Reliable Switching for Industrial Power Distribution
The M250E03 provides a safe and reliable means of switching and isolating industrial electrical circuits during normal operating conditions. Simultaneous disconnection of all three phase conductors helps improve maintenance safety while reducing downtime during planned servicing.
Because the M250E03 is supplied as a non-fused load break switch, suitable upstream or downstream overcurrent protection should be selected according to the installation's fault level, conductor sizing and protection requirements. This provides maximum flexibility for industrial electrical designers and panel builders.
Typical Applications
- Industrial switchboards.
- Power distribution systems.
- Motor control centres.
- OEM machinery.
- Generator and transformer isolation.
- Industrial manufacturing facilities.
