Overview
The ABB S282-K6 is a compact miniature circuit breaker engineered for overcurrent protection in industrial and commercial electrical systems. Rated at 6A, 2-pole configuration, this breaker delivers current-limiting protection and thermal-magnetic trip characteristics ideal for machinery control, panel protection, and general-purpose branch circuit applications.
Key Features
- 2-pole, 6A rated current with K trip curve for motor and general load protection
- Rated voltage: 480VAC (277V/480VAC compatibility)
- Current-limiting design reduces fault energy and arc duration
- Fixed thermal and magnetic trip units for reliable instantaneous response to overcurrent conditions
- DIN rail mounting (35 mm standard) for panel integration
- Finger-safe screw terminals for safe connections

Typical Applications
The ABB S282-K6 is commonly deployed in:
- Motor control centers and variable frequency drive (VFD) circuits
- Industrial machinery and equipment branch circuit protection
- Control panels and PLC input/output module power supplies
- Supplemental protection for sensitive electronic loads
- Commercial HVAC and lighting distribution systems
Compatibility & Replacements
The S282-K6 is part of ABB’s S280 miniature circuit breaker family and offers compatibility with standard 35 mm DIN rail installations. Alternative specifications within the S280 series (such as S282-K10, S282-K16) support different amperage ratings. For UC-series (arc-extinguishing) variants, the S282UC-K6 provides enhanced arc suppression for DC applications. Always verify voltage ratings and trip curve compatibility with your control system before substitution.
