Residual current device P 302 2P 40 A 30 mA type F (HPI) DX3 series 411591

Protection and Safety of Electrical Installations

The residual current device (RCD) P 302 2P 40A 30mA Type F (HPI) from the DX³ series is a critical component ensuring protection of people and equipment in electrical installations. Its purpose is to rapidly detect leakage currents and disconnect power in the event of a fault, minimizing the risk of electric shock and preventing fires caused by short circuits. This two-pole RCD, rated at 40A and with a sensitivity of 30mA, performs excellently in both residential and commercial installations.

Design and Application

The DX³ series RCD features a compact design—occupying only 2 modules on a DIN rail. Installation is simple and intuitive, with connections made via screws, ensuring secure and durable connections for single-core conductors from 0.75 mm² to 50 mm², or multi-core conductors from 0.75 mm² to 35 mm². The HPI (High Performance Immunity) type distinguishes this device with enhanced immunity to electrical disturbances, which is especially important in industrial environments or areas exposed to pulsating DC currents. This feature reduces the risk of unwanted tripping, ensuring uninterrupted power supply.

Advantages and Benefits

• High reliability: Compliance with EN 61008-1 standard guarantees high quality and safe operation.
• Protection against electric shock: 30 mA sensitivity ensures effective protection of persons from accidental contact with current.
• Immunity to interference: HPI type minimizes false tripping caused by network disturbances.
• Easy installation: Compact dimensions and screw terminals simplify installation and maintenance.
• Versatile application: Suitable for protecting circuits of various purposes—lighting, sockets, electrical appliances.
• Integrated test button: Enables regular verification of device functionality.
• Lockout feature: Provides additional safety during maintenance or repair work.
• Short-circuit withstand capacity: Withstands short-circuit currents up to 10 kA, protecting the installation from damage.
• Wide operating temperature range: Reliable operation from -25°C to +60°C ensures performance under diverse environmental conditions.

Additionally, P 300 series DX³ RCDs are compatible with the HX³ Optimal Energy Distribution System, enabling wireless integration into electrical installations, and work with a broad range of auxiliary accessories—such as auxiliary contacts, signaling devices, or undervoltage trip units—allowing customization of protection to meet individual user requirements.
