Motor Control Centres (MCC)

Overview

Engineered Motor Control Centres

NPE designs, fabricates and tests Motor Control Centres (MCCs) in our Nairobi facility to IEC 61439-1 & 2 standards. Our MCC lineups centralize motor starting, power distribution, energy metering, and process interlocking in heavy-duty cubicles engineered for the most demanding agro-processing, chemical, and water utility installations.

Available in Form 2b, Form 3b, and Form 4b internal segregation, each starter compartment is segregated to isolate electrical faults and enable maintenance on individual feeders without interrupting adjacent running processes.

FAQs

Type 2 coordination guarantees that following a short-circuit fault, the contactor and overload relay suffer no damage and can immediately return to service without component replacement.

Yes. We engineer back-to-back, L-shaped, and front-access-only MCC configurations with bespoke heights and cable box orientations to fit existing plantroom constraints.
