KEW 4140 Loop/PFC/PSC Tester
KYORITSU 4140 LOOP/PFC/PSC Tester
The KYORITSU 4140 LOOP/PFC/PSC tester is a precision instrument designed for measuring loop impedance, prospective fault current (PFC), and prospective short-circuit current (PSC) safely and accurately. The KYORITSU 4140 tester ensures reliable readings for electricians, engineers, and maintenance personnel in industrial, commercial, and residential electrical environments.
Key Features:
- Anti-Trip Technology: Ensures trip-free loop testing on RCDs rated 30mA and above.
- Dual Display: Enables simultaneous measurement of loop impedance and PFC/PSC.
- Two-wire Connection: Supports Loop L-L, L-N, and PSC testing.
- Additional Measurements: Phase rotation, voltage, and frequency measurements.
- Lock-Down Test Button: Facilitates 'hands-free' testing with auto-start operation.
- Backlit Display: Ensures visibility in dark environments.
- IP54 Rating: Water and dust-proof design for reliable field use.
