MCCB 1P Thermal Magnetic 80A, 30KA 4125V
The MCCB 1P Thermal Magnetic 80A, 30KA 4125V (SKU: NM8-250S-1P-80A-KIT) is a robust single-pole moulded case circuit breaker designed to provide dependable overload and short-circuit protection in low-voltage electrical systems. It is suitable for use in commercial, industrial, and larger residential power distribution environments where safety and reliability are essential.
Manufactured to CHINT’s recognised quality standards, this thermal-magnetic circuit breaker offers a strong breaking capacity of 30kA at 415V, ensuring effective protection against high fault currents. Its compact form makes it ideal for installation in distribution boards, control panels, and electrical enclosures where space may be limited, without compromising on performance.
The thermal-magnetic protection mechanism allows the breaker to respond gradually to overload conditions and instantly to short circuits. This helps prevent unnecessary tripping while still protecting connected equipment from electrical damage. With a rated current of 80 amps, it is well suited to medium-load applications such as motors, compressors, lighting circuits, and general power distribution.
The single-pole configuration makes this MCCB a practical choice for specific circuit protection requirements, especially in installations where individual line control is needed. Its durable construction supports long-term use in demanding environments, giving installers confidence in both performance and safety.
Whether you are upgrading an existing electrical panel or specifying protection for a new installation, the NM8-250S-1P-80A-KIT provides a reliable and cost-effective solution for managing electrical faults and maintaining safe power distribution.
