Residual current device PR 302 2P 63 A 30 mA type AC, DX3 series 410402

Safety and Protection in Your Electrical Installation

The residual current device (RCD) PR 302 is a critical component ensuring protection of people and equipment in electrical installations. This device, rated at 63 A, effectively detects leakage currents, minimizing the risk of electric shock and equipment damage. It is an AC-type RCD, meaning it provides protection against earth faults caused by both alternating and direct currents.

Design and Application

The two-pole PR 302 block is designed for installation in electrical distribution boards. Its compact dimensions and IP20 protection rating allow installation in various environmental conditions. It is intended for use in networks with voltage ranging from 170–253 V and frequency of 50 Hz. The mechanical lock prevents accidental adjustment or deactivation of the device, enhancing operational safety.

Key Features and Benefits

• Fast Response: 30 mA sensitivity ensures rapid detection of leakage currents, which is especially critical in residential and public areas.
• Versatility: Compatible with single-core conductors of 1.5–35 mm² and multi-core conductors of 1.5–25 mm², facilitating integration with diverse installation types.
• Durability: Rated impulse voltage withstand (Uimp) of up to 4 kV ensures resilience against voltage surges and electrical disturbances.
• Wide Temperature Range: Operates reliably in temperatures from -25°C to 70°C, making the PR 302 suitable for demanding environmental conditions.
• Safety: Integrated lock prevents accidental deactivation or setting changes, increasing overall installation safety.
• Overload Protection: Protects the circuit against overload and short-circuit — as is standard for devices in this class.
• Reliability: Pollution degree 2 ensures stable operation even in environments with elevated contamination levels.

This residual current device is a reliable solution for anyone prioritizing the safety of their electrical installation and the comfort of using electrical equipment. Its robust construction and high sensitivity provide effective protection against electric shock and equipment damage.
