Single Pair Protection Plug Without Test Access (IPM)

Product Code: 6905 2 604-01


Part No. : 6905 2 604-01                                                                                                                                                                                This provides both voltage and current protection for single pair on line side. The primary protection is built in by 3 pole GD Tube. The secondary over current protection is provided by Positive Thermal Coefficient.

Features:
• Mounts on Disconnection / Switching module
• Simple plug in operation along with Earth bar
• To protect Switching Equipment of Central office /DLC etc
• Overvoltage protection using 3 Pole GD Tube
• Overcurrent protection using PTC resistors
• Optional variants with test access contacts or overcurrent trip indicator
• Meets ITU recommendations
