Siemens 5SV33464KK14 SENTRON 5SV3 interruttore differenziale tipo B+ 63A 4 poli 30mA

The Siemens 5SV33464KK14 is a high-quality Residual Current Circuit Breaker (RCCB) from the SENTRON 5SV3 series. Designed for reliable protection against electric shock and fire hazards, this device is ideal for use in residential, commercial, and industrial installations. With a rated current of 63A and a rated residual current of 30mA, it ensures safe operation in sensitive circuits. The Type B+ tripping characteristic provides enhanced protection for AC, pulsating DC, and smooth DC residual currents, making it suitable for modern electrical systems with electronic loads.

Advantages

This RCCB offers superior safety and reliability. Its Type B+ characteristic ensures comprehensive protection against all types of residual currents, including smooth DC, which is common in devices like inverters and variable frequency drives. The compact 4-module design saves space on DIN rail installations, while the high short-circuit withstand capacity of 10kA (with backup fuse) ensures robust performance. The device complies with international standards IEC 61008-1 and IEC 62423, guaranteeing quality and safety.

Suitable for

• Residential electrical panels
• Commercial building distribution boards
• Industrial control systems
• Circuits with electronic loads (e.g., UPS, drives, chargers)
• Applications requiring Type B+ residual current protection
