The Crouse-Hinds series MTL TP32 surge protection device is specifically designed to protect fieldbus transmitters and devices on fieldbus systems. The TP32 builds on the high specification of the acclaimed TP48 range to provide a level of surge protection for fieldbus transmitters in excess of the optional transient protection available from some transmitter manufacturers.
The TP32 protection network is a hybrid design consisting of high power, solid-state electronics and a gas discharge tube which is capable of diverting surges up to 20kA. Encased in a 316 stainless steel enclosure, the TP32 exhibits unparalleled mechanical durability.
The enclosure is available threaded for all common conduit entries and is designed to provide years of maintenance-free operation in harsh environments. Versions are offered for 1/2” NPT, 20mm ISO, and G 1/2” (BSP 1/2 inch) threaded entries.
The terminated TP32-T has the same protection circuit as the standard product, but also includes a Foundation Fieldbus H1/Profibus PA termination circuit. This unique combination eliminates the need to purchase and install additional termination circuitry for the fieldbus segment.
Approvals for intrinsically safe, flameproof, explosionproof and non-incendive operation are available, in all gas groups and apparatus temperature classifications up to T6.
