Schneider Electric M9F11110 Miniature Circuit Breaker

Product Description

The SCHNEIDER ELECTRIC M9F11110 is a 1-pole miniature circuit breaker rated at 10 amps and 240/415 volts AC. It uses a thermal-magnetic trip mechanism to provide both overload and short-circuit protection in a single compact device. With a breaking capacity of 10 kA at 240 VAC, it is suited for branch-circuit protection in residential, commercial, and light industrial electrical panels. The unit mounts on standard DIN rail and accepts wire sizes from 14 to 4 AWG through box lug terminals. Electricians and electrical contractors install this breaker as part of distribution board assemblies and sub-panel wiring projects.

The M9F11110 is designed for use in DIN rail panelboards and distribution enclosures where compact single-pole overcurrent protection is required. It is appropriate for 240 VAC single-phase branch circuits and 415 VAC three-phase systems where individual phase protection is needed. Its 18mm wide profile allows multiple breakers to be installed in tight panel layouts without sacrificing breaking capacity or reliability.

Key Features

• Thermal-magnetic trip mechanism provides overload and short-circuit protection
• 10 kA breaking capacity at 240 VAC for robust fault interruption
• Rated 10 amps at 240/415 VAC for broad voltage compatibility
• DIN rail mounting for fast, tool-assisted installation in standard enclosures
• Box lug terminals accept 14 to 4 AWG wire
• Automatic reset actuator type for straightforward recovery after a trip event

Compatibility

Designed as an OEM-style replacement or new-installation miniature circuit breaker for standard DIN rail panelboards and distribution enclosures requiring 1-pole, 10-amp, 240/415 VAC overcurrent protection.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize and lock out the panel before mounting or wiring the breaker. Secure the breaker firmly onto the DIN rail before making terminal connections, and verify that conductor size falls within the 14 to 4 AWG range supported by the box lug terminals. Do not exceed the rated ampacity or voltage of the breaker.
