Product Description

Arteche RPT Voltage presence indicators Arteche Supervision relays

• Surveillance voltage presence relay for three phases.
• Lights on the nameplate, and output contacts.
• Mounting in rail DIN box or flush mounted.

Arteche trip circuit supervision relays monitor trip coil circuit in open/close states and during circuit breaker operation. TCS relays are used for DC supervision via LOR trip coil, generating an alarm and avoiding open/close commands under faulty conditions or when breaker tripping mechanism is not ready to operate.

With references for single pole and 3 pole and a wide range of voltages, VDF / VDJ trip circuit supervision relays performs monitoring functions over circuits, fuses, and MCBs involved in the control power supply circuit of switchgears and other critical control circuits.

Suited for demanding applications in substation environments, RUT trip supply supervision relays generate an alarm and avoid open/close commands if the power supply circuit of a circuit breaker is under faulty conditions.

Supervision relays

Continuous surveillance of the trip circuit, in any position of the circuit breaker (open or closed) as well as during the change of position:

Trip Circuit Supervision Relays

State of the contacts change when the trip supply is lost providing alarm:

Auxiliary Trip Supply Supervision Relays

 Variants for single pole or three pole circuit breakers

 Front LED indicating state of the circuit and two output contacts to provide alarm

 Independent surveillance increasing safety of the system

Operation delayed to avoid undesired alarms due to voltage dips
