Why Choose the Chint NM8-125S-3P-20A MCCB?
The Chint NM8-125S-3P-20A is a reliable moulded case circuit breaker (MCCB) designed to protect low-voltage electrical circuits against overloads and short circuits. As part of the Chint NM8 series, it provides dependable circuit protection for commercial, industrial and panel-building applications where safe isolation and robust fault protection are required.
This MCCB features adjustable thermal magnetic protection, allowing the breaker to respond to overload conditions through its thermal element and short circuit faults through its magnetic trip mechanism. Its adjustable thermal setting helps engineers match protection more closely to cable ratings, connected equipment and installation requirements.
With a 20 A rated current, 3-pole configuration and 50 kA breaking capacity, the NM8-125S-3P-20A is suitable for three-phase distribution boards, machinery circuits, motor control panels and industrial electrical systems requiring compact and dependable MCCB protection.
