RGM series trip relays (2 to 8 changeover contacts) are very reliable products offering optimal performance, suitable for applications in particularly difficult and unstable environments, such as:
- High voltage electricity distribution stations and medium voltage substations
Knurled contacts to provide lower ohmic resistance thanks to the multiple electrical connection points:
- Extended electrical life of the component
- Optimal performance for highly inductive DC loads and for very low loads, as in the case of interface signals.
High breaking capacity to control very heavy DC loads, also with a high switching frequency.
Nominal voltage available from 12 to 220VDC / 440VAC, with several operating ranges.
Ability to adapt products to meet specific application requirements.
Typical areas of application are among the most demanding, such as:
- Power stations
- Electrical transformer stations
- Stationary equipment for railways
- Industries using continuous production processes (chemicals and petrochemicals, rolling mills, cement works , etc.)
The RGR is suitable for:
- Use with low loads. Fast acting plug-in relay, with REED contacts.
Energy saving coil <1W.
Switching time <2.5 ms (off-hook) / <3 ms (off-hook).
The RGMV is suitable for:
- Interfaces between protections or automation systems and HV / MV circuit breakers, for the transmission of alarms and very fast trips
- Multiplication of trip contacts in minimum time intervals
2 models: RGMV12 with 4 change-over contacts and RGMV13 with 4 NO contacts
Switching time <8 ms.
The RMMV is suitable for:
- Interfaces between protections or automation systems and HV / MV circuit breakers, for the transmission of alarms and very rapid trips.
- Multiplication of trip contacts in minimum time intervals
2 models: RMMV12 with 8 NO contacts and RMMV13 with 4 NO contacts + 4 NC contacts.
Switching time <6 ms, rebounds included.
The RMMZ is suitable for:
- Interfaces between protections or automation systems and HV / MV circuit breakers, for the transmission of alarms and very fast trips.
- Multiplication of trip contacts in minimum time intervals
Equipped with 8 change-over contacts for exceptional configuration flexibility.
Switching time <8 ms (first contact) + 5 ms (bounces)
