  Delta XRD Compact supervision relay

  The Delta XR Series Relays are low burden electro-mechanical supervision relays for application on high security tripping and auxiliary supply circuits. The Delta XR relays have been designed to provide a balance of low burden to minimize the possibility of circuit breaker maloperation while maintaining a minimum contact whetting current to avoid nuisance alarm conditions.

  Delta XRD-8 Trip Circuit Supervision Relay

  The Delta XRD-8 has been designed to specifically operate with magnetic actuated circuit breaker control modules. Supervision currents have been chosen to ensure reliable differentiation between supervised and tripped conditions. A green Healthy LED is standard. Failure of the circuit or supply being supervised will cause the main relay element to drop out, an alarm signalled via the red LED and the alarm contacts to change state. The Delta range…

  MSA305 – current sensor 300 A

  The industrial current sensors are based on compensating the magnetic field by a closed loop system. The MSA305 is used for the measurement of AC and DC currents with high galvanic isolation between the current carrying conductor and output of the sensor. The current sensor can handle pulsed currents. The MSA305 is especially designed for secure measuring of a permanent current up to 300A. The current measuring range covers a…
