Kyoritsu 4118A LOOP/PFC/PSC Tester

Key Features:

  1. Loop Impedance Testing – Measures the impedance of the earth fault loop, ensuring that the circuit protection device will operate correctly in case of a fault.
  2. PFC and PSC Testing – Measures the prospective fault current (PFC) and prospective short-circuit current (PSC) to verify that the protection system will function as intended during a fault.
  3. Advanced Fault Detection – Helps detect potential faults in electrical installations, ensuring that they can safely handle fault currents.
  4. Clear, Easy-to-Read Display – Features a large digital display that shows test results clearly, making it easier for electricians and technicians to interpret.
  5. One-Touch Testing – Simplifies the testing process with one-touch operation for quick and accurate readings.
  6. Auto-Ranging Function – Automatically adjusts the measurement range for greater accuracy and convenience.
  7. Compact and Portable Design – Lightweight and easy to carry, making it ideal for field testing and on-site inspections.
  8. Multiple Testing Modes – Offers various modes to test different parameters, such as loop impedance, PFC, and PSC, for a comprehensive evaluation of the electrical system.
  9. Safety Features – Designed with built-in protection to prevent errors and ensure safe testing.

Kyoritsu 4118A is a Loop/PFC/PSC Tester designed for measuring loop impedance, prospective fault current (PFC), and prospective short-circuit current (PSC) in electrical systems.
