbalances. Utilizing electronic sensing technology, the EF19-6.3 ensures reliable tripping and offers selectable trip classes to accommodate various motor starting conditions.

Key Technical Features:

Precision Sensing: Offers a 3.3:1 setting range (1.9-6.3A), allowing one relay to cover multiple motor sizes with electronic accuracy.

Selectable Trip Classes: Easily adjustable between 10E, 20E, and 30E to protect motors during normal or heavy starting sequences.

Temperature Independence: Electronic measurement remains stable and accurate regardless of the heat inside the electrical cabinet.

Phase Loss Sensitivity: Rapidly detects phase loss or imbalance to prevent motor winding damage.

Direct Mounting: Designed for quick and easy direct connection to AF09, AF12, AF16, AF26, AF30, and AF38 contactors.
