TBAA 400 relay - Delay-on pull-in, 4 C/O
Summary
Description
The TBAA 400 is a delay-on pull-in relay with 4 double make / double break C/O contacts (form Z). The time delay is less than 10 s and fixed.
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 TBAA 400 relay 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 TBAA 400 timing relay is designed for heavy duty applications with a programmable timing function used for example in HVAC and lighting.
