Betagard Residual Current Circuit Breakers, Type A, applicable in networks with AC and DC – 5SV3346-6RC

Product Description

Betagard RCCB, Type A – 5SV3346-6RC

The Siemens 5SV3346-6RC is a Betagard Residual Current Circuit Breaker (RCCB) from the SENTRON 5SV3 series, designed to provide reliable protection against electric shock and fire hazards in low-voltage electrical distribution systems. It automatically disconnects the supply when dangerous earth leakage (residual) current is detected, ensuring high safety for both people and equipment.

This device is of Type A, meaning it can detect both sinusoidal AC and pulsating DC residual currents, making it suitable for modern electrical installations with electronic loads such as UPS systems, inverters, LED drivers, and switching power supplies.

The 5SV3346-6RC is typically a 63 A, 4-pole (3P+N) RCCB with 30 mA sensitivity, designed for personnel protection in three-phase systems. It features a compact DIN rail mounting design and is widely used in residential, commercial, and light industrial applications.
According to Siemens datasheet, it has a 10 kA short-circuit rating, 30 mA tripping sensitivity, and 4-module width design, ensuring compact and reliable installation in distribution boards.
