Frame Size 125 leakage rack MCCB assembly
product description
The brackets are primarily used as structural supports to securely mount and align the various components of the MCCB, including trip units, contacts and arc extinguishing systems. Their precise placement ensures that mechanical forces, especially those generated during short circuit events, are effectively managed and dissipated, preventing damage to the circuit breaker or surrounding equipment.
Additionally, brackets play a vital role in maintaining clearances and creepage distances, which are critical safety aspects. The brackets help MCCBs comply with international safety standards by keeping live parts at a safe distance from grounded metal parts and ensuring insulation integrity, thereby preventing electrical faults and arcing.
In terms of thermal management, brackets often promote heat dissipation by directly contacting heating components or providing air flow ducts, thereby improving the thermal performance and service life of molded case circuit breakers.
Finally, the material selection and design of the bracket are also critical. Choose durable materials that are corrosion-resistant and can withstand working stress to ensure that the molded case circuit breaker operates reliably under different environmental conditions.
In summary, brackets, while an inconspicuous element in the complex architecture of MCCBs, are integral to structural integrity, safety compliance, thermal efficiency and long-term reliability, making them an important element in the design of these protective Ideal for installations and important considerations. manufacturing.
