Product description

The Siemens 5SL6416-7 is a 4-pole miniature circuit breaker designed for comprehensive protection of four-wire electrical circuits, including three-phase with a neutral. It offers a 6kA breaking capacity at 400V and a Type C tripping characteristic, rated for 16A, making it suitable for applications with moderate inrush currents.

This circuit breaker is widely used in industrial facilities, commercial buildings, and complex electrical installations where protection of all four conductors (three phases and neutral) is necessary. It is particularly useful for systems where unbalanced loads or neutral current protection is a concern.

Stanlo Automation, a veteran-owned surplus parts distributor, is pleased to offer the Siemens 5SL6416-7. We are committed to providing reliable and cost-effective industrial automation components, ensuring your critical systems remain operational with quality surplus parts.
