The NTBBOR 400 is a delay-on-drop-out relay with negative command and 4 double make / double break C/O contacts (form Z). The delay is fully programmable via a dip switch from 0.25 s to 63.75 min, accessed by removing the cover to prevent frivolous field settings. The plug-in design offers a secure locking feature for easy maintenance. Resistance to impact and vibration conforms to railway equipment standards, with positive mechanical keying. The relay plugs into the EA 102 B, 103 BF, 104 B, 104 BF, 105 BF and 112 BF sockets.
