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. DIMENSIONS

APPLICATIONS Temperature monitoring, control and signalling in electronic and electrical equipment. Examples: Electronic components such as transistors, thyristors, diodes, triacs Power resistors Heat sinks Printed circuits Amplifiers Projectors Electrical machinery and apparatus Generating sets Heat exchangers Plastic and metal housings TECHNICAL DATA
Type Voltage rating* 50 - 60 Hz* Current rating cos = 1,0* Current rating cos = 0,6* Max. load at cos = 1,0 without damage E 05 / E23 250 V 2.0 A 1.2 A
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.

INSTALLATION HINTS 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.
