Siemens aardlekautomaat 4P C16 6KA 5SU1346-7FP16 Type-A 30mA 4TE RCBO

The Siemens 5SU1346-7FP16 is a high-quality Residual Current Circuit Breaker with Overcurrent Protection (RCBO) designed for reliable protection in electrical installations. This 4-pole device combines overcurrent and residual current protection in a single unit, saving space and simplifying wiring. With a rated current of 16 A and a C tripping characteristic, it is ideal for protecting circuits with moderate inrush currents, such as lighting and general power outlets. The Type A residual current sensitivity (30 mA) ensures protection against sinusoidal AC residual currents and pulsating DC residual currents, making it suitable for modern electronic loads.

Advantages

Combined overcurrent and residual current protection in one compact device reduces installation time and panel space. The 4-pole design allows for three-phase applications, and the 6 kA short-circuit breaking capacity ensures robust fault handling. The DIN rail mounting and 4 module units (4 TE) make it easy to install in standard distribution boards.

Suitable for

• Three-phase circuits requiring both overcurrent and residual current protection
• Commercial and industrial electrical panels
• Protection of circuits with electronic equipment (Type A sensitivity)
• Lighting, socket outlets, and small motor circuits
