Data graphed above are average values and should be verified in application. Tests were
conducted within a 2’ (.6m) cube (still air); at nominal coil power @ 25°C; with normally
open contact loaded; and with 4’ (1.22m) long, #10AWG load wires. P.C. board relays were
mounted to a 30A, single side P.C. board. Coil rise test conducted with a 30A PC board
to maintain 20°C max. rise at 30°C. The relay connections and wiring must be designed
with an adequate cross section to ensure proper current flow and heat dissipation. After
cleaning process knock-off nib should be removed for optimum life of wash-tight relays.
