DESCRIPTION
These directly heated thermistors have a positive
temperature coefficient and are primarily intended for
overload protection. They consist of a naked disc with two
tinned brass or copper clad steel leads and coated. Leadless
disks and leaded disks without coating are available on
request.

Notes
1. The thermistors are clamped at the seating plane.
2. Imax is the maximum overload current that may flow through the PTC when it passes from the low ohmic to the high ohmic state.
UL approval: Imax *0.85

Imax as stated in the Electrical data and ordering information tables, is the maximum overload current that may flow through the
PTC when passing from the low ohmic to high ohmic state at rated voltage.
When other voltages are present after tripping, the Imax value can be derived from the above Imax as a function of voltage graph.
Voltages below Vrated will allow higher overload currents to pass the PTC.
