Listed to UL 1077, it serves as a branch-circuit-rated supplementary overcurrent device for control panels, HVAC equipment, and industrial machinery where the upstream feeder already provides main fault protection. The 15 A continuous rating at 277 VAC single-phase covers a 4.2 kVA resistive load at full line voltage. The K curve's 10–14× magnetic trip band means it holds through the inrush of a 15 A-rated contactor coil bank or a 150 VA control transformer; if your load is a motor starter with a 20× locked-rotor inrush, step up to a Z-curve or a dedicated motor-circuit protector. The 1-pole module occupies 17.5 mm of rail width — one TE (terminal width). Spring-cage terminals accept 0.5–25 mm² solid or stranded copper, with a strip length of 9–10 mm. The busbar comb can bridge adjacent S200 poles for common feed; verify the comb's current rating matches the 15 A load. In a multi-pole assembly, the S201-K15 snaps into the same rail profile as the S200 series, so a panel originally laid out for S201M-C10 accepts this K-curve variant with zero mechanical rework — just swap the module and confirm the trip curve matches the load. ## Compliance documentation Listed to UL 1077 (Supplemental Protectors) and CSA 22.2. The S200 series carries CE marking and is RoHS-compliant per EU Directive 2011/65/EU. REACH compliance documentation (SVHC declaration) is available from the manufacturer's technical support portal. No IEC 60898 or 60947-2 rating applies — this is a UL 1077 supplemental protector, not a full branch-circuit MCB; the distinction matters for panel SCCR calculations where the UL 508A supplement allows supplemental protectors only for specific component protection roles.","metaTitle":"S201-K15 ABB 1-pole K-curve 15 A 277 VAC 6 kA supplemental p","metaDescription":"ABB S201-K15 1-pole 15 A K-curve supplemental protector, 277 VAC, 6 kAIC, UL 1077.

The swap requires no mechanical rework — just verify the K curve (10–14× In) matches your load's inrush profile, since the S201M-C10 uses a C curve (5–10× In)."},{"question":"What compliance documentation does this brand provide for S201-K15?","answer":"UL 1077 listing and CSA 22.2 certification are on the nameplate.
