Thermal Cutouts Temperature Protection for Electronics ADVANTAGES – broad product range for many applications and loads – widest selection of connections and housings – minimal contact resistance E-Type DESCRIPTION Types E 05, E 11, E 15, E 16, E 18, E 21, E 22, E 23 and E 26 are thermal cutouts. Within limits they can also be used as temperature regulators. A bimetal snap disc with single or double contact opens or closes an electric circuit when reaching a pre-set temperature. Reset follows after a substantial drop in temperature. Heat transfer from all sides results from heat conduction or radiation onto the base of the housing. Standard version: aluminium, black anodised. 02-04-01 1000-Y133 DIMENSIONS E 05 (Standard) E 11 (Standard) E 18 (Standard) E 21 (Standard) CANTHERM 8415 Mountain Sights Avenue • Montreal (Quebec), H4P 2B8, Canada Tel: (514) 739-3274 • 1-800-561-7207 • Fax: (514) 739-290 E-mail : [email protected] • Website: www.cantherm.com APPLICATIONS Temperature monitoring, control and signalling in electronic and electrical equipment. RESPONSE TEMPERATURES When selecting the response temperature, the heating and cooling characteristics of the housing should be considered. Temperature testing is carried out with a rate of rise 0.1 °C/min. For cutout types E 05, E 11 and E 18 with response temperatures under 71 °C, the published electrical loading should be reduced by upto 50 %, as these types are current sensitive. Close tolerances on the response temperature or reset temperature, as well as smaller differentials are all possible on request. Reset differential as standard is between 10 °C and 50 °C. Minimum rate of temperature change 0.1 K/min.

It is important to ensure good heat transfer to the cutout: it should be placed directly onto the heat source. Housings are voltage-free (except G 800) and can be installed without additional insulation. The cutouts can be attached to metal surfaces or housings and, depending on the exact version, can be screwed, clipped, clamed or soldered on. G 800 version can be positioned direct onto a circuit board. 02-04-01 1000-Y133 INSTALLATION HINTS 02-04-01 1000-Y133 HOUSINGS Style Description G 254 E 18 Ø 16x5 G 700 E 05 SW10x3,7 G 701 E 05 G 702 E 05 Al black M4x6 Al black Ø 12x3,5 M4x6 CuZn threaded stud mounting threaded stud with solid wire leads E 11 Ø 16x4,8 M4x6 Al black G 707 E 11 Ø 15,7x4,4 M5x6 CuZn E 11 G 714 E 21 threaded stud mounting as E 05 G 800 however only 1 wire connection Ø 1.5 G 703 G 711 as E 18 but without mounting flange central fixing as G 703 but with leads SW12x4,8 M4x5 CuZn threaded stud as G 703 but with 2.8x0.5 tabs G 716 E 21 G 718 E 11 G 722 E 18 as E 18 but with narrow flange G 723 E 18 as E 18 but with 2.8x0.5 tabs G 724 E 18 as E 18 but with narrow flange and 2,8x0,5 tabs G 726 E 11 G 800 E 05 E 11 E 21 SW 16x4,8 Ø 16x4,8 M4x10 M4x6 Al black Al black threaded stud and leads threaded stud and leads tinned Cu lead wires SPECIAL CONNECTIONS Leads or single wire from 0,25 mm2 to 1,0 mm2, Lengths from 40 mm to 10 000 mm with or without stripped ends.
