NEMA vs IEC. Full
size vs compact size. When it comes to space Siemens has accomplished a
terrific feat by making the entire line of HED43B100 breakers compact
size.Back in the old days believe it or
not televisions were like a giant light bulb and were referred to as the
“tube”, and they were giant and heavy and occupied a large part of any room.
This is the same analogy with I-T-E and present day Siemens circuit breakers.
Some 100 Amp breaker in the past were over 20 inches long and weighed in excess
of 35 lbs. Today the entire line ED43B015 thru ED43B125 and the HED43B015 thru
HED43B125 are 3 inches wide by 5 inches tall and weigh about 3 ½ lbs.
What about adding accessories?
In today’s breaker like the ED42, ED43, ED63, HED43, HHED63
breakers all shunt trips requirements are met by just slapping to the side the
shunt trip modular unit to the side of the breaker. Even a caveman could do it.
Modern technology and the direction of miniaturizing equipment has provided
more product with greater capacity in less environmental room.
Once a customer uses Siemens Sentron thermal magnetic HED43
breakers, they usually like the systems and see them as intuitive and
practical. Here is a list of the high interrupting42 Kiloampere At 480, 3 Pole units at 480 Volts:
HED43B015 HED43B020 HED43B030
HED43B040 HED43B050 HED43B060
HED43B070 HED43B080 HED43B090
HED43B100 HED43B110 HED43B125
Please look at all your options, since there is a breaker
for your specific application. Many accessories like enclosures, shunt trips,
auxiliaries, handle operators, lugs and many more.
