7XV7500-1CA00 Siemens 7XV75 Test Switch for Feeder Protection
The Siemens 7XV7500-1CA00 belongs to Siemens’ 7XV75 test switch family, listed among the protection accessories in the SIPROTEC catalogue. Siemens describes it as a test switch without open star point for feeder protection, with 16 banana plugs, in a 1/6 case 7XP20 for panel flush mounting. It gives protection engineers a dedicated, panel-mounted interface for connecting a secondary injection test set to a protection relay, without rewiring the panel.
What the 7XV75 Test Switch Does
According to Siemens, the 7XV75 test switch is used to test protection devices with secondary injection test sets, for example the 7VP15 (Omicron CMC 56). It covers the device’s current transformer (CT) circuits and command contacts. Switches on the front of the unit move the protection device between operation and test, so that current and voltage can be fed in from the injection test set.

Why Specify the 7XV7500-1CA00
- Purpose-built Siemens test switch for feeder protection schemes
- Front-panel switching between operation and test
- 16 banana plug test connections for direct connection of test leads
- Standard Siemens 7XP20 1/6 case for panel flush mounting
- Matches the 7XV75 range, so test switches can be standardised across a substation or panel line-up
Ordering the Right 7XV75 Version
The 7XV75 versions differ in star point configuration, additional contacts and test plug type. When ordering a replacement, always quote the full order number shown on the existing unit (e.g. 7XV7500-1CA00 rather than 7XV7500-0CA00 or 7XV7501-1CA00).
