Page 4: General
Figure 1.1-1. Arc protection unit VAMP 121 1.2. Unit features VAMP 121 is a state of the art arc protection unit for electrical power distribution systems. By using VAMP 121 in switchgears considerable safety improvements are obtained in the form of minimized injury and damage in case of an arc fault. -
Page 5: Unit Configuration
System Fault alarm is activated. The same function is attained by activating the binary input on connector X2-7, X2-8 (see also inputs). When the blocking function is activated, the error led is lit and the SF-relay activated.

Page 11: Switchgear Application
User manual Switchgear application Every compartment is equipped with an arc sensor. Up to ten sensors can be connected to the VAMP 121 unit. The trip relay is electromechanical and can be connected directly to control the circuit-breaker (see specifications). -
Page 12: Connections
Figure 7-1. VAMP 121 system components 7.1. Outputs The VAMP 121 unit has an integrated relay output (X2-15,X2- 16) for tripping of the circuit-breaker. Furthermore, one binary output is available (+24V dc) X2-9 (-) X2-10(+), which becomes inactive (0V) on internal fault (SF) and / or on tripping (configurable). -
Page 13: Inputs
VAMP 121 User manual 7.2. Inputs VAMP 121 has 10 arc sensor inputs X1:1-20, and one connection for a portable arc sensor (VA 1 DP). All these inputs have continuous self-supervision. Furthermore, one binary input is available for blocking of the output relay e.g. -
Page 14: Auxiliary Voltage
90...250V dc. The output (+24V dc) on the voltage module MINI-PS is connected directly to the terminals X2-1 (+) and X2- 2 (-) on VAMP 121. If the auxiliary voltage in the switchgear is 24V dc it can be directly connected to the terminals X2-1 (+) and X2-2 (-) on VAMP 121. -
