Residual current device RCD RX Legrand 402063 (AC, 40A, 4P, 30mA, 400V)

Description

LEGRAND 402063 – a residual current device designed to ensure electrical safety by detecting and automatically disconnecting the electrical circuit in case of a current leakage. This device, with a rated current of 40 A, effectively protects circuits where the current intensity does not exceed this limit and is suitable for use in low-voltage electrical networks. Its sensitivity of 30 mA ensures a quick response to even the slightest current leakages.

Specification

• Rated current: 40 A (ensures safe operation in circuits where current intensity does not exceed 40A)
• Number of poles: 4 (suitable for three-phase electrical systems)
• Rated voltage: 400 V
• Sensitivity: 30 mA (effectively detects even small current leakages)
• Type: AC (detects alternating current leakages)

Frequently asked questions (FAQ)

What is a residual current device used for?

A residual current device is designed to protect people from electric shock and reduce the risk of fire by detecting and automatically disconnecting the electrical circuit in case of a current leakage to earth.

What does 30 mA sensitivity mean?

30 mA sensitivity indicates the maximum current leakage limit, beyond which the device reacts and disconnects the power supply. This sensitivity is standard for personal protection in domestic and similar installations.

Can this device be used in a single-phase system?

Although this model is 4-pole, designed for three-phase systems, a 4-pole device can also be connected in a single-phase system, but it is important to ensure proper phase and neutral connection and conductivity.
