Schneider Electric 10A Miniature Breaker
This Schneider Electric M9F21110 is a single-pole miniature circuit breaker rated at 10 amps. It provides overcurrent protection for electrical circuits in residential and commercial installations. The unit is supplied new and was first listed by the manufacturer on 30 January 2020. It functions as a circuit breaker accessory within a distribution board.
Suits 10A single-pole protection needs
Installers fitting a 10 amp single-pole breaker for lighting or socket circuits will find this device matches the requirement. It is not suitable for circuits requiring a higher current rating, multi-pole configuration, or residual current protection. Buyers needing different amperage or pole counts must select an alternative model.
10 amp single-pole rating decides fit
The defining specification is the 10A, 1-pole rating marked on the M9F21110. This value must match the circuit design and the conductor size it protects. Verify the required amperage and pole count before purchase to ensure correct application.

Questions about this item
How is the 1 pole 10 A breaker mounted and what step is often missed?
Clip the unit onto a standard DIN rail until the latch clicks; the step often missed is verifying the latch is fully seated so the breaker cannot shift under vibration
What maintenance or replacement will the 10 A miniature circuit breaker need later?
No routine maintenance is required; replace the unit if it trips repeatedly without an overload or if the toggle mechanism feels loose
What limit appears first on the 10 A single pole breaker during sustained use?
The 10 A thermal trip curve is the first limit reached under continuous load, opening the circuit before the magnetic element operates
