MITSUBISHI Electric Australia has released the VZ-D series of vacuum contactors and combination units, enhancing its range of medium voltage switchgear.
The size of the units has been reduced and their safety improved. Live parts have been fully enclosed by insulators, while the overall unit remains compact and lightweight.
The units are suitable for the restricted spaces of mining operations.
The vacuum contactors are rated at 7.2kV/3.6kV and can be supplied as rated currents of either 200A or 400A. The standard product is 4kA rated, but can be supplied as a combination switch with power fuses, taking the rating up to 40kA.
