Residual current circuit breaker P 312 2P C 32 A 30 mA type AC, DX3 series 411016

Protection and reliability in one device

The differential-overcurrent breaker P 312 2P C 32 A 30 mA AC from the DX³ series is a comprehensive solution ensuring safety for electrical installations and personnel. It combines the functions of a differential and overcurrent breaker, providing effective protection against the consequences of short circuits, overloads, and electric shocks. This is an ideal choice for both professional installers and end users seeking reliable protection.

Functionality and design

This two-pole breaker, with a width of 2 modules and designed for mounting on a TH35 rail, features a rated current of 32 A and a differential current of 30 mA. Its C characteristic ensures delayed tripping during brief overloads, which is particularly important when operating equipment with electric motors or other impulse loads. Equipped with a mechanical lock, it prevents accidental re-energization after shutdown due to a fault. The rated short-circuit breaking capacity is 6 kA, guaranteeing effective protection in the event of a short circuit in the installation.

Application and compatibility

The P 312 breakers from the DX³ series are compatible with the HX³ Optimal Power Distribution System up to 125 A, enabling wireless connection to the electrical installation. The possibility of adding additional DX³ series accessories—auxiliary contacts, under-voltage and over-voltage releases, or remote actuators—allows the device to be customized to meet the specific requirements of individual installations. The terminal acceptances support single-core conductors from 0.75 mm² to 16 mm² and multi-core conductors from 0.75 mm² to 10 mm², ensuring flexibility in connecting various cable types. The device has an IP20 protection rating, providing protection against finger contact and solid objects larger than 12.5 mm.
