Siemens HF261 Heavy Duty Safety Switch Type 1

Siemens HF261 Heavy Duty Safety Switch Type 1 is a 30 A, 600 V indoor fusible safety switch configured as two poles with two wires (2P2W) in the VBII family. It uses a Type 1 (NEMA 1) indoor enclosure designed for surface mounting with lug terminals, making it suitable for installations within standard indoor panels and switchgear in industrial or commercial settings. The unit measures approximately 14.26 in high, 7.67 in wide, and 10.17 in deep, and operates over a temperature range of -29°C to 85°C, accommodating a broad range of indoor environments. Optional auxiliary contact kits are available to support signaling and interlock needs, including HA161234 (one normally open and normally closed) and HA261234 (two normally open and normally closed). This HF261 model provides reliable isolation for small motor circuits and feeders within a 600 V system, delivering a compact, heavy‑duty disconnect solution with a two‑pole, two‑wire configuration in a sturdy indoor enclosure.
