Schneider Electric Acti9 iC60 OF Auxiliary Contact

OF auxiliary contact for the Schneider Electric iC60 breaker: auxiliary signalling and intelligent distribution-board monitoring

Transmission of precise digital status signals to monitoring systems

• Sending signals through the OF auxiliary contact:This architecture allows theOF auxiliary contactto send clean, low-level status signals to monitoring systems so they can confirm the state of the associated circuit and improve operational visibility on site throughGahzly.

Easy side mounting and secure attachment to support operational readiness

• Secure mounting:TheOF auxiliary contactunit is designed for straightforward side installation with secure mechanical attachment, helping it remain stable even in environments subject to vibration on site throughGahzly.

Operating mechanism and functional interaction of the OF auxiliary contact

• The physical principle behind mechanical status transfer:The operating principle ofOF auxiliary contact(Open/Close) is based on converting the physical movement of the miniature circuit breaker handle (iC60 MCB) into a voltage-free electrical signal (Volt-free contacts). When the user raises the breaker handle to the ON position, the internal parts of theOF auxiliary contactunit move mechanically to change the state of its contacts: the normally open (NO) contact closes and the normally closed (NC) contact opens to signal the control systems withinGahzly.

• Role of the unit in comprehensive monitoring and control:TheOF auxiliary contactunit enables engineers to integrate conventional breakers into smart-building systems or SCADA monitoring panels by providing immediate, reliable feedback on the state of each branch or main breaker within the installation.

Installation engineering and field wiring of the OF auxiliary contact

1. Side mounting on the iC60 breaker:Installation starts by fully disconnecting the electrical supply, then mounting theOF auxiliary contactunit on the designated left or right side of the iC60 breaker using the mechanical fastening points designed for quick engagement.

2. Connecting signal wires and the control system:The auxiliary-contact terminals of theOF auxiliary contactunit (NO, NC, and Common) are connected to low-current control-signal wiring, with the terminal screws tightened securely on site throughGahzly.

Technical specifications and functions table

Objective advantages and limitations

• Key advantages:

  • Immediate and accurate breaker-status feedback provided byOF auxiliary contactwithin the installation.Gahzly.

  • Very easy side installation and secure mechanical engagement with the iC60 breaker.

  • Flexible signalling through both normally open and normally closed contacts (NO/NC).

• Limitations and considerations:

  • TheOF auxiliary contactunit is intended only for auxiliary signalling and does not itself interrupt power or provide protective tripping.

  • It requires a small amount of additional space beside the breaker inside the distribution board.

Suitable and unsuitable applications

• Ideal applications:

  • Control and monitoring panels in large industrial facilities and commercial buildings usingOF auxiliary contactthroughGahzly.

  • Building Management Systems (BMS) and automation control rooms that require real-time indication of load or breaker status.

• Unsuitable applications:

  • Use as a substitute for a compatible main protective breaker in high-power circuits.

  • Installation in environments directly exposed to liquids without a suitably rated IP-protected enclosure.

Safe operation and installation method

1. Complete Electrical Isolation:Disconnect the main supply to the distribution board and measure the voltage to confirm that it is fully de-energized before starting work on site throughGahzly.

2. Mechanical side installation:Mount theOF auxiliary contactunit on the designated side of the iC60 breaker and confirm that the coupling lever engages correctly.

3. Electrical signal wiring:Connect the monitoring-circuit wires to the auxiliary-contact terminals and tighten the terminal screws securely.

4. Field verification test:Restore power and operate the breaker handle to verify signal transfer and correct operation of the status indicators throughOF auxiliary contact.

Important safety notice: Never use theOF auxiliary contactunit to carry high-current loads or main power circuits; it is intended exclusively for low-current control and monitoring signals.

Maintenance, cleaning, and extending service life

• Periodic inspection of connections:Regularly inspect the terminal screws of theOF auxiliary contactunit for any loosening.

• Distribution-board cleanliness:Keep the panel free from dust and moisture to protect the unit’s precision mechanical and electrical components.

Important advice before purchase

• Checking model compatibility:Confirm that your breaker belongs to the iC60 range so that it is fully compatible and mechanically engages correctly with theOF auxiliary contactunit before purchase throughGahzly.

• Use Genuine, Traceable Products:Source the correct Schneider Electric breaker fromGahzlyto obtain the specified engineering quality, signalling accuracy, and long-term safety performance.

Comprehensive conclusion

TheOF auxiliary contactThe OF auxiliary contact for the Schneider Electric iC60 breaker is a practical accessory for improving monitoring and control in modern distribution boards. Its side-mounted mechanical linkage, NO/NC status signalling, and compact installation provide immediate visibility of breaker state. Selecting the correct genuine accessory and sourcing it throughGahzlyis an important step toward improving automated supervision, maintaining reliability, and supporting professional electrical installations.
