Continuous load to be carried by the circuit breaker (no trip); mostly indicated on type label of motor etc.
Normally the mains voltage, e.g. 230VAC world wide or 115VAC for North America. Rated voltage means the voltage value indicated with plus and minus tolerances.
Number of phases / protected phases. With DC normally one phase, i.e. 1-pole or 2-pole if both - line and return line - shall be protected.
threadneck:
single hole or panel mounting with hexnuts and knurled nuts
flange:
snap-in panel mounting
front panel:
panel mounting or screw-in mounting
plug-in type:
plug-in mounting into a socket (normally with P10 blade terminals / quick connect)
printed circuit board:
to be soldered on pc boards
integral:
device to be inserted into a given form
blade terminals / quick connect:
plug-in blades 6.3mm, 4.8mm or 2.8 mm
screw terminals:
for clamping the connecting cables
solder terminals:
for solder connection of connecting cables
Signal contacts for signalling that the circuit breaker has tripped
rocker:
rocker switch for ON/OFF operation
toggle:
toggle switch for ON/OFF operation
push button:
button to switch ON or - with some breakers - to switch ON or OFF (push/push or push/pull)
manual release button:
additional button to switch off the breaker mechanically
thermal:
thermally (normally by means of a bimetal) delayed trip
thermal-magnetic:
thermally delayed trip with low overcurrents, instantaneous magnetic trip with high overcurrents or short circuit
hydraulic-magnetic:
hydraulically delayed magnetic trip (HM = hydraulic-magnetic) or instantaneous magnetic trip (MO = magnetic only)
high performance:
thermal or thermal-magnetic trip for high short circuit values and high shock and vibration values.
