Frequently Asked Questions

What is the SIEMENS 5SJ41058HG42 miniature circuit breaker used for?

The SIEMENS 5SJ41058HG42 is a D-Curve, 1-pole UL489 miniature circuit breaker rated at 0.5 A. It protects branch circuits in industrial control panels, HVAC equipment, and lighting systems against overloads and short circuits, handling both 277V AC and 60V DC applications.

What are the specifications of the SIEMENS 5SJ41058HG42?

This SIEMENS IEC miniature circuit breaker (MPN 5SJ41058HG42) is rated 0.5 A, 277V AC / 60V DC, with a maximum AIR of 10kA at 277V AC. It features a D-Curve trip characteristic, 1-pole design, screw-clamp terminals, and UL489 listing for DIN-rail mounting.

Where to buy the SIEMENS 5SJ41058HG42 worldwide?

3G Electric supplies the SIEMENS 5SJ41058HG42 miniature circuit breaker to customers worldwide. As a global industrial sourcing partner, we handle full logistics, customs clearance, and delivery to your site. Contact us for pricing and lead time on this UL489-listed 0.5 A, 277V AC / 60V DC unit.

How to select the right SIEMENS miniature circuit breaker for a 60V DC application?

For a 60V DC circuit, choose a breaker with a DC voltage rating at or above your system voltage, like the SIEMENS 5SJ41058HG42 rated 60V DC. Verify the current rating (0.5 A here) matches your load, and confirm the D-Curve trip characteristic suits motor or transformer inrush currents.
