CURRENT SENSITIVITY
The thermostats are not current sensitive at rated
currents. At loads above the rated values, upto
maximum loading there is self-heating of the cur-
rent-carrying contacts. If current sensitive cutouts
are required, please refer to the data sheet „Thermal
cutouts – current sensitive thermal protection for
coils/windings (Nr. 395).
INSULATION RESISTANCE
Housing (with insulation)
to earth
2750Veff. AC P 302
On request, in special housing,
upto
4000Veff. AC P 304
Across open contacts, dependent
on response temperature
500Veff. AC P304
Voltage of coil depending on application,
please ask.
CONNECTIONS
Flexible leads or solid wire in different lengths and
cross-sections are available – please ask.
RESPONSE TEMPERATURES, TOLERANCE
Temperature stepped in 5 °C intervals, and toleran-
ce in K from 50 °C to 160 °C. Special switch-off and
reset temperatures available on request.
Rate of temperature rise from 0.1 K/min. to max. 1.0
K/min.
Insulation of the housing will slow down the cutout’s
response.
Standard reset temperature between 5 K and 50 K,
depending on response temperature.
