Diferencial Trifásico 63A/30mA | 4 Polos | Curva AC

The RV31 series residual current circuit breakers (RCCB) by Revalco are critical safety devices designed to provide superior protection against earth leakage currents and insulation faults in electrical installations. Available in Class AC and Class A, these units guarantee automatic circuit disconnection when the fault current exceeds the rated sensitivity, operating independently of the line voltage. They stand out for their robust design with fire-resistant plastic parts and an ergonomic arc-shaped handle that includes a central trip position; this feature allows for quick identification of a fault, as the handle cannot stay in that position through manual operation.

• Residual current circuit breakers for earth fault protection and isolation function.
• Available in Class AC and Class A models (special for pulsating DC currents).
• Configurations available in 2-pole (2P) and 4-pole (4P) versions.
• Rated currents ranging from 16A up to 100A.
• Available trip sensitivities: 10mA, 30mA, 100mA, 300mA, and 500mA.
• Contact position indicator window and transparent label holder.
• High short-circuit current resistance (Inc) of up to 10kA.
• Electromechanical operation independent of the power supply or line voltage.
• Protected connection terminals to prevent accidental contact.
• Mechanical and electrical endurance of 4000 operating cycles.
