As previously mentioned, a UL 508 starter is a combination of a UL 508 contactor and
a UL 508 overload relay. Therefore, the use of UL 508 starters also meets construction
Type C.
UL 508 Type D
Construction Type D is very similar to Type C, except that the disconnecting means
and motor branch circuit protection are achieved using a UL 489 instantaneous trip
circuit breaker rather than an inverse time circuit breaker. Schneider Electric has
various products that meet this construction type, as listed below.
Just as for Type C, the use of UL 508 starters also meets construction Type D.
UL 508 Type E
Construction Type E is a unique situation in that all four functions are achieved using a
single device. For this reason, Type E is known as a self-protected combination motor
controller. Schneider Electric has two product families that meet this unique construction
type, TeSys U and TeSys GV. TeSys U is a self-protected combination motor controller
while TeSys GV is a manual self-protected combination motor controller.
