DESCRIPTION
Types R 20/R 22/R 40 are bimetal detectors and temperature regu-
lators.
Types R 30/R 32 are temperature limiters (manual reset) without
tripfree mechanism.
The thermal response works via a bimetal snap element electrically
connected to the switch contact.
The switch system is current insensitive.
The thermal switches react only to external thermal effects. Double
contacts ensure high switch performance and long service life.
The housing, base, and the mounting brackets are voltage-free
(Standard version: base and mounting brackets are aluminium-plated
steel).
Heat transfer occurs directly through the metallic base via convection,
radiation and conduction in gaseous and solid media.
