NSM Protector

Socket Outlet with integrated Surge Protection

For protecting electronic equipment against surges. Earthed socket outlet with surge protective circuit for installation in electrical installation systems. For installation in conformity with the lightning protection zone concept at the boundaries from 1 – 2 and higher. German utility patent.
  • Surge protection with monitoring device and disconnector
  • Enhanced safety due to fault-proof Y protective circuit
  • Visual operating state (green) and fault indication (red)
  • With retaining ring (diameter of 60 mm) for installation in switch boxes with a diameter of 60 mm and a depth of 40 mm

NSM Protector: Earthed socket outlet with integrated surge protection

Details

The devices of the NSM Protector family combine surge protection and earthed socket outlet in a single device. The two-pole surge arresters are specifically designed for protecting electronic loads in final circuits. Their very compact design incorporates the approved disconnector which disconnects overloaded surge arresters without interrupting the supply circuit. The low voltage protection level as well as the comprehensive protection against common-mode and differential-mode interference are typical of the devices of the NSM Protector family. The fault-proof Y protective circuit ensures safety even if the phase and neutral conductors in final circuits cannot be identified. The integrated disconnector ensures reliability of devices and installations. The standard green and red LEDs indicate the operating state of the surge protective devices.
