Why Choose the ABB S302P-K2 Miniature Circuit Breaker?
The ABB S302P-K2 (SKU: 2CDS382001R0277) is a high-performance 2-pole miniature circuit breaker (MCB) designed to protect industrial electrical installations against overloads and short circuits. Part of the ABB System pro M Compact S300P series, it combines a compact modular design with a high fault-interruption capability for demanding control and distribution applications.
The S302P-K2 uses thermal overload protection together with rapid electromagnetic short-circuit tripping. This helps protect cables, motors, transformers, contactors and connected equipment while reducing the risk of damage and unplanned downtime. Its standard DIN rail format supports straightforward integration into control panels, distribution boards and industrial switchgear.
With a 2 A rated current, K tripping characteristic, 2-pole configuration and a 25 kA breaking capacity, the S302P-K2 is particularly suitable for inductive loads that can generate elevated starting currents during normal operation.

Dependable Protection for Inductive Loads
Miniature circuit breakers disconnect a circuit automatically when excessive current is detected. The thermal element responds to prolonged overloads, while the electromagnetic mechanism provides rapid interruption during short-circuit conditions. Together, these functions help protect conductors and connected equipment from overheating and severe fault currents.
A K curve circuit breaker is designed to accommodate the temporary inrush currents associated with inductive equipment. This makes the ABB S302P-K2 a practical choice for low-current motor circuits, transformers, solenoids, contactors and industrial control equipment that could cause unwanted operation of a more sensitive breaker.
Typical Applications
- Industrial control panels.
- Low-current motor circuits.
- Transformer protection.
- Contactors and solenoid-operated equipment.
- Machine building and OEM systems.
- Automation and process-control installations.
