Informatie
Description
The AK 400 relay has 4 double make / double break C/O contacts (form Z). It is conform the French standard NF F 70-031 section 7.1.2. and 7.1.3. which specified no welding when contacts are closed on a 200 Amps 30 V short circuit protected by 6 A/400 V G1 fuse and no welding when contacts are closed on a 200 μF capacitor charged at 330 VDC.
The resistance to impact and vibration is conform to standards in force for Railway Transported Equipment.
Positive mechanical keying of relay to socket is built into relay and socket during manufacture and terminal identifications are clearly marked on identification plate that is permanently attached to the relay.
The AK 400 relays is pluggable in the following sockets: EA 102 A, EA 102 AF, EA 103 AF, EA 104 A, EA 104 AF, EA 105 AF, EA 112 AF.
Application
The AK relay is designed heavy duty applications where a high degree of resistance to welding is required. Stationary contacts are silver tin oxide. Mobile contacts are hard silver laminated to copper. In a power interruption situation relay armature will assure a “safe” position. This is due to the strength of the 2 compressed springs which pushes the armature back into the rest position.
