Siemens 5SV16166KK16 RCBO, 1P+N, 16 A, 30 mA, typ A, charakteristika C, 6 kA

Residual current operated circuit-breaker with integral overcurrent protection (RCBO) in 1P+N configuration, rated 16 A with a 30 mA residual current sensitivity and C tripping characteristic. Combines fault current and overcurrent protection in a single 2-module-wide DIN rail device.

Overview

The Siemens 5SV16166KK16 is a combined residual current operated circuit-breaker with overcurrent protection (RCBO). It protects against both residual currents (earth faults) and overcurrents (overload and short-circuit) in a single device. The unit is designed for DIN rail mounting and occupies a width of 2 TE (36 mm). It has a rated current of 16 A, a rated residual current of 30 mA, and a tripping characteristic of type C. The residual current type is A, which detects alternating and pulsating direct residual currents. The rated switching capacity is 6 kA, and the rated voltage is 230 V AC at 50 Hz.

What stands out

• Combined protection: RCBO function in one compact unit
• 1P+N design with 2 TE width for efficient use of distribution board space
• Type A residual current detection for AC and pulsating DC fault currents
• C tripping characteristic for circuits with moderate inrush currents
• 6 kA switching capacity for reliable short-circuit interruption
• DIN rail mounting for standard installation
