Temperature Protection type TMA100Am
The temperature protection type TMA100Am is an intrinsically safe device designed to protect equipment against excessive temperature increase. It uses PTC temperature sensors built into the devices.
The temperature protection type TMA100Am is designed in accordance with the good engineering practice with respect to their safety and meet the requirements of the standards PN-EN 60079- 0 and PN-EN 60079-11.
The temperature protection type TMA100Am is designed to operate in an additional Exd rated flameproof enclosure or in a non-hazardous area, in an IP 54(65) rated enclosure, while the intrinsically safe circuits of the protection level can be used in hazardous areas at risk from gas and dust explosion.
