Legrand 421073 Mounting Plate for 4P Circuit Breakers with Residual Current Module

The Legrand 421073 mounting plate is a professional-grade accessory engineered specifically for the secure installation of 4-pole DPX³ 160 circuit breakers equipped with a residual current module. Designed for integration into electrical distribution boards, this plate ensures that heavy-duty circuit protection devices are mounted with precision and stability on TH35 DIN rails or compatible mounting plates. It serves as a critical interface component, facilitating the organized and safe arrangement of electrical infrastructure in demanding environments.

Advantages

This mounting plate offers exceptional structural integrity, ensuring that circuit breakers remain firmly in place even in environments subject to vibrations or mechanical stress. By providing a dedicated mounting surface, it simplifies the installation process and ensures perfect alignment of the protective equipment within the cabinet. 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.
