Three-phase three-wire systems can only provide a 380V voltage power supply. In contrast, three-phase four-wire systems can provide both 380V and 220V voltage power supplies. Three-phase three-wire systems cannot pass zero phase feedback current when the load is unbalanced, which can lead to the load burning out. However, three-phase four-wire systems can solve this issue.
A 3-Phase 4-wire system can provide both 380V voltage and 220V voltage. It solves the problem of not being able to pass zero phase feedback current when the load is unbalanced, which is a common issue with 3-Phase 3-wire systems. This prevents the load from burning.
It has been demonstrated [6,10] that for three-phase three wire electrical systems, both the American and the European approaches produce the same value in the calculation of apparent power. Thus, this paper focuses on three-phase four wire systems. D. Sreenivasarao, ... Biswarup Das, in Electric Power Systems Research, 2012
Safety and Efficiency: In three-phase systems, a four-wire configuration allows for the use of smaller, more cost-effective wiring while supporting the ability to transport more power efficiently, compared to single-phase systems.
No Neutral Wire: The absence of a neutral wire means the system is dedicated solely to three-phase equipment. High Efficiency: These systems are highly efficient for large industrial loads, especially where the power is symmetrically balanced across all phases. Voltage Configurations: Equipment typically runs on a 400V three-phase system.
The three-phase loads are balanced and do not contribute to neutral current therefore the neutral conductor can be removed. However, balancing of load on every phase is difficult in the case of single-phase loads. Due to this imbalance, some neutral current always flows. Therefore, the neutral wire is very essential in this case.

When the neutral wire in a 3-phase, 4-wire system is disconnected, the loads that are connected between any two line conductors and the neutral are get connected in series and the potential difference across the combined load becomes equal to the line voltage. The potential difference across each load is changed according to the rating of the load.
