MTL TP48 Surge Protection for 2, 3 & 4 Wire Transmitters

The Crouse-Hinds series MTL TP48 surge protection device safeguards field-mounted process transmitters where it matters, right at the unit. After a simple installation (the TP48 screws into an unused conduit entry, with no additional modification), it provides high-level protection against surges and transients while normal operation remains unaffected.

The TP48 resets itself automatically after each operation. The device is available with screw threads to suit different transmitters, with explosion-proof and intrinsically safe options for hazardous areas. Working voltage is 48V dc maximum with impulse ratings of 10kA peak current and 10kV peak voltage.
