ESD-201, ESD-202, Energy Storage Device

The ESD line of energy storage devices is a cost-effective solution to provide reliable power for circuit breaker tripping when station batteries are not present. The ESD converts AC input voltage into DC voltage and stores sufficient energy for up to 72 hours after AC is removed to trip the circuit breaker in the event of a system fault.


  • Provides reliable circuit breaker tripping energy in a cost-effective package.
  • Extremely rugged, potted design is well suited for harsh environments, ensuring reliable operation.
  • User-friendly LED indicator provides confidence that sufficient energy is available for breaker operation.
  • The ESD-201's ability to accept multiple voltage inputs makes it easy to adapt into a variety of applications.
