Mounting Plate / Chassis Component – Electrical Equipment Manufacturing

Q: What is the primary function of a mounting plate in a power line filter panel?

To provide secure mechanical mounting for filter components while ensuring proper electrical grounding and EMI/RFI containment through conductive enclosure design.

Q: How do you ensure proper grounding with these chassis?

Through dedicated grounding studs with star washers that penetrate surface coatings, maintaining <0.1Ω resistance to panel ground as per IEC 61439 requirements.

Component Specifications

Definition

A rigid metallic chassis or mounting plate designed to securely house and support power line filter components (such as capacitors, inductors, and chokes) within an electrical panel. It provides structural integrity, proper component alignment, electrical grounding, and thermal management while isolating electromagnetic interference from sensitive equipment.

Working Principle

Provides mechanical support and electrical grounding for filter components. The chassis acts as a Faraday cage to contain electromagnetic interference (EMI) and radio frequency interference (RFI), while the mounting plate ensures precise component positioning for optimal electrical performance and heat dissipation.

Materials

Cold-rolled steel (CRS) with zinc plating (5-8μm) or aluminum alloy (6061-T6) with anodized coating (15-25μm). Thickness: 1.5-3.0mm. Surface resistivity: <0.1Ω/sq for grounding.

Technical Parameters

Dimensions Standard panel sizes: 19" rack (482.6mm width) or custom
Mounting Holes M4 or M5 threaded inserts, 10-12mm spacing
Surface Finish RAL 9005 (black) powder coating, 60-80μm
Weight Capacity 5-15kg distributed load
Grounding Points Minimum 2× M6 studs with star washers
Flatness Tolerance ≤0.5mm/m²

Standards

ISO 12944-5, DIN 43694, IEC 61439-1
