Temperature switch TSA-Atex, TOA-Atex series

• ATEX application Zone 1 (cat. 2G), intrinsically safe as per EN 60079-11
• Simple, robust design
• Electrical inner part, easy to remove
• Cable outlet direction adjustable in 90° steps for DIN connector
• Elastic sealing ring

When applying switch points below 50°C / 122 °F it must be observed that there is a sufficient temperature difference between the system and ambient temperature because otherwise the reset point cannot be reached reliably. The TSA-Atex series consists of simple electrical equipment without a separate voltage source. In the case of intrinsically safe connections as per EN 60079-11, the TSA-Atex can be used in Zone 1 (group IIC, device category 2G) explosive areas; this also applies to the inner zone of the tank. The temperature switches are classified into temperature class T4. The design of the temperature switch was chosen, to enable the removal of the electrical inner workings without having to remove the switching tube from the tank. This is convenient if the temperature switch is installed externally underneath oil.
