Residual current circuit breaker P 312 2P C 25 A 30 mA type AC 10KA DX3 series 410981

Protection and safety in one device

Residual Current Circuit Breaker (RCCB) P 312 2P C 25 A 30 mA type AC 10kA from the DX3 series is a reliable solution providing comprehensive protection for electrical installations. It combines the functions of an overcurrent circuit breaker and a residual current device, protecting against the effects of overloads, short circuits and electric shock. This is an ideal solution for both professional installers and end-users looking for safety and comfort.

Functionality and application

This two-pole (2P) circuit breaker with a rated current of 25A and characteristic C is perfect for circuits with moderate loads, where devices with motors or other elements generating surge currents are present. Characteristic C allows it to react more slowly to short current spikes, so it tolerates starting devices with a motor well. The rated residual current of 30 mA provides effective protection against electric shock. The circuit breaker is designed to operate in AC networks with a voltage of 230V and a frequency of 50Hz.

Comfort of installation and diagnostics

The P 312 DX3 circuit breaker is characterized by a compact design – it takes up only 2 modules in width, which allows for optimal use of space in the switchgear cabinet. It also has a test button, allowing for regular checking of its correct operation. Flush mounting further improves the aesthetics of the installation. With a lock preventing accidental switching on after tripping of the protection. At the same time, the disconnectable N pole increases safety of use.

• Rated short-circuit breaking capacity at 10kA guarantees reliable operation even in the event of serious disturbances in the network.
• Wide range of wire cross-sections – from 0.75 to 16 mm² for solid wires and from 0.75 to 10 mm² for stranded wires – facilitates connection to various types of installations.
• Protection class IP20 provides protection against finger contact and against the ingress of solid objects larger than 12.5 mm, which increases safety of use.
• Compliance with IEC/EN 61009-1 standards confirms the high level of safety and reliability of the device, giving certainty of correct operation.
• The device cooperates with all auxiliary equipment (auxiliary and signaling contacts, undervoltage and overvoltage releases, remote drives and others), which provides great flexibility in configuring the protection system.
