Why Choose the Mersen M200E03 IEC Load Break Switch?
The Mersen M200E03 is a robust 200 A three-pole non-fused load break switch designed for dependable switching and isolation in low-voltage industrial power distribution systems. Engineered for demanding electrical applications, it provides a reliable means of manually connecting and disconnecting three-phase circuits under normal load conditions.
Featuring a 0+3 pole configuration, the M200E03 switches all three phase conductors simultaneously while leaving no additional switched neutral pole. Its compact, industrial-grade construction makes it suitable for installation within switchboards, distribution panels, machinery and electrical control assemblies where dependable circuit isolation is required.
The Mersen M200E03 is designed to comply with IEC load break switching requirements and supports operating voltages of up to 690 V AC, subject to the electrical characteristics of the application. As a non-fused device, it can be paired with separately selected fuses or circuit breakers to provide the required overcurrent and short-circuit protection.

Reliable Isolation for Industrial Power Systems
Load break switches are used to safely connect, disconnect and isolate electrical circuits during normal operating conditions. The Mersen M200E03 provides simultaneous switching of all three phase conductors, helping create a clearly defined isolation point for maintenance, inspection and equipment servicing.
Because the M200E03 is a non-fused switch, suitable overcurrent and short-circuit protection must be installed separately. This arrangement allows engineers to select fuses or circuit breakers that match the cable size, load characteristics, prospective fault current and protection requirements of the electrical installation.
Typical Applications
- Industrial low-voltage switchboards.
- Electrical distribution panels.
- Motor control centres.
- Industrial machinery and production equipment.
- Incoming and outgoing feeder circuits.
- OEM electrical control assemblies.
