Description
The trip circuit supervision relay EB143887SPER 1C1-AA is used for supervising important control circuits, such as, circuit-breaker and disconnector control circuits and signalling circuits in power electrical installations. Generally, one supervision relay is needed per circuit to be supervised. If several branches of a circuit are to be supervised, the required number of relays can be connected to the same control circuit.
Parameters
Voltage of the circuit monitored: 40-265 V dc
Measuring current: 1.5 mA, typ.
Min. residual voltage over the circuit monitored: >40 V dc
Auxiliary supply voltage and current:
rated voltage Un:48/60/110/220 V dc
operation volt:40-265 V dc
Current drain, typ.:7 mA
Frequently Asked Questions
Q:What is a EB143887SPER 1C1-AA realy?
A:The Sper 1C1-AAJ is mechanically designed to suit the COMBIFLEX system. The relay supply voltage range is 40-265 V DC.
Q:How much current does a EB143887SPER 1C1-AA use?
A:The supervision relay can be connected to receive the supply voltage from the control circuit monitored, over the connection wires of the driver circuit. A condition, however, is that the control coil of the circuit monitored is not affected by the increased current consumption of about 7-16 mA, depending on the type of supervision relay, and that the residual voltage over the circuit monitored is above 40 V dc.
Q:In which applications is EB143887SPER 1C1-AA typically used?
A:It is used to supervise circuit breaker control circuits, disconnector control circuits, and signalling circuits in power installations and substations.
