Why Choose the Mersen M250E30S IEC Load Break Switch?
The Mersen M250E30S is a robust 250 A three-pole IEC load break switch designed for dependable switching and electrical isolation in industrial low-voltage power systems. Its non-fused construction provides a reliable means of manually connecting and disconnecting substantial three-phase loads while allowing overcurrent protection to be selected separately.
Featuring a 3+0 pole configuration and a right-hand side-operated mechanism, the M250E30S is particularly suited to switchboard and enclosure layouts where side operation is required. All three phase conductors are switched simultaneously, creating a clearly defined isolation point for inspection, maintenance and equipment servicing.
With a rated operational current of 250 A, the M250E30S is suitable for industrial feeders, machinery supplies, motor control centres and electrical distribution assemblies. Its compact construction and durable switching mechanism support reliable operation in demanding industrial and commercial installations.

Reliable Side-Operated Circuit Isolation
Load break switches provide a controlled method of switching and isolating electrical equipment under normal operating conditions. The Mersen M250E30S disconnects all three phase conductors together, helping ensure downstream equipment is electrically isolated before maintenance, inspection or repair work begins.
The right-hand side-operated arrangement provides additional flexibility for customised switchboards and machinery enclosures. Because the M250E30S is a non-fused device, suitable fuses or circuit breakers must be installed separately to provide the required overload and short-circuit protection.
Typical Applications
- Industrial low-voltage switchboards.
- Power distribution panels.
- Motor control centres.
- Industrial machinery and production equipment.
- Incoming and outgoing feeder circuits.
- OEM electrical control assemblies.
