2-pole configuration C-curve characteristic 10kA interrupting rating High 25A current capacity Durable Siemens construction

The Siemens 5SL4225-7 is a 2-pole miniature circuit breaker providing robust overcurrent and short-circuit protection. It features a C-curve tripping characteristic, making it suitable for circuits with moderate inrush currents, and is rated for 400V with a 10kA breaking capacity. This model is rated at 25 Amperes.

This circuit breaker is designed for applications requiring higher current capacity while maintaining C-curve performance. It is commonly used in industrial distribution panels, commercial building main feeders, and for protecting circuits powering larger machinery or equipment with moderate starting surges.

Stanlo Automation, a veteran-owned surplus distributor, offers the Siemens 5SL4225-7. We are committed to providing essential automation and electrical parts that ensure system reliability and operational efficiency, offering competitive pricing and quick access to vital components.
