Space-efficient CHF 3/4-inch footprint frees panel real estate and simplifies retrofits in CH load centers, enabling faster wiring and reduced enclosure depth. This translates to lower labor costs and easier expansions in commercial electrical rooms. The single-pole CHF design streamlines wiring, decreases component count, and minimizes potential miswiring in 120/240 V circuits, improving installation speed and reliability for new builds and upgrades. With a 10 kAIC interrupt rating and a 120/240 V rating, it delivers robust short-circuit protection while limiting fault energy to downstream devices, supporting safer operation in demanding environments. Fire alarm red handle with trip indication provides immediate fault visibility, speeding diagnostics and enhancing emergency response in critical facilities. Compatibility with Type CH load centers ensures straightforward substitution in existing panels, reducing downtime. The unit accepts conductors sized as (2) #14-10 AWG Cu/Al and (1) #14-8 AWG, aligning with common wiring practices in modern electrical rooms.
