The 777 unit is a fully-programmable, electronic overload relay designed to protect any motor drawing 2-800 full load A (external CTs are required above 90 A). The 777 (family of products) is used for 3-phase, 200-480 V ac applications, with several specialized units for other voltage ranges and unique applications. Common applications include conveyor systems, HVAC equipment, saws and grinders, fan motors, and almost any pumping application. Some unique applications include use with a Subtrol* equipped Franklin submersible motor to detect high motor temperatures and applications where a fast linear trip is required.

All of the overload relays provide unsurpassed protection by combining overload, voltage, phase loss and reversal, voltage and current unbalance, power monitoring, and underload based on current - all in one package. 単独アプリケーション用に、ユニットには 3 桁の LED ディスプレイが組み込まれており、プログラミング、リアルタイムの動作情報の提供、故障状態のトラブルシューティングを支援する診断コードの表示に使用されます。 The units also feature a communications network port that can be used with communication modules listed in the 777 accessories section to form a Modbus, DeviceNet*, Profibus, or Ethernet network. PC、PLC または SCADA システムから最大 99 ユニットをリモートで監視・制御でき、オプションの Solutions ソフトウェアを使って PC からデータロギングが可能です。この機能により、アーク放電の安全性に関する新しい要件を満たすためのシンプルで費用対効果の高い方法を提供します。
