DITEK DTK-120/240HD, 120/240VAC Split Phase Surge Protective Device

Protect critical power for security and IT systems with the DITEK DTK-120/240HD, a purpose-built 120/240VAC split-phase surge protective device. Designed for residential and light-commercial electrical panels, this DITEK surge protector delivers high-capacity protection — rated for 50,000 amps per phase — to safeguard surveillance cameras, access control, monitoring equipment, and network hardware from damaging transients and lightning-induced surges. The compact footprint lets you mount the SPD close to the panel, reducing lead length and improving performance while simplifying installation for integrators and electricians. Individually fused components isolate faults to prevent cascading failures and limit service interruptions, and an easy-to-read diagnostic LED provides immediate status for quick troubleshooting. UL96A lightning protection compliance, TAA/NDAA conformance, US manufacturing, and RoHS certification give procurement teams the compliance and reliability they require. Backed by a 5-year $10,000 residential connected equipment warranty plus a 10-year limited warranty, the DTK-120/240HD is ideal for protecting security, surveillance, monitoring, and networking infrastructure. Add this SPD to your panel to reduce equipment replacement costs and maintain continuous operation — contact us or order now to protect your system.
