Eaton MTL TP48 surge protector for field transmitters
MTL TP48 protects field-mounted transmitters from lightning surges: screws into a spare conduit entry, self-restoring, Ex ia/Ex d versions with ATEX, IECEx, FM, CSA.
- Easy installation into a spare conduit entry – no rewiring
- Self-restoring after every surge
- ½″ NPT, M20 ISO and G½″ BSP thread options
- Parallel connection adds no loop resistance
Overview
The MTL TP48 is a surge protector designed to protect field-mounted transmitters against surges caused by lightning or cable-induced transients. It screws directly into a spare conduit entry of the transmitter, needs no extra wiring and adds no resistance to the loop.
Key features
- Simple installation into a spare ½″ NPT, M20 ISO or G½″ BSP entry
- Self-restoring after each surge for continuous protection
- Intrinsically safe and flameproof versions certified to ATEX, IECEx, FM and CSA (IIC, T4–T6)
- Fieldbus compatible (FOUNDATION fieldbus, PROFIBUS PA), 1 MHz bandwidth
- 2-, 3- and 4-wire versions protecting +ve, –ve, signal and earth
- 10-year “No Fuss” warranty
Models
TP48-N / -I / -G (2-wire), TP48-3-… (3-wire), TP48-4-… (4-wire); NDI certified versions available for hazardous areas.
Applications
Oil & gas, refining and petrochemicals, power and renewables, chemicals, pulp & paper, marine, data centres and automation systems.
