ABB Molded Case Circuit Breaker 4-Pole 200A Thermal Magnetic 65kA Breaking Capacity 690V AC Fixed Mount XT4N

ABB XT4N Molded Case Circuit Breaker, model XT4N, is a 4-pole device rated for 200A current and a breaking capacity of 65kA, designed for reliable overload and short-circuit protection in industrial electrical systems. It operates with a thermal magnetic tripping mechanism suitable for handling sustained overloads and instantaneous faults. The circuit breaker is intended for fixed mounting and is equipped with fixed terminals for secure connections in distribution panels, offering dependable protection for three-phase plus neutral configurations.

Engineered to operate in high voltage applications, it supports rated AC voltage up to 690V and DC voltage up to 500V, ensuring versatility for various electrical installations. The reset lever actuator facilitates quick manual reclosure after a trip event, improving operational efficiency while maintaining safety.

This breaker’s compact physical footprint - 140mm width, 160mm height, and 82.5mm depth - makes it suitable for integration into standard panels and switchgear configurations. Compliance with CE and IEC standards along with RoHS adherence ensures international safety and environmental requirements are met. The high breaking capacity of 65kA minimizes the risk presented by high fault currents, enhancing system protection.

Typical applications include protection of motor control centres in manufacturing environments, safeguarding switchboards in automation systems, and use with battery-inverter arrays requiring DC disconnection capability. It is also suitable for distribution feeders in commercial electrical installations and protects three-phase equipment that includes neutral conductors.

Rated 200A current rating for robust overload protection. Thermal magnetic trip mechanism ensures dual protection against overload and short circuits. Fixed mounting and terminal types simplify installation and panel conformity.
