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. DIMENSIONS R 20 / R 22 / R 40 R 30 / R 32 Bimetal Cutouts Temperature Regulators Temperature Limiters ADVANTAGES R 20 – high pressure resistance R 22 – high response sensitivity R 30 – numerous applications R 32 – various housings, connections and mounting styles R 40 Types: R20/22/30/32/40 03-03-00 1000-Y135 mounting flange rotating 360 degress mounting flange rotating 360 degress Standard version Standard version CANTHERM

Temperature regulation, temperature monitoring, temperature limiting and indication in electric appliances and industrial equipment, machinery and process engineering. Examples: Vacuum cleaners Electrical house- Ironing machines hold appliances Cooking equipment Electronic circuits Dampers Machinery Heat radiators Process engineering Hot water heaters Industrial electric Coffee machines elements Egg boilers Electrical components Electric appliances RESET TEMPERATURES Reset temperature will be between 5 °C and 50 °C below the standard response temperatures. 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 ensu- res that time delays of thermal control systems are kept very small: insensitive to installation posi- tion. 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 respec- tively the mounting bracket should be soldered, rivetted, screwed or spot-welded to the heat source. RESPONSE TEMPERATURE, TOLERANCE, CODE-NO.

SPECIAL TEMPERATURE SETTINGS Response temperatures and reset temperatures with specific values and alternative tolerance can be supplied. SPECIAL CONNECTIONS Leads or solid wire from 0.25 mm 2 to 1.0 mm2. Lengths from 40 mm to 10 000 mm, with or without stripping possible. Lead ends with DIN connectors or shrouds. Freon and oil resistant leads, PTFE-, PVF 2, Nomex and Silicone leads available from stock. SPECIAL HOUSINGS When selecting the switch-off temperatures of ther- mostats in special housings or with non-standard mounting, the time delay due to the thermal mass of the housing/mounting has to be considered. Closer tolerances of nominal switch-off temperatu- res and reset temperatures, as well as small diffe- rentials, are also available for small quantities on request.
