Description
C Series thermal protectors are highly efficient miniaturized bimetal switches made to protect electrical equipment (electric motors, transformers, electronic boards, etc.) against abnormal temperature rises. The C Series (C1, C4, C8), due to the combination of the materials used for the contacts with the type of bimetal chosen, is suitable for any application where temperature control is needed.
The bimetallic disk used for models C1 and C8 is sensitive to current overloads and reacts extremely quickly, while model C4 has low current sensitivity.
MAGNETIC AND MECHANICAL PROTECTION The C-Series housing is constructed of steel-nickel to ensure resistance to mechanical pressure in excess of 600 N. The housing also allows the thermostat to be insensitive to magnetic fields, this prevents spark deflection.
TERMINALS Terminals, whose dimensions (section and length) do not directly affect those of the thermostat, are placed on the front side to prevent damage during head forming.Terminals can be supplied to customer specifications.
CONSTANT RESISTANCE OF CONTACTS The resistance of contacts is ensured by the selection of materials used and the high clamping pressure.The behavior of the C series is constant over time.
IMMEDIATE SHUT-DOWN The switching times are particularly short as a function of the high sensitivity of the bimetal.
CABLES Cables are supplied according to customer specification.
PATENTED DESIGN
AUTOMATIC PRODUCTION The production of thermostats is fully automated and is inspected at 100%.
APPROVALS C-series thermostats are VDE, UL and CCC approved.
THERMAL RESPONSE The thermal characteristics of the C-series are further accentuated by the type of current-sensitive bimetal that is used to provide even greater protection against current surges.
PIN VERSIONS For applications on electronic boards, the protectors are made with a metal housing covered with a plastic film, and PIN terminals are used for the electrical connection.
