VFD / AC Drive Panel
AC drive panels built around variable frequency drives to control motor speed, save energy on pumps and fans, and give smooth starting.
Motor Control & Automation
Motor Control Centre (MCC)
Motor control centres with fixed or draw-out starter feeders that start, protect and control the motors in your plant from one panel.
- Starter types
- DOL, star-delta, soft starter, VFD
- Feeder type
- Fixed or draw-out
- Busbar
- Aluminium, e.g. 400 A
- Operating voltage
- 380 / 415 / 440 V AC, 3-phase, 4-wire
Overview
A motor control centre (MCC) groups the starters for many motors into one panel, each with its own protection, controls and indication. It makes operation, maintenance and fault-finding simpler than scattered starters.
We build MCCs with fixed or draw-out feeders to your motor list, using DOL, star-delta, soft-starter or VFD starters as each motor requires.
Key features
- Fixed or draw-out starter feeders
- DOL, star-delta, soft-starter and VFD feeders
- Overload and short-circuit protection for every motor
- Local/remote control with run and trip indication
- Busbars and feeders sized to your motor list
