± 30% at 25°C; other tolerances available.

*High performance ceramic formulation, lower transition temperature provides reduced

power consumption for energy concious applications.

Note: All motor start pellets receive 100% resistance and 100% voltage pulse burn-in

simulating actual motor start-up.

Note: Selected pellets carry UL recognition per File E107611.

Note: Usage requires packaging materials appropriate for maximum pellet surface

temperature of 180

°C.

Motor Start Relays

Combination Assemblies

Vishay Cera-Mite offers a complete line of PTCR

motor start pellets designed for OEM pressure

contact mounting. Compressor and refrigerator

manufacturers, as well as selected HVAC after-

market distributors have chosen to design and

build their own proprietary motor start devices.

Such cost effective units allow for unique mounting

styles, special terminal arrangements, and

combination devices including start capacitors or

overload protectors.
