Instantaneous relays
BM 400 relay - Mixed load, 4 contacts
Summary
Description
The BM 400 relay has 3 silver double make / double break C/O contacts (form Z) and one gold bifurcated C/O contact.
The plug-in design offers secure locking feature for maximum ease of maintenance (no wires need to be disconnected or other hardware removed for relay inspection or replacement).
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 BM 400 relays is pluggable in the following sockets: EA 102 B, EA 102 BF, EA 103 BF, EA 104 B, EA 104 BF, EA 105 BF, EA 112 BF.
Application
The BM 400 relay is designed for both power levels and low level signals are being switched for general purpose heavy duty applications such as lighting, pumps and fans, as standard weld no transfer design for safety critical applications such as door control, emergency brake failure, interlocking traction
and breaking with a gold bifurcated contact for dry circuit signal information.
and breaking with a gold bifurcated contact for dry circuit signal information.
