Black DIN-rail circuit breaker, single pole, 0.5 in wide

SQUARE D

SQUARE D 9080GCB100 10 A 250 V AC DIN circuit breaker

SKU CH-S640-XQ5D8

DIN-rail thermal-magnetic circuit breaker rated 10 A at 250 V AC with CSA C22.2 No 235 and UL 1077 approvals

  • 10 A thermal-magnetic protection for reliable circuit safety
  • 250 V AC rating handles standard industrial control voltages
  • DIN-rail mount installs quickly in standard enclosures
  • CSA C22.2 No 235 and UL 1077 certified for code compliance
  • Compact 0.5 in width fits dense panel layouts

Single-pole DIN circuit protector

The Square D 9080GCB100 is a thermal-magnetic circuit protector rated at 10 amperes and 250 volts AC. It mounts on standard DIN track and occupies a single tier with one pole. The black housing measures 3.11 inches long, 0.5 inches wide and 3.15 inches deep.

Panels needing one-pole 10 A protection

This device suits control panels and equipment circuits that require a single-pole 10 A breaker with DIN mounting. It accepts copper conductors from 16 AWG to 10 AWG. Installations that need multi-pole protection, higher current ratings or a different mounting style should select another product.

10 A 250 V AC rating

The decisive specification is the 10 A at 250 V AC thermal-magnetic rating combined with the single-pole DIN configuration. The unit is listed to CSA C22.2 No 235 and UL 1077, and accepts 16 to 10 AWG copper wire. Verify that the application requires exactly this current, voltage and pole count before ordering.

Questions about this item

How do I install the 9080GCB100 on a DIN rail and which step is commonly missed?

Clip the 0.5 in wide housing onto a standard DIN rail, then tighten the NEMA terminal screws for 16–10 AWG copper wire; the step often missed is confirming the rail is grounded before energising the 10 A 250 V AC circuit.

What maintenance or replacement will the 9080GCB100 need over time?

The thermal-magnetic mechanism is sealed; no user-serviceable parts exist. Plan to replace the entire unit if it trips repeatedly at 10 A or shows discolouration on the black housing after a fault.

What limit appears first when the 9080GCB100 runs continuously at full load?

Sustained 10 A current heats the 3.15 in deep body until the thermal element trips — that thermal limit activates before the magnetic instantaneous trip under prolonged overload.
