  • Accepts 16–10 AWG copper conductors for secure wiring
  • Certified to CSA C22.2 No. 235 and UL 1077 standards

SQUARE D 9080GCB150 15 A DIN circuit breaker

The SQUARE D 9080GCB150 is a single-pole thermal-magnetic circuit protector rated for 15 A at 250 V AC. It mounts on a standard DIN rail and uses NEMA-style terminal blocks that accept copper conductors from 16 AWG to 10 AWG. The black housing measures 3.11 in long, 0.5 in wide and 3.15 in deep. It carries CSA C22.2 No 235, UL 1077 and DIN 57470 approvals.

Installation and common issues

Snap the breaker onto a 35 mm DIN rail and tighten the terminal screws to the torque printed on the label. Use only solid or stranded copper wire within the 16–10 AWG range; aluminium conductors are not supported. A frequent mistake is leaving a loose screw, which creates a hot spot and nuisance tripping. Verify that the rail is grounded and that the upstream over-current device coordinates with the 15 A rating.

What to check before ordering

Confirm that your control panel uses a 35 mm DIN rail and that the available width can accommodate the 0.5 in module. Ensure the system voltage does not exceed 250 V AC and that the load current stays at or below 15 A. Check that the wire you plan to use is copper and falls between 16 AWG and 10 AWG. This breaker is not suitable for DC circuits, higher voltages or multi-pole applications.

Questions about this item

How can I confirm the 15 A 250 V AC breaker is working after DIN-rail installation?

Switch the breaker on, apply a known load up to 15 A, and verify the circuit carries current without nuisance tripping; the thermal-magnetic mechanism will trip only on genuine overcurrent or short-circuit conditions.

What comes with the 9080GCB150 and what must I source separately?

The package includes the single-pole DIN-mount breaker with NEMA terminal blocks ready for 16 AWG to 10 AWG copper wire; you must supply the DIN rail, appropriate gauge copper conductors, and any upstream disconnect or enclosure.

Which version of the 9080GCB150 should I choose for a 15 A 250 V AC control circuit?

The listed model is a single-pole, one-tier thermal-magnetic protector rated 15 A at 250 V AC with CSA C22.2 No. 235 and UL 1077 compliance; select this version when those exact ratings match your control-circuit requirements.
