Bimetal Cutouts Temperature Regulators Temperature Limiters ADVANTAGES – high pressure resistance – high response sensitivity – numerous applications – various housings, connections and mounting styles R 20 R 22 R 30 R 32 R 40 DESCRIPTION Types R 20/R 22/R 40 are bimetal detectors and temperature regulators. 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.

AREAS OF APPLICATION Temperature regulation, temperature monitoring, temperature limiting and indication in electric appliances and industrial equipment, machinery and process engineering. Examples: Vacuum cleaners Ironing machines Cooking equipment Dampers Heat radiators Hot water heaters Coffee machines Egg boilers Electric appliances INSTALLATION/MOUNTING INFORMATION Incorporation of the thermo-switch directly in the heat source or attachment to it, is possible without additional insulation. Slightest changes in temperature are conducted through the metallic housing cap directly to the bimetal snap disc of the thermo-switch. This ensures that time delays of thermal control systems are kept very small: insensitive to installation position. The dust-proof and damp-proof construction of the thermo-switch allows various methods of attachment to, and incorporation in appliances. To ensure the best heat transition, the cap respectively the mounting bracket should be soldered, rivetted, screwed or spot-welded to the heat source.
