5SM2626-2 SIEMENS

The 5SM2626-2 is a 2-pole residual current (RC) unit designed for use with 5SL4 miniature circuit breakers (MCBs). This RC unit provides enhanced protection against electrical hazards by detecting residual currents and quickly disconnecting the circuit. It is a type AC RC unit, meaning it is sensitive to alternating current faults. The rated current (In) of this unit is 63A, and it has a tripping current (IΔn) of 300mA, offering a balance between sensitivity and nuisance tripping prevention. The rated voltage (Un) is 230V AC, making it suitable for standard residential and commercial power systems. This selective RC unit ensures that only the faulty circuit is disconnected, minimizing disruption to other circuits. It enhances electrical safety by detecting earth leakage currents, preventing electric shocks and reducing the risk of fire. The 5SM2626-2 is easy to install and integrates seamlessly with compatible Siemens MCBs, providing a compact and reliable solution for residual current protection. Its robust design ensures long-term performance and compliance with relevant safety standards. This RC unit is an essential component for modern electrical installations, offering peace of mind and safeguarding against electrical faults.
