MT312 RCD/ELCB, Loop & Polarity Tester
The MT312 is a compact and reliable tester designed for quick verification of 3-wire AC circuits. Ideal for electricians and technicians, it combines RCD/ELCB testing, loop impedance measurement, and polarity verification in one easy-to-use unit.
With clear LED and LCD indicators, the MT312 instantly displays wiring status, voltage readings, and loop resistance levels—helping you identify faults fast. It also features a Non-Contact Voltage (NCV) function for safe voltage detection without direct contact.
Perform tests directly at a power outlet or switchboard (optional MT350L lead available), and get instant feedback with color-coded LED indicators for wiring conditions:
-
Green – Good: Resistance < 1.8 Ω
-
Orange – Check: Resistance between 1.8 Ω & 92 Ω
-
Red – Urgent Check: Resistance > 92 Ω
Other features include a fault trip time of up to 99.9 ms and a 10-second buzzer alert during ELCB trips, plus automatic loop impedance testing for accurate results every time.
Key Features:
-
Tests RCD/ELCB, loop impedance, and polarity
-
Non-contact voltage detection for safety
-
LED & LCD display for clear, instant readings
-
Direct voltage measurement (Live-Neutral / Neutral-Earth)
-
Automatic loop impedance testing
-
Optional MT350L lead for switchboard testing
