Schneider NG125 4P 125A 300MA AC 5.5-module differential lock 19042

VigiNG125 is an additional modular residual current device. It has 4P and current rating of 125 A. The earth leakage protection class is type A with a sensitivity of 300 mA and voltage-independent technology.

This product protects against short circuits, cable overloads, electric shocks from indirect contacts and fire hazards. This device is combined with an NG125 breaker to provide earth leakage protection and circuit protection. This product complies with IEC 60947-2.

The rated operating voltage Ue is between 230VAC and 415V AC. The rated insulation voltage Ui is 690V AC. The rated impulse withstand voltage Uimp is 8 kV. The pollution degree is 3. Can be mounted on 35 mm symmetrical DIN rail. Width in steps of 9 mm is 11.

Total dimensions are (H) 207 mm x (W) 118 mm x (D) 81 mm. The weight is 0.8 kg. The degree of protection is IP20 and IP40 in a cabinet.

The 'earth leakage circuit breaker is to protect people and not systems. The moment the person goes to touch it, it creates a circuit with the ground. The current instead of staying in the household circuit, uses the human body to go to ground.

The residual current device, also called a circuit breaker, is a device in your electrical system. It is capable of opening the circuit, that is, shutting off the power supply, the moment the current is accidentally lost.

A residual current circuit breaker offers protection in case of current leakage but not in case of overvoltage. Instead, the circuit breaker is required for this type of problem.

The AC type earth leakage circuit breaker, works only with alternating current. Almost all systems for civil use fall into this type.
