• Rated short-time withstand current up to 25 kA (1 s)
• Arc fault tested up to 25 kA (1 s)
• Type-tested to IEC 62271-200, LSC2B-PI, IAC AFL
• For circuit breakers, contactors and load-break switches with and without HRC fuses
• Permanent fitting with movable contacts
• Extendable switching components for maintenance purposes

Sepecial feature of MC3-S
The innovation of this switchgear is the movable contact to create the isolating distance.

Switching compartment:
In the switching compartment the switching component is fix mounted to the baseplate. The position indicator and operating elements of the switch component are directly integrated into the High-Voltage-Door.

The connections of the switching component are conducted through a standard-duct onto the rear contacts. The ceation of the isolating distance occurs through moving the contacts.

The switch position indicator is mechanically coupled with the motor behind the front.
