  • Product typeCircuit Breakers
  • 30 A rated current handles heavy loads
  • C-curve trip profile suits inductive motor starts
  • Two-pole design protects both live conductors
  • Schneider Electric build quality ensures reliable operation

Circuit Breaker 30A 2 Pole C Curve

Schneider Electric Miniature Circuit Breaker rated 30 Amps with a C Curve characteristic and two poles. It provides overcurrent protection for electrical circuits in residential or commercial installations. New condition unit supplied as a single protective device.

C Curve two-pole protection

The C Curve trip profile tolerates moderate inrush currents while still disconnecting sustained overloads and short circuits. Two-pole construction interrupts both live conductors simultaneously for single-phase supplies. No additional accessories or software are included with the breaker.

30 Amp rated current

The 30 Amp rating determines the maximum continuous current the breaker can carry without tripping. Circuits requiring a different ampere rating or a different trip curve will need an alternative device. First listed by the manufacturer in 2019.

Questions about this item

Will the 30 A C-curve breaker need periodic recalibration or internal part replacement?

No recalibration or user-replaceable parts are required; the sealed Schneider Electric unit is designed to operate for its service life without internal maintenance.

What is the first limit reached when the 30 A breaker carries continuous load?

The thermal element trips once current exceeds 30 A for a sustained period, protecting the circuit before conductor temperature becomes critical.

How much heat does the 2-pole breaker dissipate when running at full rating all day?

At 30 A the device generates modest warmth typical for a C-curve miniature breaker; no active cooling is needed in a standard enclosure.
