1SDA057000R1 ABB E6H 5000 PR121/P-LI In=5000A 4p W MP

The 1SDA057000R1 ABB E6H 5000 PR121/P-LI is a moving part designed for use with ABB’s SACE Emax E6H circuit breakers. It’s tailored for high-capacity power distribution systems with demanding current ratings, especially suited for industrial and large commercial environments requiring reliable overcurrent protection. Here’s a deeper look into its features and functionality:

Key Specifications and Features

1. Rated Current (In):
   • 5000A: This component supports a substantial current rating, making it ideal for heavy-duty applications that demand high current-carrying capacity.
2. Poles:
   • Four-Pole (4P): The four-pole configuration provides protection across three phases with an additional neutral pole. This setup enhances safety in power systems by ensuring full-phase fault protection, including neutral monitoring.
3. Overcurrent Protection:
   • PR121/P-LI Release: Equipped with ABB’s PR121/P-LI overcurrent release, which offers customizable long-time (L) and instantaneous (I) protection. This ensures that the circuit breaker can handle overloads and short-circuits, crucial for maintaining the stability and safety of high-power systems.
   • Settings: The PR121/P-LI allows users to set trip characteristics to match specific system requirements, making it adaptable to a variety of operational conditions.
4. Auxiliary Contacts:
   • 4 Auxiliary Contacts: These contacts provide additional monitoring and control capabilities, allowing integration with control panels or remote systems. This is useful for applications where remote signaling and indication of breaker status are needed.
5. Breaker Position Indication:
   • Open/Closed Position Indication: This feature provides clear visibility of whether the breaker is in the open or closed position. It enhances operational safety, allowing personnel to confirm breaker status before conducting maintenance or system inspections.

This moving part for the E6H circuit breaker emphasizes high performance, reliability, and flexibility in protecting critical power distribution setups, aligning with ABB’s standards for industrial-grade safety and efficiency.
