The Formula BLD Series Molded Case Circuit Breakers (MCCB) Frame Assembly forms the core protective structure for industrial circuit protection devices. Constructed from high-dielectric, glass-reinforced thermoplastic, this housing isolates high-current contacts, arc chutes, and trip units while providing an intuitive, color-coded front faceplate for clear contact position indication.

Key Features & Design Highlights

  • Color-Coded Status Indication: The central toggle opening features vivid Red (ON), Yellow (TRIPPED), and Green (OFF) visual status borders for immediate operational verification from the panel front.

  • Modular Internal Structural Channels: The rear housing frame integrates structural ribbing, guide slots, and isolation barriers designed to seat internal contact assemblies, arc quenching chambers, and terminal connectors securely.

  • Terminal Access & Mounting Holes: Pre-molded top and bottom terminal pass-through apertures enable simple busbar or cable lug connections alongside secure multi-point screw mounting.

  • High-Dielectric Polymer Construction: Formulated from flame-retardant, arc-resistant engineering resin designed to withstand high mechanical stress and thermal loads during short-circuit events.

  • Accessory Window: Features an integrated side recess for standard auxiliary contact, shunt trip, or undervoltage release accessory indicator plates.

Technical Specifications

  • Product Series: Formula BLD Series

  • Component Type: Molded Case Circuit Breaker (MCCB) Main Housing / Front Cover

  • Status Indicators: Red (ON) / Yellow (TRIP) / Green (OFF)

  • Color Scheme: Dark Slate Gray / Charcoal

  • Mounting Type: Panel / Sub-plate Mounting

  • Applications: Low-Voltage Power Distribution Boards, Motor Control Centers (MCC), Switchboards, and Commercial/Industrial Electrical Panels

Custom Formula BLD Series Molded Case Circuit Breaker Frame / Housing — Project Questions

Can Formula BLD Series Molded Case Circuit Breaker Frame / Housing be customized for my project?

Jingmu develops custom molds and molded components from customer drawings or samples. Share the part geometry, assembly requirements, material specification and expected production volume so our engineering team can review feasibility.

What information is needed to quote this component?

Send 2D drawings or 3D CAD files, the required material, key dimensions and tolerances, expected quantities and any electrical or environmental requirements. If drawings are unavailable, contact us to discuss a sample-based review.

How are material and manufacturing requirements confirmed?

The team reviews material selection, mold structure, assembly fit and inspection needs during the DFM stage. Final specifications, trial requirements and delivery timing are agreed for the individual project before production.

How We Work

Our 8-Step Process

From requirement review to final delivery, each stage is managed against the agreed technical and quality requirements.

01. Requirement Review

Review the application, customer drawings, 3D models, material requirements, tolerances and technical specifications. Confirm manufacturability through DFM analysis and agree on key quality requirements.
