DITEK DTK-2MHLP75BWB — two-pair hybrid surge protection module for 75 V circuits, supplied with its single-position hardwired mounting base.
The module wires in series between the field wiring and the equipment, with unprotected and protected terminals on the snap-track base, so a strike on the loop is clamped before it reaches the panel. Because the suppression element plugs into that base, a module damaged by a surge is swapped without disturbing wiring.
- 75 VDC service voltage, 90 V MCOV, 108 V clamping voltage
- Two circuit pairs per module, differential and common mode
- 20,000 A surge current rating; 5 A max continuous current
- Hybrid TVS diode and gas discharge tube design; fails short to ground
- UL 497B certified; screw terminals take 30 to 12 AWG
- Minus 40°F to 158°F; 3.25 × 1.5 × 2.65 in. with the base
The suffixes matter. DTK-2MHLP75B is the same module with no base; DTK-2MHLP75FWB fails open circuit and is limited to 1 A rather than 5 A; DTK-2MHLP24BWB is the 24 V member. DTK-2MB through DTK-5MB replace the single base to protect four through ten pairs.

FAQ
What circuits is the DTK-2MHLP75BWB for?
DITEK specifies the 2MHLPxxBWB module for hardwired series installations on circuits from 5 to 75 V that operate at less than 5 A.
How is the module installed?
It wires in series through its mounting base, and DITEK requires the device to be installed and grounded by a licensed contractor per the applicable codes.
Can several modules share one base?
Yes. The base is available as a 1-up array (standard) or as 2- through 5-up arrays, and it can fit inside a 4 x 4 in. electrical box.
What if my circuit draws less than 1 A?
DITEK offers the 2MHLPxxFWB version for series circuits under 1 A.
