The Ditek DTK-120/240HD is a heavy-duty 120/240V split-phase surge protective device (SPD). First, it wires across the protected panel as a 3-wire plus ground (3W+G) install. Then it shunts transient voltages safely to ground.
Specifically, the DTK-120/240HD carries a 50,000 A per-phase Maximum Surge Current rating. In addition, each protected mode is individually fused for maximum reliability. As a result, a single catastrophic surge event will not take the entire device offline.
Where the Ditek DTK-120/240HD fits
The DTK-120/240HD is sized for residential and light-commercial service panels. For example, the compact form factor mounts close to the main panel for the shortest possible lead lengths. However, lead length still matters. Therefore, follow Ditek’s installation instructions to keep leads short and twisted.
Verified specifications
First, the device protects 120/240 V split-phase AC power systems. Then protection covers Line-to-Neutral, Line-to-Ground, and Neutral-to-Ground modes. In addition, diagnostic LEDs indicate both system power presence and SPD active status. As a result, technicians see at a glance whether the device has done its job.
Listings and warranty
The DTK-120/240HD is built for UL 96A Lightning Protection installation compliance. In addition, Ditek provides a 5 Year Warranty plus a $10,000 Residential Connected Equipment Warranty. However, the connected-equipment warranty has residential-install conditions that must be met. Therefore, review the warranty terms before claim.
