Phase sequence indicator ISE

illuminatedpanel

Phase sequence indicators allow to determinate the phase sequence in a 3-phase network. They use an electric circuit, without moving parts. When the instrument is connected, if the phase-sequence is correct a grenn light shices. Otherwise, a red light does. – ISE72n/1 and ISE96n/1: Indicators for panel mounting are suited for permanet connections at voltages between 150 and 600V. – ISE 96s/2: Indicator for panel mounting. It also incorporates a change-over relay, with potential-free output contacts. When the sequence is not correct or the instrument is disconnected, the relay de-energizes (closed circuit principle). Thus, an alarm can be triggered or any corrective action can be taken. Technical Features ISE96/2: Voltage: 110 / 230 / 400 / 440 V 50 or 60 Hz Switching range: UN +20 % up to -20% UN Relay output: 1 isolated change-over contact (changer) Switching capacity at ohmic load: 1 x106. Maximal switching current: 6 A, 250 V max. 300 W at alternating voltage
