TSM Iron Base Distribution Box

Enhance safety and aesthetics in your electrical installations with the CDADA TSM Iron Base Distribution Box a premium modular enclosure solution from Shanghai DADA Electric CO., LTD., designed for reliable MCB (Miniature Circuit Breaker) housing in residential, commercial, and light industrial applications.

Unlike standard plastic-only boxes, the TSM series features a robust iron (steel) base that provides superior mechanical strength, grounding integrity, and long-term stability—especially critical when installing multiple breakers or in high-vibration environments. The outer shell is made of high-impact, flame-retardant ABS polymer, while the transparent PC (polycarbonate) cover allows instant visual inspection of breaker status without opening the panel.

Available in 8 circuit configurations (4, 6, 8, 12, 15, 18, 24, 36 poles) and two mounting types—Open-mounted (M) or Concealed-mounted (R)—the TSM box blends seamlessly into modern interiors. Standard color is white, but custom face-cover colors like dark green, brown, or ivory are available to match interior design schemes—combining functionality with elegance.

Rated for 63A continuous current and 10kA short-circuit making capacity, with an IP40 protection rating, the CDADA TSM distribution box ensures safe, organized, and future-ready electrical distribution.

Frequently Asked Questions

Q1: What’s the advantage of an TSM Iron Base Distribution Box vs. all-plastic distribution boxes?

A1: The iron base provides structural rigidity, prevents deformation during breaker insertion/removal, ensures better grounding continuity, and offers higher fire resistance—critical for safety compliance.

Q2: Is the transparent cover UV-resistant? Will it yellow over time?

A2: Yes. The cover is made of high-grade polycarbonate (PC) with UV stabilizers, ensuring no yellowing or brittleness even after years of indoor exposure.

Q3: Can I install this outdoors?

A3: No. With IP40 rating, it’s designed for indoor dry locations only. For outdoor or damp areas, use an IP65-rated enclosure.

Q4: Are busbars included?

A4: Standard models include a neutral and earth terminal block. Phase busbars (for MCB input) are optional accessories—available upon request.
