Suitable for

• Industrial electrical distribution panels
• Residential consumer units
• Safe isolation of electrical circuits during maintenance
• Emergency power disconnection systems

When it may not be suitable

This device is not intended for use as a load-break switch for frequent motor starting or stopping operations. It is designed primarily for isolation purposes and should not be used in circuits exceeding its 16A rated current capacity.

Key specifications

• Rated current: 16A
• Number of poles: 4
• Mounting type: DIN rail
• Function: Main isolator switch

How to use

The Eaton IS-16/4 should be installed by a qualified electrician within a suitable electrical enclosure. It is mounted onto a standard DIN rail inside the distribution board. Once installed, the switch is operated manually using the front-facing toggle to connect or disconnect the power supply. Ensure that the wiring is correctly terminated according to local electrical regulations to maintain the integrity of the circuit.

What to consider before purchase

• Verify that the 16A current rating is sufficient for your specific circuit load.
• Ensure the 4-pole configuration matches your electrical system requirements.
• Check the available space in your distribution board for modular DIN rail mounting.

Usage recommendations

Always verify that the circuit is de-energized using a voltage tester before performing any maintenance work, even after the isolator switch has been turned to the off position.
