Thermal Circuit Protectors
This catalog features Carling Technologies current line of thermal circuit protectors, from 3 to
60 amps, which offer reliable, cost effective circuit protection.
Thermal circuit protectors utilize a bimetallic strip electrically in series with the circuit. The
heat generated by the current during an overload deforms the bimetallic strip and trips the
breaker.
Thermal protectors have a significant advantage over fuses in that they can be reset after
tripping. They can also be used as the main ON/OFF switch for the equipment being protected.
Typical Applications Include:
ŠŠ Household Appliances
ŠŠ Transportation
ŠŠ Marine
ŠŠ Power Strips
ŠŠ Medical Equipment
ŠŠ Audio Visual Equipment
ŠŠ Power Supplies
ŠŠ Exercise Equipment
ŠŠ Among Others

C1005B-Series - Introduction
C1005B-Series
THERMAL CIRCUIT PROTECTORS
The C1005B-Series offers the functionality of a switch and
circuit breaker in a single compact package, which fits an
industry standard. 500 x 1.125 mounting hole. This combo
device eliminates the need for both a switch and thermal
circuit protector on customer panels. By using only
this multipurpose product, wiring and assembly costs
are greatly reduced, while at the same time, valuable
panel real estate is saved.
The C1005B-Series is available lighted or unlighted, in
a variety of colors, with solder lug or .250 Tabs. Current
ratings range from 7-16 [email protected] and 250 VAC and
up to 32 VDC.
