Feature: 175A amperage rating paired with 600 Vac / 600 Vdc voltage capability. Business impact: supports heavy-load applications while maintaining safe insulation and flexible operation across AC and DC systems. Application: motor control panels and mixed-voltage power distributions where both AC and DC supply rails are present. Feature: Three-pole design with a 10 kAIC short-circuit rating (SCCR). Business impact: enhances fault tolerance, reduces risk of accidental arc-flash events, and eases panel design with higher fault isolation. Application: centralized distribution in industrial control cabinets where multiple feeds converge. Feature: Molded thermoplastic housing in black. Business impact: provides durable insulation, lower weight for easier handling, and resistance to typical shop-floor conditions. Application: compact control panels where space and thermal performance matter. Feature: Compact dimensions and lightweight profile (5.37 in L × 2.8 in W × 2.12 in H; 0.75 lb). Business impact: minimizes enclosure footprint and simplifies rack or cabinet layouts, reducing installation time and materials. Application: retrofit projects and new builds seeking efficient footprint utilization. Feature: RoHS compliant with Certifications available from the manufacturer. Business impact: streamlines regulatory documentation and supplier qualification for global operations. Application: procurement, quality audits, and compliance packages across facilities. Feature: Part of Eaton Bussmann series power distribution blocks. Business impact: ensures proven interoperability with other Bussmann components, lowers total cost of ownership, and simplifies stocking of common spares. Application: multi-block power distribution schemes in panel assemblies and power centers.

FAQs
Begin by verifying the panel's space and conductor sizes align with the block's 175A rating. Prepare conductors for clean terminations, secure the block in the enclosure, and connect incoming and outgoing conductors per the panel's wiring diagram. Ensure proper torque on terminals and observe clearance for cooling and maintenance.
The 16021-3 is rated for 175A with voltage ratings of 600 Vac and 600 Vdc, and an SCCR of 10 kAIC. These ratings enable robust fault protection and suitability for heavy-duty control and power distribution applications in industrial environments.
Yes. The specification identifies it as a three-pole power distribution block, providing balanced distribution across three phases and simplifying wiring schemes in three-phase control panels and motor control centers.
The product is RoHS compliant, and certifications are listed as 'Contact Manufacturer' for formal documentation. For CE, SIL, or IP-related certifications, consult Eaton directly to obtain the official paperwork and approval status relevant to your region and application.
The block's compact, lightweight design reduces installation time and enclosure space, while the high SCCR and durable molded thermoplastic housing lower long-term maintenance and replacement costs. Standardization with Eaton Bussmann series simplifies spares management and procurement, contributing to lower lifecycle total cost of ownership.
