The TD/TS Series MCCB–molded case
circuit breakers–main function are to protect
electrical applications form short circuit or
earth leakage, overload current and
under-voltage conditions. These devices
are used to isolate the power, or to trip
the power, at the time of fault in line and
thus save the circuit from further damage.
MCCB’s are well suited for OEM designed
equipment in both light commercial and
industrial applications. Their compact size
saves space and reduces overall panel size
and the field-installable accessories allow
for last minute changes.

The TD/TS Series MCCB’s are available with
three different trip units that are installed in
the housing; FTU–fixed-thermal and fixed
magnetic; FMU–adjustable-thermal and
fixed magnetic; ATU-adjustable-thermal and
adjustable-magnetic. The following internal
electrical accessories are also available
auxiliary and alarm switches, shunt releases,
and under voltage releases. See the online
manual for additional information and trip
