SZR-LY Series
®
SZR-LY Series general-purpose power relays are designed for a wide
range of applications including power as well as logic control for factory
machines and control panels.
SZR-LY Series relays break 10 A loads and are ideal for control panels
that require stable and reliable relays.
One standard and three options are available: LED indicator, internal
surge protection diode, and LED indicator/diode protection. Honeywell’s
global sales and distribution channels ensure a rapid response and excellent
customer service.

Note 1: The rated current and coil resistance are measured at a coil temperature of 23 °C [73.4 °F] with tolerances of +15%,
-20% for AC rated current and ± 15% for DC coil resistance.
Note 2: The rated current of N1 and X1 types is 4 mA higher than the value in the table above.
