Product Description:
The CHINT NXM-250S/4300 200A MCCB (4-Pole) is a heavy-duty molded case circuit breaker designed to safeguard three-phase + neutral (4P) electrical systems from overloads and short circuits. With a rated current of 200A and a breaking capacity of 36kA at 400V, it is ideal for industrial control panels, commercial distribution boards, and infrastructure projects requiring reliable, high-capacity protection.

Its fixed thermal-magnetic trip unit ensures consistent fault detection, while the 4-pole configuration enables full isolation of all live conductors — including the neutral. Housed in a compact NXM-250 frame, it meets international electrical safety standards.
