SIEMENS 5SV36468 interruptor diferencial, tipo A, 63 A, 300 mA, 4 polos, 400 V, selectivo

Selective RCCB with a rated residual operating current of 300 mA and 63 A rated current, designed for reliable protection in three-phase systems up to 400 V.

Overview

The SIEMENS 5SV36468 is a 4-pole (3P+N) residual current circuit breaker (RCCB) of Type A, suitable for detecting AC and pulsating DC residual currents. It is selective (time-delayed) to ensure coordination with downstream protective devices, making it ideal for fire protection and system availability in industrial and commercial installations.

What stands out

• Selective tripping behavior prevents unwanted shutdowns of healthy circuits.
• Type A detection covers AC and pulsating DC residual currents.
• Rated current of 63 A and residual operating current of 300 mA suit high-load circuits.
• Compact 4-module width (72 mm) saves space on DIN rail.
• Rated conditional short-circuit current of 10 kA ensures robustness.
