Residual current protection 4-pole design (3P+N) Type A sensitivity (AC and pulsating DC) 30 mA earth leakage detection 25 A current rating Suitable for 400 V systems

Product description

The Siemens 5SV3342-6 is a 4-pole Residual Current Circuit Breaker (RCCB). It is designed to provide comprehensive protection against indirect contact and also offers protection against direct contact with hazardous parts. This Type A device detects sinusoidal AC and pulsating DC residual currents, with a 30 mA earth leakage sensitivity. It is rated for a nominal current (In) of 25 A and operates at a rated voltage (Un AC) of 400 V.

This 4-pole RCCB is commonly used in three-phase electrical systems for applications requiring residual current protection on all three phases and the neutral conductor. It is suitable for industrial machinery, large commercial installations, and systems with higher power demands.

Stanlo Automation, a veteran-owned distributor of surplus industrial automation parts, offers the Siemens 5SV3342-6. We provide reliable access to quality components, ensuring your industrial systems benefit from effective safety measures.
