Residual current circuit breaker P304 4P 80A 30mA TYPE AC DX3 411705

Residual Current Device (RCD) P304 DX³ is a key element ensuring safety in electrical installations. The device is designed to protect people and equipment from electric shock and the effects of short circuits and overloads. This model, with a rated current of 80A and a sensitivity of 30mA, is perfect for both home and commercial installations.

Functionality and Application

The AC type RCD reacts to leakage currents that can occur due to insulation failure or direct contact with live conductors. This minimizes the risk of electric shock. The four-pole design (4P) allows for the protection of the entire three-phase circuit with a neutral conductor. This is particularly important when powering devices with higher power or in places with an increased risk of failure.

DX³ series circuit breakers are characterized by high reliability and the ability to cooperate with the HX³ Energy Optimal Distribution system up to 125A, which enables wireless connection to the electrical installation. Additionally, compatibility with a wide range of auxiliary equipment (auxiliary contacts, release devices) allows you to adapt the functionality of the circuit breaker to the specific needs of the installation.

Technical Characteristics and Installation

The P304 DX³ circuit breaker has a number of features that affect its performance and durability:

• Short-circuit strength (Icw): 10 kA – ensures resistance to the effects of short circuits in the installation.
• Wire cross-section: Possibility of connecting stranded wires with a cross-section from 0.75 mm² to 35 mm² and solid wires from 0.75 mm² to 50 mm². This allows adaptation to different types of wires used in electrical installations.
• Rated voltage: 400 V – standard voltage in most electrical installations.
• Protection degree (IP): IP20 – provides protection against finger contact and solid objects larger than 12.5 mm.
• Width: 4 modules – compact dimensions make it easy to install in electrical switchboards.
• With lock: Yes - prevents accidental switching on of the circuit breaker after it has been switched off by the protection device.

Installation is done on a DIN rail, which is standard in most electrical switchboards. The built-in test button allows for regular checking of the correct operation of the residual current device, which is crucial for ensuring continuous safety of use.

Safety and Compliance with Standards

The P304 DX³ circuit breaker meets the requirements of EN 61008-1 standard, which guarantees its compliance with European safety standards. The rated impulse withstand voltage Uimp is 4 kV, which ensures resistance to overvoltages in the electrical network. The ambient temperature in operating conditions is in the range of -25°C to 60°C, which allows it to be used in various environmental conditions.
