SIEMENS 5SV3346-3 RCCB Type F 63A 4-Pole 30mA 400V Short-Time Delayed

The SIEMENS 5SV3346-3 is a high-quality residual current circuit breaker (RCCB) from the Siemens Industrial Sector, designed for reliable protection against electric shock and fire hazards. This 4-pole Type F RCCB is short-time delayed, making it suitable for circuits with high inrush currents or where selective tripping is required. With a rated current of 63A and a rated residual current of 30mA, it provides robust protection for commercial and industrial applications.

Advantages

Type F RCCB ensures protection against pulsating DC and mixed frequencies up to 1 kHz, ideal for modern electronic loads. Short-time delayed characteristic prevents nuisance tripping from transient surges. Compact 4TE design saves space on DIN rail. High short-circuit withstand capacity of 10kA ensures safety under fault conditions.

Suitable for

• Industrial control panels
• Commercial building distribution boards
• Circuits with variable frequency drives, UPS systems, or LED lighting
• Applications requiring selective coordination with upstream devices
