Tmax XT Compact Circuit Breakers – Reliable Installation Protection

The Tmax XT3N 250 TMD 250-2500 3p F F compact circuit breaker is an advanced solution for protecting electrical installations. Manufactured by ABB, this device combines high protection efficiency with a compact design, making it an ideal choice for both professional installers and end-users. The three-pole design provides comprehensive protection against overloads and short circuits in three-phase circuits.

This circuit breaker is equipped with a thermal-magnetic trip unit (TMD), which ensures precise and reliable response to various network disturbances. The TMD trip unit allows you to adjust the tripping characteristics to the specifics of the protected circuit, minimizing the risk of unnecessary tripping. The rated continuous current of 250A and the short-circuit breaking capacity of up to 36kA at 400V AC guarantee effective protection even in demanding operating conditions.

• Versatile application: ideal for power distribution in commercial buildings, industrial plants and critical infrastructure.
• High reliability: the TMD thermal-magnetic trip unit ensures precise and stable operation in various conditions.
• Compact design: facilitates installation and integration with existing electrical installations, saving valuable space in the switchboard.
• Configuration flexibility: the ability to mount a motor drive allows for remote control of the circuit breaker and integration with building automation systems.
• Safety of use: compliance with IEC/EN 60947-2 standards ensures a high level of safety and reliability.

The XT3N 250 TMD circuit breaker has bolted connections, which facilitates quick and secure cable installation. The IP20 degree of protection provides protection against accidental contact and the ingress of solid objects larger than 12mm. Power losses of 17.8W minimize the impact on the energy efficiency of the installation. The device is designed for stationary mounting and does not require additional mounting elements for TH or DIN TH busbars. The rated operating voltage of up to 690V AC expands the range of applications for the circuit breaker, allowing its use in various electrical installations with high rated voltage.
