Internal Accessories
Internal accessories include Auxiliary and Alarm contacts, Shunt Trip and Undervoltage Trip (UVT) modules, which may be installed under the front cover of
the MCCB in various combinations to provide additional functionality and connection with external control circuits.
Auxiliary & Alarm Switches
Auxiliary Contact
An auxiliary contact can be installed to indicate whether an MCCB is Open (both OFF and
Tripped positions) or Closed (ON). Auxiliary contacts come in either general purpose, heavy
duty or micro-switch type, with some combinations pre-wired or with terminals. Each contact
type is provided as a single change-over switching arrangement (1x C/O), or normally-open
(1x N/O) for option in heavy-duty.
Alarm Contact
An alarm contact can be installed to indicate whether an MCCB is in the Tripped or Not
Tripped position (ON, OFF). Alarm contacts come in either general purpose, heavy duty or
micro-switch type, with some combinations pre-wired or with terminals. Each contact type is
provided as a single change-over switching arrangement (1x C/O), or normally-open (1x
N/O) for option in heavy-duty.
