Isolating switch Noark Ex9I125 3-pole 63 A (model 100876)

The Noark Ex9I125 3-pole isolating switch 63 A (model 100876) is a compact manual electrical disconnector designed to provide visible and reliable circuit isolation for maintenance and safety operations. Intended for industrial and commercial installations, the switch offers straightforward mechanical operation and clear separation of three-phase circuits. The device is built to be mounted in switchgear or on distribution panels where safe manual disconnection and visual confirmation of open contacts are required.

Advantages

The isolating switch provides visible disconnection of all three poles, enabling technicians to confirm circuit separation quickly and reduce the risk of accidental re-energization during service. Its compact design saves panel space while delivering a stable 63 A switching capacity suitable for many distribution and control applications. The manual operating mechanism is simple to use and requires no auxiliary power, supporting dependable operation in environments where electrical isolation must be assured.

Suitable for

• Isolation of three-phase circuits in industrial switchboards and distribution panels
• Safe maintenance and servicing of motors, machinery, and control equipment
• Temporary disconnection during electrical testing and commissioning
• Use in commercial electrical installations requiring manual visible disconnection

Key specifications

• Number of poles: 3 (three-pole isolation)
• Rated current: 63 A
• Operation: manual mechanical handle for on/off with visible open contacts
• Mounting: panel or switchgear mounting compatible with standard distribution enclosures
• Contact type: positive visible breaking across all poles for safe isolation

How to use

Install the isolating switch on a suitable panel or inside a distribution cabinet following local electrical codes and the manufacturer's mounting instructions. Connect the incoming and outgoing conductors to the respective terminals, ensuring tight and secure connections. Operate the manual handle to switch between ON and OFF positions; the visible separation of contacts confirms the isolated state. Locking or tagging procedures can be applied while the switch is in the OFF position to support safe maintenance work.

Usage recommendations

Verify compatibility with system voltage and protective devices before installation, and perform installation and servicing only by qualified personnel. Regularly inspect terminal connections and the mechanical operation of the handle to ensure reliable isolation, and follow local safety regulations for lockout-tagout procedures during maintenance.
