70A rating provides targeted protection for standard loads in 120/240 V systems, delivering reliable performance without encouraging nuisance trips during routine motor starts and loading fluctuations. This selective protection minimizes outages while safeguarding critical equipment, enabling smoother production runs in automation panels and distributed control architectures. 42 kAIC interrupt rating enables robust fault current protection for demanding installations, reducing potential equipment damage and shortening downtime after short-circuit events. This level of interrupt capability supports resilience in harsh industrial environments, where energy levels and motor inrush can challenge standard protection schemes. Bolt-on mounting speeds field installation and simplifies retrofits, helping technicians avoid costly alignment errors and reduce commissioning time in busy electrical rooms. The secure mechanical attachment also improves vibration resistance in factory floors and outdoor installations where equipment is exposed to dynamic loads. Two-pole configuration protects both hot legs, enabling reliable 120/240 V operation and safe handling of multi-wire circuits across single-phase and three-phase systems. This arrangement reduces wiring complexity, supports consistent protection across phase pairs, and simplifies panel planning for large industrial electrical loads. Designed for use with 37MM and 37SS modular metering stacks, CHH2070H4X integrates into Eaton's protection ecosystem with minimal interface issues and predictable spare parts compatibility. Compatibility lowers integration risk, accelerates project timelines, and helps maintenance teams manage inventories in facilities with mixed Eaton protection devices. UL 489 certification confirms compliance with recognized safety standards, reinforcing confidence during audits and inspections in regulated industries like food, pharma, and manufacturing. Coupled with a limited lifetime warranty, the product offers predictable long-term cost of ownership, service planning, and reduced total cost of ownership for asset-intensive operations.
