Overview

The TE Connectivity Potter & Brumfield W58 Series thermal circuit breaker (SKU: 1-1393249-9) delivers precise overcurrent protection for industrial and commercial electrical systems. This single-pole, series-trip circuit breaker is rated for 5A current with a dual voltage capability of 250VAC and 50VDC, making it suitable for both AC and DC applications. The white housing provides high visibility and easy identification in control panels, enclosures, and distribution systems. Designed for reliability in demanding environments, the W58 series features a thermal trip mechanism that responds quickly to overcurrent conditions, preventing equipment damage and electrical hazards. Its compact 1-pole design ensures straightforward installation in tight spaces, while the series trip design guarantees consistent performance across repeated overload events. The breaker meets UNSPSC code 39121601 for general industrial circuit protection components. Common applications include machine control panels, power distribution units, industrial machinery, and commercial electrical systems where reliable circuit protection is critical. The 5A rating makes it ideal for protecting sensitive electronics, control circuits, and low-power industrial equipment. Compatible with standard electrical enclosures, the W58 series integrates seamlessly into existing systems without requiring special modifications.
