SIEMENS 5SJ41138HG42 Miniature Circuit Breaker 13A 1 Pole D Curve 277V AC 60V DC 10kA DIN Rail

SKU CH-V4PH-1E4RE

A 13 A single-pole D-curve breaker rated 277 V AC and 60 V DC with 10 kA interrupting capacity, DIN-rail mountable for industrial circuits

  • 13 A single-pole protection with D-curve trip for high inrush loads
  • 10 kA interrupting capacity at 277 V AC for reliable fault clearance
  • 60 V DC rating extends use to low-voltage control circuits
  • DIN-rail mount with screw-clamp terminals accepts 14 to 4 AWG wire
  • Compact 4.76 × 0.71 × 2.75 in frame fits dense panel layouts

IEC Miniature Circuit Breaker

The SIEMENS 5SJ41138HG42 is a 13A single-pole IEC miniature circuit breaker designed for industrial circuit protection. It uses a D-curve thermal magnetic trip mechanism suited to loads with high inrush currents such as motors or transformers. The breaker is rated for 277V AC and 60V DC with a maximum interrupting rating of 10kA at 277V AC. It mounts on standard DIN rail for panel installation.

DIN Rail Mounting and Screw Clamp Terminals

The unit measures 4.76 in long, 0.71 in wide and 2.75 in deep, fitting a 63A frame size within the 5SJ4 series. A toggle actuator provides manual on and off control with clear trip indication. Screw clamp terminals accept conductors from 14 AWG up to 4 AWG, securing solid or stranded wire without specialised tooling. The compact single-pole width allows dense row mounting in distribution boards.

UL 489 Compliance and Application Limits

This breaker meets UL 489 requirements for branch circuit protection in industrial control panels. The D-curve characteristic requires higher instantaneous current to trip, so it is not suited for circuits needing fast short-circuit response on sensitive electronic loads. The 10kA interrupting capacity at 277V AC defines the maximum prospective fault current the device can safely clear. DC circuits are limited to 60V.
