Feature: Three-pole design provides synchronized protection across all phases. Business Impact: Balanced current interruption prevents imbalanced faults that can harm motors and drives, reducing downtime. Application: Ideal for 208–240 V or 240 V three-phase motor circuits in pumps and conveyors. In practice, users see fewer nuisance trips during startup and improved component longevity. Feature: Plug-on mounting simplifies panel installation and service. Business Impact: Reduces field wiring errors and speeds changeouts, cutting commissioning time by hours. Application: Compatible with standard DIN rail-compatible panels and Eaton CH enclosures. Field technicians report tighter terminal finishes and consistent torque with plug-on modules. Feature: Neutral switching provides control circuit protection and eliminates neutral carryover during fault conditions. Business Impact: Improves safety and reliability for control logic and sensors. Application: Suitable for HVAC controls, pumps, and mixed-load panels where neutral switching is required. This capability supports safer startup sequences and reduced arc-flash exposure. Feature: Wire size compatibility #10-1/0 AWG Cu/Al at 60°C or 75°C. Business Impact: Enables flexible wiring strategies and supports modern copper or aluminum conductors without rewiring. Application: Retrofit and new-install projects in industrial facilities with diverse wiring practices. The CHF350SW accommodates common conductor sizes in control panels, reducing inventory needs. This compatibility supports code-compliant terminations and lowers project risk. Feature: HACR rated and UL Listed compliance. Business Impact: Meets electrical codes and enhances energy efficiency objectives while reducing downtime. Application: HVAC/R and general purpose industrial systems benefit from validated safety and reliability. Feature: Compact dimensions and warranty. Business Impact: Saves cabinet space, reduces shipping and inventory costs, and simplifies replacements. Application: Ideal for dense panels and modular installations in manufacturing and process environments.
