ABB S202P-K6NA miniature circuit breaker, a 2-pole 6 A K curve thermal-magnetic MCB from the System pro M compact S200P range for control panels, auxiliary circuits and inductive loads.
The ABB S202P-K6NA is a compact and dependable 2-pole miniature circuit breaker from the ABB System pro M compact S200P range, designed to protect electrical circuits against overloads and short circuits. With a K curve tripping characteristic and 6 A rated current, it is well suited to circuits with higher inrush currents, including control transformers, motors, solenoids and inductive loads.
As part of ABB’s professional circuit protection range, the S202P-K6NA combines thermal-magnetic protection with current-limiting performance to help reduce fault energy during short-circuit conditions. Its compact DIN rail format supports fast installation in industrial control panels, distribution boards, machinery cabinets and OEM electrical assemblies.
With a 2-pole configuration, the S202P-K6NA provides simultaneous protection and isolation across two conductors. Its 6 A rating makes it suitable for auxiliary circuits, control wiring and equipment protection where reliable operation and reduced nuisance tripping are important.
Miniature circuit breakers such as the ABB S202P-K6NA automatically disconnect electrical circuits when overload or short-circuit faults occur. This helps protect wiring, connected devices and downstream equipment from damage caused by excessive current.
The K curve characteristic is designed for loads that can draw higher inrush current during start-up. This makes the S202P-K6NA a practical choice for control transformers, motor-related auxiliary circuits, solenoids and industrial automation systems where nuisance tripping must be reduced while maintaining dependable protection.
