قطع‌کن مدار MCCB WLM8EY-250H-3300 با ولتاژ 250 آمپر، 3 پین، نوع LCD الکترونیکی

One of the main features of MCCBs is their ability to protect personnel from indirect contact, making them an important component in ensuring the safety of operating electrical systems. Additionally, MCCBs provide protection against long-term ground faults that cannot be detected by overcurrent protection, thereby reducing the risk of fire and ensuring the overall safety of the electrical system.
