Why Choose CDADA Compact MCCB?

★ Various accessories are optional,

★ Size is greatly reduced.

DAM3, which integrates all the features of high quality, high reliability and simplicity of Dada electric, is a real simple and practical Molded Case Circuit Breaker.

The size is reduced, but ensures excellent performance and reliability. Compared with all similar circuit breaker products on the market, it has high performance dimension ratio., which can provide more space for users to conduct cable wiring and reduce the size of cabinet.

Compact size has great advantages. It is especially suitable for OEM factories, panel factories, and installation workers.

★ Simplified Procurement & Installation

● Clear model coding → easy ordering

● Standardized accessories → no custom parts needed

● Generous terminal access → faster cable termination

★ Cost & Space Savings 

Smaller breakers = smaller enclosures = lower material, shipping, and installation costs. Extra internal space also improves heat dissipation and maintenance access.

★ Proven Reliability 

Built on decades of DADA engineering experience. Shares core components with the field-proven DAM1 series—trusted in thousands of installations worldwide.

★ Scalable Across Applications 

From a 32A mini MCCB for control circuits to a 1600A main breaker for industrial feeders—the DAM3 platform covers it all with consistent design logic.

Ideal Use Cases

★ OEM Machinery: Embed in compact control cabinets (e.g., packaging, CNC, robotics)

★ Commercial Panels: Lighting, HVAC, and sub-distribution in high-rises

★ Renewable Energy: Solar combiner boxes & inverter protection

★ Infrastructure: Telecom power units, EV charging stations

★ Retrofit Projects: Replace bulky legacy breakers without redesigning panels

FAQs

Q1: What makes the DAM3 a “compact” MCCB?

A1: Its mechanical design is 25–30% smaller than standard MCCBs in the same current range—achieved through optimized arc chambers, compact trip units, and efficient busbar routing—while maintaining full 70kA breaking capacity.

Q2: Is the 32A compact MCCB available in 3-pole?

A2: Yes! The DAM3 series Compact Moulded Case Circuit Breaker offers 2P, 3P, and 4P configurations across the entire 16A–1600A range, including popular ratings like 32A, 63A, 100A, and 160A.

Q3: Can I use the same accessories as DAM1?

A3: Absolutely—all internal and external accessories (shunt trips, auxiliary contacts, undervoltage releases, etc.) are fully compatible with the DAM1 series, simplifying inventory.

Q4: Does compact size affect breaking performance?

A4: No. Despite its small size, DAM3 delivers up to 70kA interrupting capacity at 415V—exceeding many larger competitors—thanks to advanced arc-quenching technology.

Q5: Why choose CDADA over other “mini” MCCB brands?

A5: CDADA stands out because:

● True high-current coverage (up to 1600A in compact form)

● 70kA breaking capacity in select models (rare for “mini” MCCBs)

● Full accessory ecosystem and DAM1 compatibility

● Global compliance focus (IEC, CE, RoHS)

● OEM-focused support: English documentation, fast sampling, bulk pricing
