FuseBox TPN 100A 4P Mains Switch

The CHINT IT1004 is a robust 100A 4-pole main switch (switch disconnector) designed for safe isolation and control of three-phase low-voltage electrical distribution systems with neutral switching. It is widely used as an incoming isolator in distribution boards, providing complete disconnection of all live conductors for maintenance, safety, and system control.

With its 4-pole configuration (L1, L2, L3 + Neutral switching), the IT1004 ensures full electrical isolation of the supply, making it suitable for installations where neutral disconnection is required for safety compliance or system design. It is commonly used in commercial buildings, industrial panels, and three-phase consumer units as the main isolating device before downstream protection such as MCBs, RCBOs, or MCCBs.

The device is rated for 100A continuous current and designed for AC-22A utilization category, meaning it is suitable for switching mixed resistive and inductive loads commonly found in general power distribution systems. Its durable internal mechanism ensures reliable switching performance, long service life, and safe operation under normal load conditions.

The IT1004 is designed for DIN rail mounting, allowing quick and standardised installation in modern distribution boards. Its clear ON/OFF indication and ergonomic switching handle provide safe and intuitive operation during maintenance or emergency isolation.
