According to the point 4.4.1 of the test report no. 2221/0017, the measured circuit breaker operating time is 2.6 ms

The PGU can either be assembled with following alternatives of the circuit breaker:

- Alternative 1: Power Relay CHAR-112A200 with: - Declared operate time given by the supplier: 35 ms as maximum. - Declared release time given by the supplier: 30 ms as maximum.

- Alternative 2: Power Relay 511ZP-1AD-F-C M06 with:

- Declared operate time given by the supplier: 50 ms as maximum. - Declared release time given by the supplier: 30 ms as maximum.
