CIRCUIT BREAKERS FOR EQUIPMENT

Product description

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 tempe-

rature 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 re-

close 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 devi-

ces of the building installation.

The TS-Line is designed for automatic interruption and non-automatic

(manual) resetting only (R-type CBEs). They utilize a reliable snap-

action bimetal to achieve the automatic opening operation and quick

connect terminals for easy connection.

Common features are:

TS-LINE

Attractive prices

Wide range of ratings

Reliable design

Approvals

The TS-701 line has a threaded neck for panel mounting. The overall

dimensions are slightly bigger, but the available ratings are

considerably higher (up to 40 A).

The TS-709 line is a push to reset type CBE for panel mounting

(threaded neck). Its strong points are the small size and the attractive

price. Rated current are from 3A to 16A.

The TS-710 line fits into the mounting cut-off of miniature fuseholders.

Where the advantage of having a reusable protective device counts,

this CBE has its application.
