|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.
