 Open Frame Thermostats    PDF

A10, A20, A30, A40
These thermostats are specificaly designed for electrical appliances, such as hair dryers, hairdressing equipment, cooking equipment, air heaters. These are factory calibrated bimetals to snap open at a predetermined temperature. Reset is preceeded by significant cooling.

Applications Household appliances, Electronics, Fan Heaters, Automotive Industry

Benefits More safety by self hold types, PCB terminals available, Customized ratings, Up to 100,000 cycles

1) For current-time based types (execution D, J, K, L, M, P, R, V) the following information must be provided:


• DC or AC voltage UN in Volts.

• Continuous operating current Ic in Amps at which the switch must not respond.

• Current level I0 in Amps at which the switch must respond.

• Response time t0 (in seconds ± tolerance) within which the switch must respond after reaching I0.

Ambient temperatures which could be experienced both in normal operation and in switching conditions.

• Maximum current in Amps.

------

For special applications version P is available with a very low self heating rate.

Version A10H is VDE approved with 100,000 cycles at 1 Amp and 30,000 cycles at 10 Amps also.

Manual reset: The maximum operating force must not exceed 6 N. The control should not be reset before the starting conditions are reached, meaning there should be a satisfactory cooling down time!
