V-EA AND MA
CIRCUIT BREAKER
ACCESSORIES
Accessories can be factory or field
mounted on V-EA miniature circuit
breakers and MA motor protection
switches for enhanced control and
monitoring
capabilities.
Field
mounting kits include all necessary
parts and instructions. Accessories
can be gang mounted on a single
breaker (the Auxiliary Switch in the
outside position). The mounting
arrangement links the internal latch-
pins for the tripping mechanisms,
FA
UA
ensuring
simultaneous
trips.

Coil actuated, the FA Shunt Trip allows
electrical remote tripping of a breaker. It
is trip-free and the housing and terminal
specifications are the same as for V-EA
miniature circuit breakers.The Shunt Trip
contains its own contacts which break
the tripping power circuit when tripped. It
is available with trip-coils in most
standard control voltages. The device is
UL and CSA listed for general use.
Re-power your system under controlled
conditions following a power loss or
serious undervoltage. Altech/Sursum UA
Undervoltage Trips are coupled to the
tripping latch pins of the V-EA or MA to
which they are attached, reliably produc-
ing trips at the drop-out voltage and
preventing resetting when less than 85%
line voltage is present. The Undervoltage
Trip is provided with at least 6-inch
pigtails of stranded fixture wire for hook-
up to the V-EA or MA line terminals.
