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

SQUARE D

SQUARE D 9080GCB20 2 A 250 V AC 1-pole DIN circuit breaker

SKU CH-F3YP-V2K1F

A 1-pole DIN-rail thermal-magnetic breaker rated 2 A at 250 V AC for copper wire 16–10 AWG

  • 2 A rating protects low-current circuits
  • 250 V AC maximum handles standard control voltage
  • DIN rail mount snaps onto standard track
  • 16–10 AWG copper range accepts common wire sizes
  • UL 1077 and CSA C22.2 No 235 listed for compliance

Thermal magnetic protection for DIN rails

The SQUARE D 9080GCB20 is a single-pole circuit protector rated at 2 A and 250 V AC. It mounts on standard DIN track and accepts copper conductors from 16 AWG to 10 AWG. This breaker suits control panels and machinery circuits requiring compact overcurrent protection. Builders needing higher current ratings or multi-pole configurations should select a different model.

Thermal magnetic operation with standard compliance

The device uses thermal magnetic tripping to interrupt fault currents while tolerating brief inrush. It meets DIN 57470, UL 1077 and CSA C 22.2 No 235 standards for supplementary protection. The black housing measures 3.11 in long, 3.15 in deep and .5 in wide for dense rail mounting. No auxiliary contacts or remote signalling features are included.

2 A rating defines the protection limit

The 2 ampere current rating is the single specification that determines whether this protector matches the load. It will trip on sustained overcurrent above this value, so the circuit design must stay within the limit. Verify the application current before purchase.

Questions about this item

How do I install the 9080GCB20 on a DIN rail and what step is often missed?

Clip the single-pole housing onto a standard DIN rail; the step often missed is tightening the terminal screws to the 10 AWG maximum wire size after seating the breaker.

What maintenance or replacement will the 9080GCB20 need over time?

The thermal-magnetic mechanism is not serviceable; replace the breaker if it trips repeatedly at 2 A or shows discoloration on the black housing.

What limit appears first when the 9080GCB20 runs continuously at full load?

The 2 A thermal trip curve activates before the 250 V AC magnetic threshold, so sustained currents above 2 A will open the circuit first.
