10/5/22, 9:00 AM Isolation - Step Down (230VAC to 115VAC) (172 Series) - Hammond Mfg. Quality Products. Service Excellence. Isolation - Step Down (230VAC to 115VAC) 172 Series Plug-In Features Primary 230VAC, 50/60 Hz. Secondary 115VAC Circuit breaker in primary. Provides circuit isolation & steps down primary voltage. Hi-pot tested to 2 KV RMS. Electrostatic shield between primary & secondary. Input (primary) connected to a 5 foot long cord & European (Schuko) grounded plug - NOTE: old inventory only. Input - due to U.L changes in 2007 - NEW production with the European (Shuko) parts would no longer be U.L. listed. Therefore, we have replaced this input plug with a standard North American 3-wire, 250V plug (NEMA 6-15P).   Output (secondary) connected to a 1 foot long cord & standard North American 3-wire grounded receptacle (NEMA 5-15R). North American Mark of Safety - C UL & UL listed (File #E211544). Indoor use only.
