Why Choose the Mersen M2500E03 IEC Load Break Switch?
The Mersen M2500E03 is a heavy-duty 2,500 A three-pole IEC non-fused load break switch engineered for high-current switching and dependable electrical isolation in industrial low-voltage power distribution systems. Designed for demanding applications, it provides reliable load making, load breaking and manual isolation of substantial three-phase electrical circuits.
Featuring a 0+3 pole configuration, the M2500E03 simultaneously switches all three phase conductors while leaving no switched neutral pole. Its rugged construction and industrial operating mechanism make it suitable for installation within main switchboards, power distribution assemblies, generator systems and large industrial installations.
With a rated operational current of 2,500 A, the M2500E03 is designed for high-power applications including incoming supplies, major feeder circuits and heavy industrial equipment. As a non-fused switch, it is intended to be used with appropriately selected overcurrent protection devices to suit the installation requirements.

Reliable High-Current Circuit Isolation
The Mersen M2500E03 provides a dependable means of switching and isolating high-current electrical circuits under normal operating conditions. Simultaneous switching of all three phases creates a clearly defined isolation point, improving safety during maintenance, inspection and servicing of industrial electrical equipment.
Because the M2500E03 is a non-fused load break switch, suitable upstream or downstream fuse protection or circuit breakers should be selected according to the fault level, cable sizing and protection requirements of the installation. This provides maximum flexibility when designing industrial power distribution systems.
Typical Applications
- Main incoming industrial switchboards.
- High-current power distribution systems.
- Generator and transformer isolation.
- Industrial process plants.
- Large manufacturing facilities.
- OEM power distribution assemblies.
