Trip relay
7PG11 - 7PG18
SIEMENS Smart Grid
The Alpha range comprises electro-mechanical relays for a range of auxiliary functions. Various combinations of coils, contacts, operation indicator flags can be specified. Options are also available for operate and reset modes.
- 7PG11 AR relays - general auxiliary functions - repeats, indications, scheme logic FR relays
- 7PG13 MR relays - AC current measuring relay with fixed or variable setting
- 7PG15 TR relays - High speed multi contact tripping relays, available in both high and low burden models. Variants up to 11 contacts. <10ms operation.
- 7PG17 XR relays - Interposing relay for control applications, supply supervision, trip circuit supervision, ferroresonance alarm
- 7PG18 TR-A relays - High speed multi contact tripping relays, high burden models - 20 contacts only. <12.5ms operation.
