SU202MK50 2 Pole Miniature Circuit Breaker 50A K Type Reliable Protection for Motor Circuits

Miniature Circuit Breaker SU202MK50 number 10175829 Overview A compact two pole miniature circuit breaker intended for overcurrent interruption in AC distribution systems. The SU202MK50 combines a K tripping characteristic with a 50 amp rated current and a 15 kiloampere breaking capacity for reliable interruption of overloads and short circuits in common electrical installations. Key benefits Reliable circuit interruption: Automatically interrupts excessive current to limit damage to wiring and downstream equipment. Handles inrush currents: K tripping characteristic is suitable for circuits with moderate to inrush, such as motors and transformers, reducing unwanted nuisance trips. shortcircuit capability: 15 kA breaking capacity provides capacity to clear substantial fault currents in typical residential and commercial distribution networks. Compact, panelfriendly form: Two pole design conserves DIN rail and panel space while providing combined phase and neutral protection in single phase systems or twophase protection in multiphase setups. Clear specification for system matching: Rated for 50 A at 230/400 VAC so it can be selected with confidence for compatible circuits. Key specifications Model: SU202MK50 Poles: 2P Rated current: 50 A Tripping characteristic: K Breaking capacity: 15 kA (15,000 A) Rated voltage: 230/400 VAC number: 10175829 Function and performance This device is designed to detect and interrupt excessive current flows caused by overloads or short circuits. The thermalmagnetic tripping with K characteristic provides a higher instantaneous trip threshold to tolerate inrush currents while still interrupting faults quickly. The 15 kA interrupting rating indicates the maximum shortcircuit current the device can safely open at the rated voltage. Compatibility and installation notes Suitable for use in 230 VAC singlephase and 400 VAC threephase distribution systems when arranged appropriately. Two pole configuration provides combined phase and neutral disconnection where required by the installation. Compact design fits standard panel and distribution board layouts; verify mechanical dimensions and mounting type with your panel specifications prior to installation. Typical applications Small commercial and industrial motor control circuits where moderate inrush currents occur during motor startup. Distribution protection for lighting and receptacle circuits in residential and commercial buildings at up to 50 A. Protection for transformerfed subcircuits or equipment with occasional inrush, where a K characteristic reduces nuisance tripping. Ordering information Model SU202MK50, number 10175829. Confirm compatibility with system voltage, required pole count, and upstream protective coordination before selection.
