For control rooms & critical control centers · Siemens SENTRON ECPD

No downtime. No outage risk. No compromises.

Semiconductor-based protection for 24/7 operation — with cyclic self-tests and guaranteed selectivity at the function level.

Critical operations

Three issues that cost you availability.

Maintenance

No window for mandatory testing

DGUV V3 inspections require downtime — which 24/7 operations don't have.

Cascade

Failures propagate

Conventional protective devices are too slow — one short circuit knocks out the upstream section.

Legacy

Modernizing during operation

New protection requirements without rebuilding the control cabinet — barely feasible with conventional technology.

Where the ECPD comes in

Everyone protects software and systems — no one protects the upstream circuit.

Dispatch system redundant, servers mirrored, UPS in the basement — yet the circuit feeding all of it hangs on an off-the-shelf breaker. That is where the risk lives, and exactly where the ECPD comes in.

With the ECPD

Protection that doesn't interrupt operations.

Three capabilities that qualify the ECPD for 24/7 environments.

01 · Self-test

Cyclic self-tests during live operation

Functional testing runs automatically, without interrupting the load. DGUV V3 intervals can be extended via a recognized certificate — maintenance windows become avoidable.

Self-test with report · test interval × 8

02 · Selectivity

Faults stay on their circuit

Semiconductor technology disconnects in under 50 microseconds. A short circuit at an operator workstation, a server, or the UPS interface doesn't cascade to the upstream level.

~50 µs switching time · guaranteed selectivity

03 · Retrofit

Retrofit without rebuilding the control cabinet

One ECPD on 2 MW replaces eight conventional devices spanning 16 MW. New protection functions fit into the existing cabinet — no parallel control cabinet, no extended downtime.

16 MW → 2 MW · no new distribution board

Trust

Siemens quality, semiconductor-based.

The ECPD is part of the SENTRON line — the same family that has been installed in low-voltage distribution boards for decades.

01

Compliance & certification

CE declaration of conformity. Meets the key protection objectives of DIN VDE 0100-4xx. The product standard IEC 63464-1 (SC-RCBOs) is in preparation — publication planned for 2028.

02

Proven component family

SENTRON is Siemens' low-voltage product line with decades of market presence. The ECPD extends this line with semiconductor-based functions.

03

Cybersecurity by Design

Encrypted wireless communication (ZigBee, BLE). Configuration protection with local device authentication. Signed firmware only. Ships secure by default.

Webinar: ECPD & Workplace Protection

Together with Siemens, we show how to protect critical workstations at final-circuit level — including a live ECPD demo and open Q&A.

  • The protection gap between distribution board and workstation
  • Live demo: parameterization & fault response in real time
  • Q&A with the Siemens and Circuit Electronics experts

Access details will be emailed ahead of the session. Registration data is shared with co-host Siemens to run the webinar. Privacy
