Suitable for

• Residential electrical distribution boards
• Industrial control panels
• Emergency power disconnection systems
• Maintenance isolation for lighting and small appliance circuits

When it may not be suitable

This device is a 1-pole switch and is not suitable for applications requiring the simultaneous disconnection of neutral and phase conductors or multi-phase systems. It should not be used in environments where the current load exceeds the 25A rating, as this could lead to overheating and device failure.

Key specifications

• Rated current: 25A
• Number of poles: 1
• Mounting type: DIN rail
• Operational voltage: Suitable for standard low-voltage systems
• Design: Modular

How to use

The Eaton IS-25/1 should be installed by a qualified electrician in accordance with local electrical regulations. The device is designed to be snapped onto a standard 35mm DIN rail within a distribution enclosure. Once mounted, the input and output cables are connected to the respective terminals, ensuring all connections are tightened to the manufacturer's specified torque. The switch is operated manually via the front toggle, which provides a clear visual status of the circuit state.

What to consider before purchase

• Verify that the 1-pole configuration meets your specific circuit requirements.
• Ensure the 25A rating is sufficient for the intended load.
• Check the available space in your distribution board for modular DIN rail components.
• Confirm compatibility with existing electrical infrastructure and safety standards.

Usage recommendations

Regularly inspect the switch for any signs of physical damage or loose connections. It is recommended to perform a functional test during scheduled maintenance to ensure the switching mechanism remains smooth and responsive.
