iMSSB – Switchboard

Product Code: iMSSB

iHVAC proudly presents our highly customised mechanical switchboards, the iMSSB, because intelligent controls without a central processing unit (CPU) are like a brand-new electric vehicle that won’t start because of a software glitch. With an option to upgrade to an interactive HMI 7” touchscreen, our boards are so easy to use that one can operate without prior training.

Custom-built for every project by our highly qualified electrical engineering team at iHVAC and factory tested and pre-commissioned before despatch, the iMSSB comes with wiring diagrams and is ready to be installed by your qualified electrician. All you need is to just ‘Plug and Play’.
