Product FAQs
7 answersWhat circuit ratings should I check before selecting the Schneider Electric M9R44225?
The Schneider Electric M9R44225 is rated 25A for a single-phase circuit, with two poles and a 50/60Hz frequency rating. Use these ratings when reviewing the circuit current, pole count and supply frequency.
What conductor sizes and terminal torque should I use?
The box-lug terminals accept conductors from 18 AWG through 2 AWG. Select the conductor size for the circuit requirements within that range, then tighten the terminals to 31.0 lb-in (3.5 N·m).
How should I plan mounting space for this device?
This device mounts on DIN rail. Its dimensions are 3.2 in high, 1.4 in wide and 2.4 in long; use these dimensions to plan rail space and enclosure clearance.
What temperature limits should I consider for the installation?
The operating temperature range is -25 to 60 °C, and the calibration temperature is 40°C. Check the expected temperature at the device location against the operating range, and use 40°C as the calibration reference.
How do the toggle and trip indicator help during operation?
The toggle provides manual operation, while the trip indicator helps you recognize a trip during troubleshooting. Investigate the cause of a trip before restoring power.
How should I interpret the 480Y/277VAC voltage rating?
The 480Y/277VAC rating applies to a wye system. Check both the circuit voltage and the supply configuration when selecting the device.
How do I use the 10kAIC interrupting rating when selecting this device?
The interrupting rating is 10kAIC at 240VAC. For a 240VAC application, verify that the available fault current at the installation point does not exceed this interrupting rating.
