Suitable for service entrance use with a neutral kit installed
The DT221URH is a 30 A general-duty double-throw safety switch with a fusible configuration. This design delivers precise current limiting and clean isolation, reducing arc energy and fault propagation in powered circuits. The business impact is measurable: faster fault isolation, improved equipment protection, and lower risk of cascaded outages. In practice, engineers deploy this switch in service entrances and control panels where predictable disconnects are essential for safe maintenance and startup sequencing. UL Listed certification is a critical risk mitigator, simplifying electrical code compliance and inspection processes. It provides confidence in safety margins, reduces audit findings, and supports standardized procurement across facilities. Applications include industrial automation panels and service entrances where robust protection and traceable safety credentials matter for reliability and regulatory alignment. Catalog Notes indicate suitability for service entrance use with a neutral kit installed, offering installation flexibility and fewer last-minute modifications. The neutral-kit capability simplifies code-compliant setups, while the switch’s compact footprint (9.88 in depth, 24.63 in height, 11.94 in width) and 34 lb weight ease handling and mounting in restricted enclosures. Compact dimensions and stable build translate to predictable field performance, minimizing replacement cycles and maintenance overhead—key for plant-wide reliability and cost control. Warranty and service support are backed by Eaton policies, helping stabilize long-term ownership costs. The 25-000 warranty covers one year from installation or 18 months from shipment, whichever occurs first, reducing lifecycle risk for procurement teams and end-users alike.

FAQs
DT221URH is designed for service entrances and control panels, featuring a compact footprint (9.88 in depth, 24.63 in height, 11.94 in width) and a 34 lb weight to ease handling. Ensure enclosure space accommodates the dimensions and that the neutral kit option is available if service entrance use is planned. The UL Listed rating supports code compliance during audits, simplifying procurement and installation decisions.
The 30 A fusible, double-throw configuration provides reliable isolation and current limiting, helping to confine fault energy and prevent fault propagation. This improves selectivity and reduces downtime during maintenance or fault events. In practice, use this switch in branch circuits and panel boards where predictable disconnects and safe maintenance sequencing are required.
Yes. The DT221URH is intended for service entrances and control panels in industrial environments. Catalog Notes confirm suitability for service entrance use with a neutral kit installed, enabling code-compliant setups without additional modifications. This enhances installation flexibility and reduces part counts while maintaining compliance with UL Listed safety standards.
The DT221URH carries UL Listed certification, a critical indicator of safety compliance for electrical equipment used in low-voltage distributions. This certification simplifies regulatory approvals, supports consistent performance expectations across facilities, and reduces risk during audits and inspections in industrial settings.
Warranty coverage for the DT221URH is Eaton Selling Policy 25-000: one year from installation or 18 months from shipment, whichever occurs first, which lowers lifecycle risk. The combination of robust protection, straightforward installation, and official datasheets supports reduced downtime and faster maintenance planning, delivering favorable total cost of ownership and predictable long-term reliability.
