Isolation Main Switch EATON IS-100/1 (MPN 276282)

EATON IS-100/1 is a main isolation switch designed to provide a clear, accessible point for safe disconnection of electrical circuits. The device creates a visible break in the supply to facilitate maintenance, testing and emergency shutdowns. It is intended for use in residential, commercial and light industrial installations where a single-pole isolator is required to separate circuits from the live supply during service work.

Advantages

The IS-100/1 offers a compact design with straightforward manual operation, enabling quick and unambiguous isolation of a circuit. Its construction provides a visible open position to confirm disconnection, which supports safe maintenance procedures. The switch is compatible with standard DIN-rail or panel mounting arrangements used in typical distribution boards, and it is manufactured to meet industry expectations for robust performance in routine switching and isolation tasks.

Suitable for

• Local isolation of lighting and power circuits in homes and apartments
• Service and maintenance disconnection in small commercial premises
• Temporary isolation during testing and commissioning of installations
• Simple single-pole isolator requirements in light industrial environments

Key specifications

• Function: manual main isolation switch providing visible disconnection
• Poles: single-pole configuration for single-phase circuits
• Operation: manual handle with clear open/closed indication
• Mounting: suitable for panel or DIN-rail mounting in distribution boards
• Application environment: residential, commercial and light industrial electrical installations

How to use

Install the isolation switch in the distribution board or panel in accordance with local electrical regulations and wiring practices. Connect the incoming and outgoing conductors to the designated terminal points, ensuring secure clamping and correct polarity. Operate the manual handle to move the switch to the open position for visible isolation before commencing any maintenance or inspection work. After service is complete, verify wiring and load conditions and return the handle to the closed position to restore supply.

Usage recommendations

Always ensure isolation is confirmed visually and with appropriate test instruments before touching conductors. Use the switch as part of a broader safe-isolation procedure, locking or tagging where required by local safety rules. Regularly inspect the device for signs of wear or loose connections and replace or service it if any damage or abnormal condition is identified.
