Why Choose the Mersen M315E03 IEC Load Break Switch?
The Mersen M315E03 is a heavy-duty 315 A three-pole IEC non-fused load break switch designed for reliable switching and electrical isolation in industrial low-voltage power distribution systems. It provides dependable load-making and load-breaking performance for substantial three-phase circuits used within switchboards, machinery and electrical distribution assemblies.
Featuring a 0+3 pole configuration, the M315E03 switches all three phase conductors simultaneously while providing no additional switched neutral pole. Its robust base-mounted construction makes it suitable for panel builders and OEM manufacturers requiring a compact yet durable isolation solution for demanding industrial environments.
With a rated operational current of 315 A, the Mersen M315E03 is suitable for incoming supplies, outgoing feeders, motor control centres and production equipment. As a non-fused switch, it allows suitable fuses or circuit breakers to be selected separately according to the fault level, cable size and protection requirements of the installation.

Reliable Switching for Industrial Power Distribution
Load break switches provide a controlled means of connecting, disconnecting and isolating electrical circuits under normal operating conditions. The Mersen M315E03 switches all three phases together, creating a clearly defined isolation point before inspection, servicing or maintenance work begins.
Because the M315E03 does not contain fuse links, appropriate upstream or downstream overcurrent and short-circuit protection must be provided separately. This allows engineers to select protective devices that match the prospective fault current, conductor size and load characteristics of the installation.
Typical Applications
- Industrial low-voltage switchboards.
- Power distribution panels.
- Motor control centres.
- Incoming and outgoing feeder circuits.
- Industrial machinery and production equipment.
- OEM electrical distribution assemblies.
