Reliable Protection for Industrial Systems

The DW15 630A Air Circuit Breaker (ACB) serves as a critical defense mechanism for heavy-duty electrical networks. Engineered to safeguard your infrastructure, it delivers a precise 630A rated current combined with a formidable 50kA breaking capacity at 415V. This ensures immediate interruption of abnormal currents, preventing catastrophic equipment damage. Beyond basic functionality, this unit is equipped with an intelligent release system that continuously monitors electrical flow. It provides multi-layered, accurate protection against overloads, undervoltage conditions, short-circuits, and single-phase grounding faults. By supporting advanced LSI/LSIG protection logic, the breaker allows facility managers to configure exact tripping thresholds, isolating faults effectively within complex low-voltage distribution networks.

Adaptable to Harsh Environments

Industrial facilities often present challenging atmospheric conditions, but this ACB is built to maintain consistent performance. It operates reliably in ambient temperature ranges from -5ºC to +40ºC and is fully capable of functioning at altitudes up to 2000m without derating issues. Furthermore, the internal components feature insulated housings and treated contacts to resist moisture, allowing the device to perform exceptionally well under up to 50% humidity at +40ºC. To accommodate different physical switchgear layouts, we offer both fixed and draw-out installation types. The draw-out configuration is particularly valuable for maintenance teams, allowing for rapid inspection and replacement without entirely dismantling the surrounding low-voltage distribution cabinet.

Advanced Accessories & System Integration

Modern power facilities require more than just manual switching. This circuit breaker supports a wide array of expansion modules to fit into automated grids:

• Motor Operating Mechanisms: Enables remote switching from centralized control rooms.

• Shunt Releases: Facilitates immediate emergency power-offs during critical facility events.

• Mechanical Interlocks: Prevents operational errors with a distinct physical lock-out mechanism in dual-power setups.

Certified Quality with Quick Customization

Compliance and reliability form the foundation of our manufacturing process. This ACB is strictly ISO 9001 and GSG certified, guaranteeing rigorous quality control at every assembly stage. It also fully complies with international electrical standards, including IEC60947-2 and GB14048.2, and is backed by CE and CCC certifications. For procurement teams requiring specific branding, KCISE offers custom logo samples and packaging samples in just 3 days. Once the design is approved, our streamlined production lines guarantee a fast 15-day lead time for bulk orders, ensuring your project timelines are met with absolute precision. We also provide all necessary clearance documents to facilitate smooth international transit.

Product Customization Process

Flexible Customization to Fit Your Needs

At KCISE, we offer a comprehensive product customization process tailored to the specific demands of international procurement teams. Whether you require a custom logo engraved on the breaker's front panel or unique packaging to align with your corporate identity, we collaborate closely to ensure the final product matches your exact branding requirements and technical specifications. Recognizing that heavy-duty electrical equipment requires superior protection during transit, we provide industrial-grade, heavy-duty custom wooden boxes. This specialized packaging absorbs shocks and vibrations, ensuring that the sensitive internal mechanisms remain completely undamaged during long-distance cross-border logistics and warehouse handling.

Quick Turnaround Time

We understand that speed is a critical factor in maintaining project schedules. To accelerate your decision-making process, we adhere to strict production timelines:

This rapid prototyping allows your engineering departments to physically review the designs without delaying the overall project. Following sample approval, our optimized manufacturing facility executes bulk orders efficiently, ensuring that large-scale installations receive their essential protective equipment exactly when needed.

Dedicated Support Throughout

From the initial technical inquiry to the final product delivery, our team provides clear communication and dedicated technical support. We assist buyers in selecting the appropriate protection logic and physical dimensions for their specific switchgear setups. Furthermore, we offer extensive trade and payment support to simplify international transactions. Buyers can utilize flexible payment terms such as T/T (Telegraphic Transfer) and L/C (Letter of Credit). To further optimize your procurement cycle, our logistics department actively assists in processing Certificates of Origin (such as Form A or Form E), significantly streamlining customs clearance and potentially reducing import duties for your shipment.

FAQs

What is the rated current of the DW15 630A Air Circuit Breaker?

The DW15 630A Air Circuit Breaker features a precise rated current of 630A. This specific capacity makes it an exceptional choice for acting as the main switch in low-voltage distribution networks. It is widely deployed across high-load industrial plants, large-scale commercial buildings, and municipal substations, providing a stable and continuous power supply while actively monitoring for any electrical anomalies that could disrupt daily operations.

What is the breaking capacity of the DW15 ACB?

This heavy-duty electrical component offers an impressive 50kA breaking capacity at 415V. In practical terms, this means the breaker can safely interrupt massive fault currents up to 50,000 amperes without sustaining internal damage or allowing the surge to pass through to downstream equipment. This provides incredibly effective short-circuit protection, preventing electrical fires and shielding expensive industrial machinery from catastrophic electrical spikes.

What environmental conditions can the DW15 630A ACB handle?

Designed for resilience, the DW15 630A ACB operates flawlessly in ambient temperatures ranging from -5ºC to +40ºC. It is also engineered to maintain its full protective capabilities at high elevations, supporting installations at altitudes up to 2000m. Additionally, the unit's insulated housing and treated contacts allow it to support up to 50% humidity at +40ºC, making it highly adaptable to non-climate-controlled industrial environments and outdoor substation enclosures.
