Why Choose the ABB S202MT-B32UC Miniature Circuit Breaker?
The ABB S202MT-B32UC is a high-performance 2-pole miniature circuit breaker (MCB) designed to protect cables and electrical circuits against overloads and short circuits. Part of ABB’s S200MT UC range for traction and AC/DC applications, this breaker combines a 32 A rated current, Type B tripping characteristic and 10 kA short-circuit breaking capacity.
Designed for demanding rolling-stock, traction and industrial electrical systems, the S202MT-B32UC provides dependable protection for conductors and connected equipment. Its two protected poles allow coordinated circuit interruption, while the Type B characteristic is suited to circuits with relatively low inrush currents where responsive magnetic short-circuit protection is required.
ABB order code 2CDS272065R0325 identifies this exact S202MT-B32UC configuration. The breaker has a 440 V AC/DC rated operational voltage, supports conductor sizes up to 35 mm² and uses a compact two-module DIN-rail format for efficient integration into electrical distribution and control equipment.
