Sonel MZC-310S

Product ID: 19161

• Measurement of very low short circuit loop impedances (with resolution 0,1 mΩ) with a current of 150 A at 230 V; maximum 280 A at 440 V.
• Measurement with a current of 23 A at 230 V, maximum 42 A at 440 V with resolution 0,01 Ω.
• Measurements in installations with rated voltages: 220/380 V and 230/400 V and frequencies 45…65 Hz.
• Ability to perform measurements in short circuit system: phase-phase, phase-PE, phase-N.
• Differentiation between the phase voltage and the inter-phase voltage while calculating the short circuit current.
• Ability to change the length of test lead (measurement with 2p method).
• 4p (four-pole) method, test leads do not require calibration (measurement with current up to 280 A).
• Measurement of resistance (R_S) and reactance (X_S) components.

The Sonel MZC-310S is a high-precision tool for testing the impedance of short circuit loops in consumer networks as well as in distribution networks protected with high-current circuit breakers. The meter evaluates both the impedance and shock/contact voltages while using the four-wire method, allowing it to determine whether or not the circuit breakers are working properly. Due to its versatility, this single device is well suited for use by many different professionals. The meter complies with EN 61557 standards.
