Legrand 402025 2P 40A 30mA RCCB

Legrand 402025 2P 40A 30mA RCCB (Residual Current Circuit Breaker)

The Legrand 402025 2P 40A 30mA RCCB is a Residual Current Circuit Breaker designed to detect earth leakage currents and disconnect the circuit immediately when a leakage current exceeds 30mA. This provides effective protection against electric shocks and electrical hazards, ensuring user safety and system reliability.

Key Features

• Rated current 40A: Suitable for circuits with medium to high load requirements.

• 30mA residual current sensitivity: Provides enhanced protection for users by instantly disconnecting the power supply when the leakage current exceeds 30mA.

• 2-pole design (2P): Protects both phase and neutral conductors, ensuring comprehensive safety for single-phase systems.

• Fast leakage detection: Responds immediately to earth leakage faults, preventing electric shock and fire risks.

• Easy installation: DIN rail mounting allows quick setup and seamless integration into existing electrical panels.

• Compact and durable design: Fits standard distribution boards and is ideal for residential and light commercial installations.
