Commercial building electrical systems
Maintenance isolation for machinery and equipment

When it may not be suitable

This device is not intended for use as a circuit breaker for overload or short-circuit protection, as it lacks internal trip mechanisms. It should not be installed in environments exceeding its specified environmental ratings or in applications requiring higher current capacities than 100A.

Key specifications

Number of poles: 4
Rated current: 100A
Weight: 391 g
Dimensions: 101 mm width, 78 mm depth, 89 mm height

How to use

The switch should be installed by a qualified electrician onto a standard DIN rail within an appropriate electrical distribution board. Ensure that all cable connections are tightened to the manufacturer's specified torque settings to prevent overheating. Once installed, the switch is operated manually via the front-facing toggle to disconnect or reconnect the power supply to the downstream circuit.

What to consider before purchase

Verify that the 100A rating is sufficient for your specific load requirements.
Ensure the 4-pole configuration matches your circuit topology.
Check the available space in your distribution board against the physical dimensions of the unit.

Usage recommendations

Always verify that the circuit is de-energized using a calibrated voltage tester before performing any maintenance work on the downstream equipment, even when the isolating switch is in the off position.
