Industrial 2BU10 2 Pole DIN Rail Circuit Breaker

ALTECH ABL SURSUM 2BU10 is a two-pole DIN-rail mount circuit breaker designed for industrial control panels, delivering 10 A of nominal current per leg and mounting on standard 35 mm DIN rails with a 17.5 mm width per pole (35 mm total). The unit is intended for general-purpose AC protection in 50/60 Hz systems and is rated for up to 480Y/277 V AC, supporting typical industrial feeders and power‑supply circuits. It provides 10 kA short‑circuit withstand capacity, helping safeguard wiring and equipment from overload and fault conditions. Built for rugged environments, the 2BU10 belongs to the ALTECH ABL SURSUM family, a line of DIN-rail circuit breakers used to protect branch circuits on industrial machinery, panel assemblies, and automation equipment. This two-pole device offers compact yet reliable protection for dual‑circuit applications, enabling simultaneous isolation and protection of two lines in one enclosure. Its thermal‑magnetic operating mechanism delivers predictable tripping across a broad temperature range and 50/60 Hz operation, making it suitable for standard industrial power distribution and control panels.
