Schneider Make Circuit Breakers are designed on mean opening time or closing time. The value is same for LF1 or LF2 or LF3 Circuit Breakers. It is linked to the operating mechanism RI used for all the LF Circuit Breaker. Mean opening time at Un : 48 ms. Mean Closing time at Un: 65 ms. Where Un =...
The rated Short-Circuit Making Capacity (Icm) for Compact NS Moulded Case Circuit Breaker is as per the table attached and is dependent on the Short-Circuit Breaking Capacity (Icu). (Note: Table is extracted from IEC 60947-2 document) Example: For NS 100 N, 100A MCCB at 440V, Short-Circuit...
In order to gain access to all the Altivar 31 Drive parameters one of the two conditions will apply: 1. Parameter Access Via Standard Keypad (Integrated LED Display): Enter the Customer password in parameter Terminal Locking Code (Cod) in Monitoring Menu (Sup). 2. Parameter Access Via Remote...
Refer the attachment for the internal wiring connection of Motor Mechanism Module (MT100 to MT630) for Compact NS < 630 Moulded Case Circuit Breaker (MCCB).
The part number for a packet of 10 spare cover screws is SEA9FCF
Product standard BS EN 60947-1 defines the ratio n between the peak value and the rms value of the short-circuit current (table 16 on page 106). The rms value must be taken into account for the thermal effect, and the peak value must be taken into account for the electrodynamic effect. The value of...
Following are the difference between XBTZ925 cable and XBTZG925 cable: 1. XBTZ925A and XBTZ925B, in connection with TSX CUSB45 converter, is used for programming HMI terminals: XBT N/R. 2. XBTZG925 is programming cable for XBT GT11xx series HMI terminals only (Serial Tool port).
Please see the attached instructions. NOTE: The MCCB must be in the tripped position before fitting / removing shunt trip or undervolatge coils.
TSXSCPCM4030 cable is required from TSXSCP114 PCMCIA card to the Modbus branching device TSXSCA50 for connecting other RS485 device on the Modbus Network. In case TSXSCA50 Modbus branching device is not used, you can connect this cable directly to Modbus RS 485 device. For this you have to...
