Fast delivery and easy installation with Eaton’s new MCCB


A new moulded-case circuit-breaker range, announced by Eaton,
offers installers an extremely adaptable MCCB, independently certified by KEMA
to the international switchgear standard IEC60947-2. Series G MCCBs are
typically 30% smaller than existing units and the range covers applications from
16A to 2,500A in just five frame sizes.



Eaton has invested £1 million in a new Component Assembly
Centre in Reddings Lane Birmingham to offer "Late Point Definition" of Series G
MCCBs and other devices. Stocks of the basic MCCB are held, together with a full
complement of accessories (auxiliary switches, alarm switches, shunt trips,
undervotage releases etc.) so that devices can be configured quickly for rapid
turn-round. The distinction between "standard" and "special" devices disappears
as all units are assembled, tested and despatched within hours of an order being
received.



Series G MCCBs are designed for easy installation and
reconfiguration. A choice of box clamp or bolted terminations up to 630A, offers
a wide range of termination options for cables, cable lugs or busbar
connection.



Accessories are a plug-in design that can be field-fitted
easily and safely from the front. These accessories are common across the three
smaller Frame Sizes, from 16A to 630A, covering the majority of needs. They
include alarm switch, auxiliary switch, shunt trip, low-energy shunt trip and
undervoltage release units. All are certified for on-site installation.



Series G is the first MCCB range to boast the internationally
respected KEMA-KEUR mark. This certifies that the product has been
independently tested for compliance with IEC 60947-2 and that production
will be subject to ongoing surveillance.



Series G MCCBs employ a patented contact mechanism with
high-speed "opening force action" ensuring minimum energy let-through under high
fault current conditions. Interrupting capacities up to 100kA are available on
units as low as 250A. Units are calibrated for a 40°C ambient but 50°C can be
supplied.



The smallest frame size, Frame GE, offers ratings of 125A and
160A, covering the current range 16-160A with fixed or adjustable thermal trip
and fixed magnetic trip units. The second frame size, Frame GJ, is a versatile
250A unit available with adjustable thermal-magnetic trip or electronic trip.
The electronic trip enables the breaker to be used effectively down to 20A. The
third frame size, Frame GL, comprises 400A and 630A units, also with adjustable
thermal-magnetic or electronic trip options. Larger Frame GN and GR units are
designed for special applications and come in 800-2500A ratings.



"We are confident that Series G will offer contractors and
panel builders an unparalleled range of moulded-case circuit-breakers, backed by
the assurance of the KEMA-KEUR mark and available on a just-in-time basis from
the new Component Assembly Centre in Reddings Lane" says David Pitt, Product
Manager – Circuit Protection.



Eaton has already launched a new range of its MEM panelboards
designed around the Series G circuit-breakers.
