Product description

The Siemens 5SV3646-6 is a 4-pole residual current operated circuit breaker (RCCB) of Type A. It is rated for a current of 63A (In) and a residual current of 300mA (In), with a nominal voltage (Un AC) of 400V. This device provides essential protection against electric shock and fire hazards.

This RCCB is suitable for a variety of applications, including main power distribution in industrial facilities, commercial buildings, and power distribution boards where a higher current rating is required. Its Type A classification means it detects both sinusoidal AC residual currents and pulsating DC residual currents.

Stanlo Automation, a veteran-owned supplier of surplus industrial automation parts, carries the Siemens 5SV3646-6. We help businesses find the components they need to keep their systems running efficiently. Partner with Stanlo for reliable and cost-effective automation solutions.
