    Selective Coordination Solutions

    Combining innovative engineering with validated test results.

Challenges

Certain electrical power system designs need to ensure the selection and setting of protective devices cause the smallest possible portion of the system to be de-energized due to an abnormal condition.

  • Solutions

    In a selectively coordinated system, only the circuit breaker that directly supplies the overloaded/faulted part of the system will trip, limiting the service interruption to only the circuit experiencing the problem and not shutting down the larger portion of the power system.

  • Value Proposition

    Square D solutions provide peace of mind when power availability is critical by delivering high levels of selective coordination in flexible designs that are easily configured for a variety of applications, and are tested to be selectively coordinated.

  • Differentiation

    Use the Square D Mission Critical circuit breakers to achieve best-in-class coordination levels, allowing total selective coordination down to 0.01 with continuity of service.

Applications

Selective coordination is mandatory per the NEC for the circuit paths of vital loads on specific systems, including:
• Elevators, Dumbwaiters, Escalators, Moving Walks, Platform Lifts, and Stairway Chairlifts
• Emergency Systems:
• Legally Required Standby Systems:
• Critical Operations Power Systems (COPS):

Benefits

    Wide range of ampacities and configurations to meet the unique needs of specific power systems
  • Business people working in video conference
    Tested and certified to be selectively coordinated up to 30kA when using PowerPact™ Mission Critical main breakers.
  • Man working in data center, data center management, data center operations.
    Conducting a comprehensive short-circuit current study and an overcurrent coordination study of the electrical power system is the only true method of achieving selective coordination and equipment protection.
