Struthers-Dunn 415XBX Relay 120V AC SPDT NO NC Contacts

The Struthers-Dunn 415XBX is a compact, base-mounted DPDT industrial relay designed for 120 VAC coil operation and capable of switching up to 15 A at 120/240 VAC resistive loads. It uses a DPDT (XBX) contact arrangement, providing two Form-C (NO/NC) contacts with screw terminals as standard, a nominal coil power of 6 VA at 120 VAC, and operate/release times of about 25 ms and 10 ms respectively. Electrical life is rated at around 200,000 full‑load cycles and mechanical life near 20,000,000 cycles, with 1,000 Vrms dielectric strength across open contacts and 1,500 Vrms between mutually insulated points, plus insulation resistance of at least 1,000 MΩ at 500 VDC. The unit tolerates AC coil voltage from 85% to 110% of nominal and DC from 80% to 110%, operates from −40 to 55 °C (AC) or −40 to 70 °C (DC), stores from −40 to 105 °C, and weighs about 4 oz (113 g); it is UL Recognized and UL Listed, features an open enclosure, and a vertical-contacts-up mounting orientation for straightforward panel or base installation.
