CBE, 2 Pole Sensing, 2 Pole Switching, 3120 Series
IEC Classification S/TO (with modules, S/TM). This range of 2 pole sensing thermal switch and circuit breaker offer enhance protection over single pole devices with the added benefit of not being 'polarity' sensitive for wiring purposes. Basic tripping time at 2xI N, 20-30 second. These units may also be used with the magnetic conversion module in this range, to convert the breaker to a thermal/magnetic type, for closer protection against short circuits. Circuit protection designed for equipment, sub-systems and components.

Depth behind panel: 43mm


Термомагнитные, обратимые Thermal Magnetic Convertible
All CBEs have blade terminals and have an insulation resistance greater than 100MΩ (MegaOhms).

IEC 934 (BS/EN 60 934) definitions
IEC requirements to equipment over-current contact breakers, in which complete short circuit either cannot occur or is limited by back-up protection somewhere else in the system.
Equipment contact breakers are divided into three main types:
RS type - that automatically switches off if there are overloads that require manual reset.
M type - functions as above, but can occasionally be used for manual shut down; is however not intended to function as a normal switch in daily use.
S type - combines overload protection with the opportunity for use as a normal on/off switch under normal load conditions.
Each of the above types has a sub-set with the following trigger methods:
TO - Thermal only. Sensitive to the heating effect of an over-current, because it uses a bi-metal or similar element as a contact breaker.
TM - Thermo-magnetic. A magnetic solenoid in series with a thermal element provides a more rapid response to a large fault current.
MO - Magnetic only. Triggers immediately when an overload is registered.
HM - Hydraulically dampened magnetic. Provides a long range of characteristics for delayed triggering and is mainly insensitive to changes in ambient temperature.
EH - Electronic hybrid. Combines solid state registration of overloads with physical circuit breaking.
