UL891 Switchboards

KEY FEATURES

Power Distribution Center: UL891 Switchboards

As the heart of Power System, Switchboards is applied in Office building, Data center, Hospital and Industrial facilities to distribute power to terminal load. Its performance quality is related to building operation security of person.

UL 891 Standard is authoritative certification basis for Switchboards (Dead-Front Switchboard) in the North American Market. LV Switchboard compliance with UL891 signify its safety and reliability are rigorously verified. As UL Certification manufacturer, we have profound knowledge about UL Standard. We provide customer safe and reliable product, trustworthy long-term partner, and global market certification.

Outstanding Performance: UL891 Switchboards Core Characteristic

Compared with ordinary Switchboards, Switchboard compliance with UL 891 is equipped with outstanding quality in terms of safe, structure and performance. It provide customer following multiple value guarantee:

· Comprehensive Safety Protection(Dead-Front Design): UL891 Standard require to utilize “No Exposed Live Conductor” design. It signify busbar, terminal and live conductor are isolated by protective barriers or insulating boot to guarantee that operators will not accidentally contact with live parts under any circumstances.

· Firm Structural Strength: UL891 Standard propose definite requirement in mechanical strength, stiffness and electrical durability of steel structure and components. Our LV Switchboard is manufactured with high-quality steel and firm framework. It can withstand various mechanical stress during handling, installation and operation. This will guarantee structural integrity and stability throughout its life cycle.

· Outstanding Short-circuit Current Withstand: UL891 Standard require to verify Short-Circuit Current Rating. We verify our UL891 LV Switchboard can break peak short-circuit current to guarantee we provide customer qualified product.

· High-efficiency Temperature Rise Control: Implement thermal design and select high-quality conductive materials to control temperature rise compliance with UL891 Standard requirement, and guarantee reliability & service life of critical components during long-term operation.

· Flexible Configuration & Expansion: Under the premise of compliance with UL891 Standard, we accept customer to customize solution & design and reserve expansion space.

Challenge: UL891 Certification Difficulty

Continuously manufacturing UL891 LV Switchboard is a challenge of manufacture comprehensive competence. Following are primary difficulties.

1, Technical & Design Threshold

UL891 Standard have complicated and specific requirements in terms of structure, clearance and thermal properties. UL Standard comprehension and applying UL Standard in design require profound technical accumulation and UL certification experience. Any design deviation may lead to certification failure.

2, Rigorous Test and Certification Cost

Certification process require a series of destructive prototype test including but not limited short-circuit withstand test, temperature rise limit test. It requires accurate design, technical competence and forecast competence to guarantee test is one-pass.

3, Supply Chain Control

Each component from circuit breakers, isolating switches, busbar through to insulation material require equip with UL certification, compliance with model & specification requirement in UL files. Establishing and managing compliant supply chain requires resource integration capabilities and long-term accumulation.

4, Continuous Consistent Quality

UL Certification requires UL FUS (UL Follow-Up Services) proceed with inspection every year to inspect product life cycle including but not limited to material procurement, manufacturing and test. Our product life cycle adheres to quality management system to guarantee our quality and model of delivered switchboard is consistent with certified sample.
