- Compliant with RFI P/N 781/220
- 2 changeover contacts rated 10 A + 1 fault contact (N.O.)
- Self-cleaning knurled contacts
Description
MAMF12 monostable instantaneous auxiliary relays feature very high insulation and are used on power plants and electric traction systems.
These devices are installed in voltage monitoring systems for power line harmonic filter equipment requiring compliance with RFI P/N 781/220
Ultra-high insulation: up to 12 kV (withstand voltage at industrial frequency) / 20kV (impulse withstand voltage).
Knurled operating contacts to provide lower ohmic resistance thanks to the multiple electrical connection points: extended electrical life expectancy of the component, excellent performance for strongly inductive DC loads and for very low loads, as in the case of interface signals. Optional magnetic arc blow-out for higher breaking capacity.
