Residual current circuit breaker P 312 2P B 10 A 30 mA type A 10 kA DX3 series 411286
The P 312 2P B 10 A 30 mA Type A 10 kA DX3 residual current circuit breaker is a reliable device that combines protection against electric shock with protection against the effects of short circuits and overloads. This solution is ideal for both professional installers and end users who value safety and convenience.
Protection and functionality in one device
This two-pole (2P) breaker with B characteristic ensures rapid response to short-circuit currents, safeguarding the electrical installation from damage. The rated current of 10 A makes it suitable for protecting circuits with medium load. Additionally, the residual current sensitivity of 30 mA guarantees high effectiveness of shock protection, minimizing the risk of injury. The short-circuit breaking capacity of 10 kA ensures effective intervention in case of severe disturbances.
Installation and compatibility
The P 312 DX3 breaker is designed for mounting on a TH35 rail, simplifying and accelerating installation. Its compact dimensions—4 module widths—allow efficient use of space in the distribution board. The device is compatible with the HX³ Optimal Power Distribution System up to 125 A, enabling wireless connection to the electrical installation. Compatibility with various auxiliary devices (auxiliary contacts, signaling contacts, trip units) enhances its functionality and adaptability to individual requirements.
Safety and testing
Equipped with a test button, the breaker allows regular verification of the residual current protection function—a simple procedure ensuring the protection remains fully operational. A lockout mechanism prevents accidental re-energizing after tripping. The IP20 protection rating ensures protection against finger contact and ingress of solid objects larger than 12.5 mm. The terminal accepts single-core conductors from 0.75 mm² to 16 mm² and multi-core conductors from 0.75 mm² to 10 mm², providing flexibility when connecting different cable types.
