Reliamod RMM3BB 1600A 3PH 4W RELT KIT (Unused)

1600A (1600 Amperes): The current rating of the electrical equipment the kit is designed for. 3PH (Three-Phase): Refers to a three-phase electrical power system, commonly used in industrial and commercial applications. 4W (Four-Wire): Indicates that the system includes three phase wires and one neutral wire, which is typical for a wye configuration (e.g., 480Y/277V or 208Y/120V). RELT (Reduced Energy Let-Through): This is a safety feature that, when activated temporarily (e.g., during maintenance work), lowers the trip unit's instantaneous overcurrent pickup threshold. The goal is to make the breaker trip faster in the event of an arc fault, thereby limiting the arc flash energy and improving personnel safety while working near energized equipment. KIT (Kit): Signifies that it is an accessory or a set of parts designed to be added to existing compatible equipment, rather than a complete, standalone product.
