FAQs
Install the CHF110 as a single-pole protection device in a CH Loadcenter, ensuring one 2/4-inch space is available for the CHF frame. Use copper or aluminum conductors sized #14-8 AWG and #14-10 AWG as specified, terminate per torque recommendations, and confirm the trip flag operates after a fault to verify status during commissioning.
The CHF110 provides a 10 A current rating with a 10 kAIC interrupt capacity, operates at 120/240 V, is single-pole, and uses a Type CHF 3/4-Inch standard format. It is HACR rated and UL 489 listed, suitable for CH Loadcenters and a range of small-circuit protections.
Yes. CHF110 is HACR rated, which means it is approved for HVAC and other motor-load applications. This reduces the chance of nuisance tripping when starting motors and helps maintain code-compliant protection in load centers that serve heating, ventilation, and air conditioning equipment.
CHF110 carries UL 489 certification for circuit-breaker safety and performance. It is HACR rated for HVAC-related loads, enabling safer operation in systems with motors and heat-producing equipment while meeting relevant electrical standards.
