Adjustable type MCCB(GB-type)

(100�250 Ampere Frame)
The NEW Meta-MEC series was developed as an adjustable type and has high
performance and multi-function under modern design concept

Remarkably increased breaking capacity meets the customer's need in the trend
of steadily increasing the capacity of a transformer

The rated current and instantaneous current are adjustable and that solves the
load control and stock management problems

Accessories are made in the customer's side concept, and new accessories such
as rear connection terminal and E-handle are available with the standard
offered accessories
