Ditek DTK-SL130B 130V 66 Block Surge Protection Module

Product Description

The DITEK DTK-SL130B is a single-pair surge protection module rated for 130 volts, designed for use on 66-style punch-down blocks in low-voltage data and voice wiring systems. The module provides transient overvoltage protection on a single twisted pair and includes an LED status indicator that allows technicians to confirm active protection at a glance without removing the module. This type of protector is installed by low-voltage technicians, structured cabling contractors, and telecom installers working on inside plant wiring. It carries a UL 497 listing, which covers surge protectors for communication circuits and is the applicable standard for this protection category.

The DTK-SL130B is suited for residential and light commercial applications where 66-block terminations are used for voice-grade or data-grade copper pairs. Typical installations include telephone distribution panels, PBX trunk lines, intercom systems, and other low-voltage communication circuits terminated on 66 IDC blocks. The LED indicator simplifies troubleshooting during routine inspections or after a surge event by providing a clear visual indication of module status without requiring a meter or additional test equipment.

Key Features

• Protects a single twisted pair at 130 volts nominal operating voltage
• Designed for direct installation on standard 66-style punch-down termination blocks
• Integrated LED status indicator confirms protection status visually
• UL 497 listed for surge protection on communication circuits
• Compact modular form factor allows replacement of individual pairs without disturbing adjacent terminations

Compatibility

Designed as an OEM-style replacement or new-installation surge protector for single-pair circuits terminated on 66-style IDC punch-down blocks in voice and data communication systems.

Installation Notes

Installation is typically performed by a licensed low-voltage or telecom technician in accordance with applicable NEC Article 800 requirements for communication circuits. De-energize or disconnect the circuit pair before seating or removing the module on the 66 block. Verify LED status after installation to confirm the module is functioning correctly. Follow the block manufacturer's guidelines for proper seating of modular protection devices to ensure solid IDC contact.
