Product FAQs
10 answersWhat protection does the Schneider Electric M9R81463 offer?
It provides GFEP, or ground-fault equipment protection, with an electronic trip. Choose it for equipment ground-fault protection rather than personnel ground-fault protection.
How should I use the 63A current rating when selecting this breaker?
The 63A rating is the rated current, so use it when checking the current requirements of the circuit. Treat it separately from the ground-fault protection function, rather than as a ground-fault trip threshold.
How should I evaluate the 1.5kAIC interrupting rating?
At 240VAC, the 1.5kAIC interrupting rating sets the maximum available fault current the breaker can interrupt. Use that voltage-specific rating when checking the installation's fault-current requirements.
How do the four poles relate to a three-phase application?
This is a four-pole device rated for three-phase use. Account for all four poles in the circuit layout and wiring plan, rather than treating it as a three-pole device.
What mounting method should I plan for?
This breaker uses DIN rail mounting. Plan a rail-mounted installation rather than a bolt-on mounting arrangement.
What operating temperature range should I use for installation planning?
The operating temperature range is -25 to 60 °C. Choose an installation location where the temperature around the breaker remains within that range during operation.
How much space should I allow for the breaker body?
The body measures 3.2 in high, 2.8 in wide and 2.4 in deep. Use these dimensions to lay out the installation space, allowing additional room for conductor routing and terminal access.
How should I use the voltage ratings when selecting this breaker?
Match the application voltage and system configuration to the 480Y/277VAC or 415VAC rating. Evaluate the interrupting rating separately at the application voltage.
How should the terminal wire range guide conductor selection?
Use the 18 AWG to 2 AWG terminal wire range when planning conductor sizes. Coordinate conductor sizing with the circuit's ampacity requirements.
How should I use the 50/60Hz frequency rating during selection?
Match the circuit frequency to the 50/60Hz rating. Evaluate voltage and current ratings separately when selecting the breaker for an AC circuit.
