Residual current device (RCD) RX3 2P 230V 25A 30mA TYPE A 402036

Modern electric shock protection for electrical installations

The RX3 type A residual current device is an advanced protective device that provides comprehensive protection against electric shock and the effects of current leakage.

Operating parameters and technical characteristics

The device operates at a rated voltage of 230V AC and a rated current of 25A, providing a sensitivity of 30mA for differential current. The short-circuit strength is 10 kA, and the impulse withstand voltage is 4 kV. The two-pole design occupies only 2 modules on a standard DIN rail (35.6mm width).

Operating temperature ranges from -25°C to +60°C with an IP20 protection rating. The cross-sections of the connected wires range from 0.75-50 mm² for single-core wires and 0.75-35 mm² for multi-core wires.

Construction and mounting compatibility

The housing is made of halogen-free materials in grey (RAL 7035). Mounting is performed on a standard DIN rail using quick connectors, and power supply is possible from both the top and the bottom.

The installation depth is 44 mm, and the total device depth is 77.8 mm. Mechanical resistance is class IK04.

Normative compliance and operating conditions

The residual current device complies with the requirements of the IEC 61008-1 standard. The environmental pollution degree is 2, allowing operation in normal industrial conditions. The operating frequency is the standard 50 Hz.

The device does not have selectivity or short-circuit release functions, which simplifies its operation and ensures an immediate response to dangerous current leakage.

The storage temperature range is from -40°C to +70°C, and the rated insulation voltage is 250V.
