Siemens I-T-E FR353 Heavy Duty Safety Switch 100A 600V 3P Non-Fusible NEMA 3R

The Siemens I-T-E FR353 is a heavy-duty enclosed safety switch designed for reliable disconnection and protection in industrial and commercial electrical systems. This non-fusible, 3-pole switch is rated for 100 amperes and up to 600 volts, making it suitable for applications requiring high-power isolation, such as motor controls, machinery, and service entrances. Housed in a NEMA 3R enclosure, it provides weatherproof protection for outdoor installations, resisting rain, sleet, and external ice formation. Key features include visible blade double-break switching action for enhanced safety, padlockable handle for lockout/tagout compliance, and robust construction for durability in harsh environments. Advantages over similar products include Siemens' reputation for reliability, easy installation with generous wiring space, and compliance with UL 98 standards. Benefits include improved safety by preventing accidental energization and quick disconnection during maintenance. Drawbacks may include its larger size compared to compact alternatives and the need for separate fusing if overcurrent protection is required. Ideal for manufacturing plants, utilities, and agricultural settings, this switch ensures efficient power management while minimizing downtime. Based on images, the unit appears used with minor cosmetic wear but intact internals, no visible damage to components.
