SIEMENS 5SJ41106HG40 10A 1 Pole Circuit Breaker

SKU CH-5TWA-VDAJF

A 10 A single-pole miniature circuit breaker with B-curve thermal-magnetic trip, 14 kA interrupting rating at 240 V AC, and DIN-rail screw-clamp terminals for branch-circuit protection

  • 10 A thermal magnetic trip protects branch circuits
  • 14 kA interrupting rating at 240 V AC handles high fault currents
  • DIN rail mounting fits standard industrial enclosures
  • Screw clamp terminals accept 14 to 4 AWG conductors
  • UL 489 listed for branch circuit protection

IEC 10 A Miniature Breaker

This Siemens 5SJ4 series miniature circuit breaker provides 10 A branch-circuit protection on a single pole. It carries a B-curve thermal-magnetic trip and is rated for 240 V AC and 60 V DC with a 14 kA interrupting capacity at 240 V AC. The device mounts on standard DIN rail and accepts screw-clamp terminals from 14 AWG up to 4 AWG.

Installers needing single-pole AC

Electricians and panel builders who require a compact, DIN-rail device for 10 A lighting, receptacle or control circuits will find the ratings match common industrial and commercial specs. Projects that demand multi-pole switching, higher current ratings or a different trip curve should select an alternative model.

Screw-clamp terminals simplify wiring

The screw-clamp connection accommodates a wide conductor range from 14 AWG to 4 AWG, reducing the need for special lugs or ferrules. Reverse-feed capability adds flexibility when the breaker is fed from either end. No additional accessories or software are included in the package.

Questions about this item

What mounting rail does the 5SJ41106HG40 need?

It mounts on a DIN rail as indicated by the DIN Rail mounting style in the specifications.

Can the 10 A breaker share a DIN rail with older 63 A frame devices?

Yes, the frame size is listed as 63A/5SJ4 so it fits the same rail system as other 63 A frame breakers.

How do I verify the 5SJ41106HG40 is working after wiring?

Apply load up to 10 A and confirm the thermal magnetic trip does not operate; a sustained overload above 10 A should cause the breaker to open the circuit.
