NZM-S1 Moulded Case Circuit Breakers for 1000 VAC applications
NZM-S1 Moulded Case Circuit Breakers for 1000 VAC
applications, completes the NZM range for sectors where
higher network voltages are present.
Tested according to IEC60947 the NZM-S1 covers from 20A
to 1600A with Icu/Ics values up to 20/15kA at 1000VAC. Trip
units are segregated for Selectivity and Motor Protection with
electronic and thermal magnetic versions. Switch Disconnector
versions are also available.
The NZM-S1 range is suitable for use in rugged environmental
conditions such as mines, road tunnels, refineries, chemical
plants and railways. Typical applications include protection
of drives for high performance and general industrial power
distribution networks with long supply lines.
The NZM-S1 utilizes the same suite of accessories as the
standard range of NZM Moulded Case Circuit Breakers.
