Low voltage switchgear

MODUL-K-MCC-SYSTEM

Motor Control Center (MCC)

Motor control center (MCC)

Our type-tested and accidental arc tested withdrawable system employs the latest patented technology for safe plug-in contacting.

Characteristics

An internal arc-free plug-in bus, the insulation-encapsulated contact module with a mechanical lock for operational error protection, plus operating, isolation and test positions with the compartment door closed ensure maximum safety for operators and protection of machinery.

As a member of the MODUL-K-SYSTEM family the Motor Control Center (MCC) is also earthquake and shock tested. For perfect delivery worldwide, even under the harshest shipping conditions.
