Selection Notes

The Ekip Dip LSI release combines long-time overload (L), short-time delay (S) and instantaneous (I) protection, so the adjustable S stage lets this breaker hold off tripping long enough for a downstream device to clear a fault first, within its 66 kA Icw rating for 1 s and 3 s. Because 1SDA072552R1 ships as the moving part (WMP) only, it has to be fitted into a separate E4.2 fixed part or withdrawable cradle before it can be installed and racked in or out for isolation. Choose the 4-pole WMP variant instead when the installation needs a switched neutral, or a fixed version when the switchboard does not require drawout isolation.
