RUMF33F7 is a plug-in universal relay with three changeover (3 C/O) contacts rated 10 A at 277 V AC (UL/CSA) and 10 A at 250 V AC (NO, IEC). The coil is 120 V AC, 50/60 Hz, drawing 3 VA at 60 Hz. AgNi contacts handle 2500 VA / 280 W maximum switching capacity. Dielectric strength: 2500 V AC between coil and contact (reinforced), 1500 V AC between contacts (micro-disconnection). Meets pollution degree 3, IP40 protection, and can operate in any position. Holds approvals for UL 508, CSA C22.2 No 14, and IEC 61810-1—suitable for both North American and international control panels.
