The S273-K6A is a 3-pole unit (0.36 kg) while the S281-K50 is single-pole (0.14 kg). If the panel was wired for a 3-pole breaker, you cannot simply swap in a single-pole — the busbar and phase wiring differ. For a single-pole slot, the S281-K50 is a direct mechanical fit."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/abb/S281-K50","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/abb/S281-K50 when reusing this data.
