ABB S282K1A - 1A, 480VAC, 2-Pole, Circuit Breaker

Meet the ABB S282K1A, a purpose-built 2-pole circuit breaker engineered for dependable overcurrent protection in demanding electrical environments. With a precise 1A current rating and a high 480VAC voltage allowance, this device safeguards critical circuits in panelboards, switchboards, and control panels where reliability matters most.

• Current rating: 1A
• Voltage rating: 480VAC
• Poles: 2-Pole
• Type: Circuit Breaker
• Applications: Industrial, commercial, and OEM panel installations requiring robust, coordinated protection

The two-pole design ensures both conductors trip together, delivering safer shutdowns and cleaner coordination for circuits feeding motors, relays, and control devices. This makes the S282K1A an ideal choice for motor control centers, machine panels, and automation enclosures where compact size and reliable fail-safe performance are essential.

Why this ABB breaker stands out

Backed by ABB’s engineering lineage and global support, the S282K1A delivers consistent performance in real-world installations. The 2-pole configuration simplifies wiring, improves short-circuit handling in distribution panels, and provides clear, immediate protection for low-current control circuits and instrumentation lines—without compromising space in tightly packed control rooms.

Use cases and ideal audiences

• Industrial automation panels that house sensors, actuators, and logic controllers requiring tight overcurrent protection
• Panelboards and switchboards in manufacturing environments where dependable, coordinated tripping is critical
• OEM equipment enclosures needing a compact, reliable 2-pole breaker to protect delicate control circuits

Practical tips for installation and operation

Confirm that your system voltage aligns with the 480VAC rating and that the protected load current does not exceed 1A. Plan for simultaneous trip behavior by wiring your circuit to both poles. When integrating into new or existing panels, ensure the breaker fits the enclosure’s specifications and that it complements the panel’s protection strategy for motor control or automation circuits.
