Eaton xEnergy Molded Case Circuit Breaker 1-Pole 250A, Breaking Capacity 50 kA, Fixed Mount 690V AC 750V DC 259094 NZMN2-A250

The Eaton 259094 NZMN2-A250 xEnergy Molded Case Circuit Breaker (MCCB) delivers robust protection for electrical installations, combining a 1-pole, 250A current rating with an industry-leading breaking capacity of 50 kA. Engineered to stringent EN/IEC standards, this fixed mount MCCB is designed for demanding industrial, manufacturing, and commercial applications requiring reliable protection against short circuits and overloads.

Operating at rated voltages of 690V AC and 750V DC, this circuit breaker supports a wide range of electrical systems. Its compact dimensions of 195mm height, 184mm width, and 149mm depth make it ideal for confined switchgear setups. The MCCB employs a thermal magnetic tripping mechanism that guarantees fast and precise interruption, protecting sensitive equipment from fault currents.

The toggle switch reset actuator offers straightforward operation, while screw terminals ensure a secure electrical connection, minimizing downtime during installation or maintenance. With an instantaneous break time and a robust IP20 rating, the breaker is safeguarded against accidental contacts and ingress of objects larger than 12 mm.

Operating reliably in temperatures from -25°C to +70°C, the Eaton MCCB suits diverse industrial settings including automotive workshops, factories, and processing plants. It is especially suitable where high breaking capacity is critical to maintaining operational safety.

Rated for high AC and DC voltages of 690V AC and 750V DC respectively. Implements thermal magnetic tripping for effective overload and short circuit protection. Compact fixed mount design fits easily into crowded electrical panels.

Instantaneous break time for rapid disconnection during faults. Screw terminal type enhances installation convenience and reliability. IP20 rating ensures protection from accidental contact and solids over 12mm in size. Wide temperature range operation supports various industrial environments.

Complies with EN/IEC standards ensuring global regulatory acceptance.

This MCCB is an essential component in industrial and commercial electrical safety systems, protecting motors, control gear, and automation installations against electrical faults.
