The robust construction supports the weight and operational requirements of DPX³ series breakers, contributing to the overall longevity and reliability of the electrical distribution system.
Suitable for
Industrial electrical distribution panels
Commercial building power management systems
Installation of 4P DPX³ 160 circuit breakers with earth leakage modules
Upgrading or maintaining existing electrical switchgear
When it may not be suitable
This mounting plate is specifically engineered for the DPX³ 160 4P series and may not be compatible with other circuit breaker models or different frame sizes. It is not intended for use in environments where the mounting surface does not meet the specified rail or plate requirements.
Key specifications
Compatibility: DPX³ 160 4P circuit breakers with residual current module
Width: 100 mm
Depth: 200 mm
Height: 25 mm
Mounting compatibility: TH35 DIN rail, aluminium rail, or specific mounting plates
How to use
To install the mounting plate, first ensure that the power supply to the distribution board is disconnected. Align the plate with the designated TH35 DIN rail or the compatible mounting plate (Cat.Nos 0 206 11/61). Secure the plate firmly using the appropriate fasteners. Once the plate is fixed, position the 4P DPX³ circuit breaker with the residual current module onto the plate, ensuring it clicks or bolts into the designated slots. Verify that the device is level and securely attached before reconnecting the electrical supply.
What to consider before purchase
Verify the exact model of your circuit breaker to ensure it is a DPX³ 160 4P version.
Check the available space in your distribution board to accommodate the 100mm x 200mm dimensions.
Confirm that your existing rail or plate system is compatible with the mounting requirements.
Usage recommendations
Always adhere to local electrical safety regulations and manufacturer guidelines when installing circuit protection equipment. Ensure that all connections are tightened to the specified torque settings to prevent overheating or loose contacts.
