B. Matrix. A semiconductive polymer core whose
electrical resistance varies with temperature.
When process temperature drops, the core’s
heat output increases; conversely, as process
temperature rises, heat output decreases.

Circuit Breaker Selection
Circuit breakers must have sufficient capacity to allow
for the inrush current of initial start-up. To determine
the circuit breaker size required, multiply the start-up
in amps/ft. times the installed total cable length in feet
at the expected start-up temperature (°F).
NOTE: Thermal circuit breakers are recommended
since magnetic circuit breakers could “nuisance trip”
at low temperature.
