Frequently Asked Questions

What is the SIEMENS 5SJ4 miniature circuit breaker used for?

The SIEMENS 5SJ4 D-Curve miniature circuit breaker protects branch circuits in industrial control panels and equipment from overloads and short circuits. Its D-Curve trip characteristic handles high inrush loads like motors and transformers. Rated 8 A, 240V AC/60V DC, it is suitable for global installations requiring UL489 certification.

What are the specifications of the SIEMENS 5SJ41088HG40?

The SIEMENS 5SJ41088HG40 is a 1-pole D-Curve miniature circuit breaker rated 8 A. It has a max AIR rating of 14kA at 240V AC, AC voltage rating 240V AC, DC voltage rating 60V DC, and screw clamp terminals. It is part of the 5SJ4 series and mounts on a DIN rail.

Where to buy the SIEMENS 5SJ4 circuit breaker worldwide?

You can source the SIEMENS 5SJ4 series miniature circuit breaker from 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time on the 5SJ41088HG40 or other Siemens breakers.

How to select the right SIEMENS miniature circuit breaker for an application?

Select a Siemens MCB by matching voltage (AC/DC), current rating, and interrupting capacity to your circuit. For motor loads with high inrush, choose a D-Curve type like the 5SJ4 series. Ensure the terminal connection (e.g., screw clamp) fits your wiring. Always verify UL489 or IEC certification for your region.
