FAQs
CHP18B100R fits standard CH main breaker loadcenters with 18 spaces and 36 circuits and uses overhead feed. Check panel mounting for a compatible enclosure (NEMA 3R metallic) and confirm space for up to six service disconnects. Verify the CH bus and lug arrangement aligns with copper bus construction, and install with the included cover to meet code and minimize wiring errors.
The CHP18B100R uses a 100 A CH-type main breaker to provide reliable overcurrent protection for a single-phase 120/240 V system. The copper bus ensures low resistance and consistent current distribution across all 36 circuits. UL 67 and UL 50 listings support regulatory compliance for standard service equipment installations in commercial and light industrial settings.
Yes. The unit features a NEMA 3R metallic enclosure with rainproof hub options and a cover included, enabling outdoor and damp-location installations. UL listings and the weather-resistant design help ensure durable service equipment in challenging environments, meeting code requirements for exposed electrical spaces.
Eaton provides a limited lifetime warranty on CH series loadcenters. Maintenance generally involves routine inspection of connections, bus integrity, and labeling. The rugged metallic enclosure and copper bus reduce corrosion risk and replacement frequency, supporting lower lifecycle costs and predictable asset performance for facilities with ongoing electrical infrastructure needs.
The CHP18B100R consolidates protection and expansion in a single enclosure, reducing panel upgrades as loads grow and lowering retrofit costs. Its durable hardware, UL-listed protection, and included cover streamline installation, leading to shorter commissioning times and fewer field-service calls. Over time, this translates to improved reliability and more predictable maintenance budgeting for industrial facilities.
