Residual current device P 302 2P 16 A 10 mA type AC, TX3 series 411502

Protection and Safety of Electrical Installations

The residual current device P 302 2P 16 A 10 mA type AC from the TX³ series provides reliable protection for electrical installations and personnel against electric shock. The device effectively detects leakage currents, minimizing the risk of hazards caused by insulation damage or direct contact with live conductors. It is a critical component ensuring safety in every electrical circuit.

Functionality and Application

Designed for DIN-rail mounting, this device is suitable for circuits with a voltage of 230 V and a rated current of 16 A. Its sensitivity to a differential current of 10 mA (type AC) makes it ideal for protecting people from the effects of electric shock. The two-pole (2P) construction allows disconnection of both phase and neutral conductors, ensuring complete protection. Additionally, the device features a mechanical lock that prevents accidental re-energizing after tripping.

Construction and Key Features

The TX³ series is distinguished by high manufacturing quality and durability. The P 302 device has an IP20 protection rating, providing protection against finger contact and ingress of solid objects larger than 12.5 mm. A short-circuit capacity of 10 kA ensures proper operation even during fault conditions in the installation. Its compact dimensions — 2 modules (35.6 mm) wide — facilitate installation in space-constrained distribution boards. The terminal accepts single-core conductors up to 50 mm² and multi-core conductors up to 35 mm², ensuring compatibility with various cable types used in electrical installations. Furthermore, the ability to integrate with auxiliary devices (auxiliary contacts, trip units) expands the device’s functionality and allows customization to meet specific installation requirements. The rated impulse voltage withstand (Uimp) is 4 kV, providing additional operational safety.
