Product description

The Siemens 5SV3444-6 is a 4-pole, type A residual current operated circuit breaker (RCCB) with a higher sensitivity for fault current. It features a rated current of 40 A, a residual current sensitivity of 100 mA, and a rated operational voltage of 400 V AC. This higher mA rating is typically used for fire protection or for circuits where nuisance tripping is a concern with lower sensitivity breakers.

This RCCB is well-suited for industrial applications, machinery protection, or situations requiring a balance between fault detection and preventing unwanted interruptions. Its 100 mA sensitivity offers a different level of protection compared to standard 30 mA devices.

Stanlo Automation, a veteran-owned surplus distributor, offers the Siemens 5SV3444-6. We provide reliable and cost-effective solutions for industrial automation, ensuring you get quality parts for your operational needs.
