can be fitted by the switchboard builder or added
by the end-user. All internal accessories are common for
TemBreak 2 MCCBs.
operating handles and motor operators can be rapidly fitted
using the locking pegs. It takes less than 10 seconds to
secure a handle or motor to the MCCB –
a great time saving compared to alternative products.
accessories are endurance tested to the same level as the
plug-in MCCB is locked to the base when the toggle is
ON. It cannot be removed unless the toggle is OFF or TRIPPED.
The safety lock prevents a trip occurring as the MCCB is being
removed from the base.
cutout patterns for external operating external operating
handles are symmetrical, even when breakers are mounted in
TemBreak 2 MCCBs are fully rated for use at 50ºC. Overheating
is the most common cause of failure in electrical switchgear.
You can reduce the likelihood of overheating by using switchgear
with superior temperature performance.
current ratings up to 630A can be supplied in 2 sizes: the
250A and 630A sizes.
mechanical interlock is installed on the front of the MCCB,
and is compatible with motor operators and external operating
handles. An automatic changeover system can be assembled in
a few minutes by a switchboard builder or end-user.
the heading “Measures to minimise the risk in the
event of failure”, IEC 60204-1 Safety of Machinery-Electrical
Equipment of Machinery includes the following recommendation:
use of switching devices having positive (or direct) opening
