the Polycab (10K) 40 Ampere 300mA, 4-Pole (FP) Polycarbonate RCCB offers robust safety features, durable construction, and ease of installation, making it an indispensable component for ensuring electrical safety, Equipped with advanced technology, it rapidly detects abnormal currents and automatically disconnects the circuit to prevent accidents and damage, Its 300mA sensitivity ensures prompt detection and interruption of residual currents, significantly reducing the risk of electric shock and other hazards

• Rating: This RCCB has a current rating of 40 Amperes, indicating the maximum current it can handle safely. The rating should match the current requirements of the electrical circuit it is protecting.

• Sensitivity: The sensitivity of 300mA (milliamperes) indicates that this RCCB will trip when it detects a current imbalance of 300mA or more. RCCBs are critical for protecting against electrical shock and fires caused by ground faults or leakage currents. A 300mA sensitivity level is less sensitive compared to lower sensitivity options, and it provides protection against larger leakage currents.

• Poles: It is a 4-Pole (FP) RCCB, meaning it is a four-pole device. Four-pole RCCBs are used to protect all four conductors of a three-phase circuit, including the live, neutral, and two additional poles for other functions. They are commonly used in three-phase electrical systems.
