Switch type thermal circuit breaker
16 - 40 A, 32 - 250 V | TS series
SCHURTER
The TS-line consists of a series of low cost thermally operated CBEs
available in three frame sizes for rated currents up to 40 A.
They are intended to provide protection against sustained overloads.
All CBEs of the TS-line use a thermo-bimetal to simulate the thermal
behavior of the protected components, which could be conductors in
wiring, motors, transformers etc.
The snap-action type of bimetal opens the contact when the temperature of the bimetal has reached a certain threshold level. The circuit
will then remain open unless the reset (or ON-) button is permanently
depressed. In this case the snap-action contact will momentarily reclose until the bimetal has reached its trip-temperature again and
effects the automatic opening operation. This behavior is termed
"cycling trip-free". The "cycling" indicates the momentary re-closings
which do occur, the "trip-free" indicates that the opening operation of
the contacts can not be prevented by pressing the ON or the RESET
button.
Every CBE of the TS-line can well cope with overload currents up to 6
times the rated currents without any back-up assistance. If the fault
current could be higher, CBEs require back-up protection. In many
instances, this back-up protection is provided by the protective devices of the building installation.
