The breaking capacities of Meta-MEC Series are increased 5 to 20% higher than those of other existing products. high interrupting type and current limiting types are identical within a AF. The frame size of MCCB is same as ELCB in the same rating: the frame sizes of the economical type, standard type. Moulded Case Circuit Breaker Rationalization of Frame Size. This function allows users to directly adjust an instantaneous trip current. While an ordinary product has the fixed characteristics of instantaneous operation, new MetaMEC has a function to adjust the characteristics of instantaneous operation. And the number of mountable internal accessories is increased.ДЄdjustable Characteristics of Instantaneous Operation. Use of auxiliary cover and optional accessories in the form of cassette allow user to easily attach or replace accessories. Easy to Mount and Change Optional Accessories. Rated currents can be easily adjusted within a same frame MCCB by simply c hanging the Rating Plug, which can change rated currents. Meta-MEC Series (400AF to 800AF) Adjustable Rated Current.

The identically sized frames of MCCB and EL CB allow users to interchange MCCB with ELCB. (Reduced height of nameplate protrusion from 99mm to 60mm enables to compose ideal panels.) MCCB and ELCB with identical size. Panel designing and manufacturing are standardized with the unified dimensions of 24mmhigh terminal base and 60mm-high nameplate protrusion. For the economical type, standard type, high interrupting types of MCCB 225AF, the model with rated current of 100A is added. Moulded Case Circuit Breaker Increased Variety.

Micro Processors Based Electronic Trip MCCBД¦, Vanrai Complex, W E Highway, Goregaon (E), Mumbai вЂ“ 400065. The AB type frame has the same size as the existing Hi-MEC Series, and it allows trouble-free application of product to distribution panel.

GB Type - 100AF & 250AF MCCB Easy to Mount Optional Accessories Free usage Equipped with an open-close type auxiliary cover, users can easily mount optional accessories. Increased Breaking Capacity The breaking capacities of new Meta-MEC Series are increased 80% to 90% higher than those of the existing Hi-MEC Series (based on voltage of 460VAC). This feature allows easy application of design with an appropriate breaking capacity Formation of Series According to Breaking Ratings (capacity) MCCB has four (4) types of breaking capacities economical type, standard type, high interrupting type and very high interrupting types. Various Ratings MCCB has a variety of rated current frame from small to large capacities (30AF~1200AF). Characteristics MCCB and ELCB (Earth Leakage Circuit Breaker) with the same size this features interchangeability interchangeabilit y and construction with modularized panel since the size of MCCB is the same as an ELCB in the same frame. MCCB can automatically cut off electric power in case of overload and short circuit. Moulded Case Circuit Breaker Moulded Case Circuit Breaker 5A to 1600A Outline MCCB, in which a circuit breaker and trip device are assembled in a mould case, can manually or electrically open and close the electric circuit.
