DITEK DTK-120SLR Surge Protective Device with Load Removal

Protect mission-critical security, fire alarm and surveillance power circuits with the DITEK DTK-120SLR surge protective device. This purpose-built surge protection module delivers fast, series-connected suppression for 120V AC single-phase circuits (up to 20 A), helping prevent damage to fire panels, gate motors, access control and monitoring equipment. The DTK-120SLR goes beyond clamping — its load-removal feature disconnects power to equipment if the SPD is compromised, preventing cascading failures and reducing replacement costs.

Engineered by DITEK, the unit includes UL1283 EMI/RFI noise filtering to maintain clean power for cameras, recorders and sensitive electronics, while front-panel diagnostic LEDs give clear, immediate status for easy onsite troubleshooting. TAA and NDAA compliance, RoHS certification, and US manufacturing make this an ideal choice for commercial and government installations.

Specify the DTK-120SLR for projects where uptime and equipment protection matter. Ideal for security, surveillance and monitoring applications — contact your distributor or add to your next system design to safeguard critical infrastructure.
