Trip Curve D means the magnetic trip threshold is set to 10–20 times the rated current (500–1000 A instantaneous). The 50 kA interrupting rating at 230 VAC tells you this breaker can safely clear a fault current up to 50,000 A without welding its contacts or rupturing the housing, which is essential for high-fault-capacity installations downstream of large transformers. The 2-pole configuration switches both line and neutral (or two phases in a split-phase system), giving full isolation on the protected circuit. The S800 series is ABB's high-performance MCB line, distinct from the S200 series by its higher interrupting capacity and wider operating voltage range. ## Deployment context The 2-pole footprint occupies two modular widths (36 mm typical per pole on the S800 series). Wire termination uses tunnel-type terminals accepting up to 35 mm² conductor — verify lug or ferrule size against your cable before terminating.","metaTitle":"S802S-D50 ABB High Perf MCB, 2P, 50A Curve D, 50kA","metaDescription":"ABB S802S-D50 high performance miniature circuit breaker, 2-pole, 50 A, Trip Curve D, 50 kA interrupting capacity at 230 VAC.
