Abb MKCS4 Flange Mechanism Kit Operated Switches

Product Description

The ABB MKCS4 is a flange mechanism kit designed for use with flange-operated disconnect switches. It provides the mechanical actuating components needed to operate a disconnect switch mounted in a flange configuration. Electricians and panel builders use this kit when assembling or replacing the operating mechanism on compatible ABB OS and OT series switches. The kit ensures proper mechanical engagement between the switch handle and the internal switching contacts, maintaining reliable operation and safe manual control of the circuit.

This mechanism kit is suited for use in industrial and commercial electrical installations where flange-mounted disconnect switches are specified. It is referenced for use with the OS200J03 and OT200U03 series flange-operated switches, making it a direct-fit replacement or assembly component for those units. It is appropriate for switchgear enclosures, motor control panels, and distribution boards where the flange mounting configuration is required.

Key Features

• Provides complete flange mechanism assembly for compatible disconnect switches
• Referenced for OS200J03 and OT200U03 series switch applications
• OEM-style replacement for maintaining proper actuator-to-contact engagement
• Supports reliable manual circuit isolation in panel and enclosure installations

Compatibility

Referenced for use with ABB OS200J03 and OT200U03 flange-operated disconnect switches, including OT200U30 variants. Verify switch series and frame size before ordering.

Installation Notes

Installation of this mechanism kit should be performed by a qualified electrician in accordance with NEC requirements and the switch manufacturer's instructions. Always de-energize and lockout/tagout the circuit before servicing or replacing any switch operating mechanism. Confirm that the replacement mechanism is fully seated and that the actuator engages the switch contacts correctly before restoring power.
