The SIEHFC263 Siemens 2PH 100A Fused Disconnect NEMA 3R offers reliable protection and control for electrical systems. Designed for outdoor and indoor use, this durable unit is weather-resistant and ideal for utility applications. With a 100-amp rating, it ensures optimal safety and performance for your electrical installations.
The Siemens HFC series 100A fused disconnect is designed to accept Class R (or equivalent) fuses up to 100A. The specific fuse type accepted — such as Class RK1 or RK5 — should be confirmed against the unit's interior label and your local electrical code requirements. Our team can help you select the correct fuse for your application.
The NEMA 3R rating makes this disconnect suitable for outdoor service entrance applications, and many HFC series units carry CSA/UL listings appropriate for Canadian installations. However, suitability as a main service entrance disconnect depends on your local utility requirements and the Canadian Electrical Code (CEC) rules for your province. We recommend confirming the unit's markings and your authority having jurisdiction (AHJ) requirements before installation.
