• Well suited for various industrial, commercial and residential applications,
as well as many others.
Typical Coil Temperature Rise
Data below are average values and should be verified in application. Tests
were conducted within a 2’ (.6 m) cube (still air) with relay mounted to a
30A, single side P.C. board (6); at nominal coil power @ 25°C; with normally
open contact loaded; and with 4’ (1.22 m) long, #10 AWG load wires.

Notes
(1) Operating ambient temperature must consider “Must Operate Voltage Change
Over Temperature,” Contact Temperature Rise, Coil Temperature Rise (If coil
is not allowed to cool) and Maximum Coil Temperature. Specification ambient
considers nominal coil voltage, 20A load with coil cooled to ambient.
(2) Sealed relay terminals should not be bent.
(3) Knock-off nib should be removed after cleaning process for optimum life of
sealed relays.
(4) Maximum soldering temperature is 500°F for 4 seconds.
(5) Class F coils are UL systems approved for maximum coil temperature of
155°C by change of resistance method.
(6) See application note 13C265 for proper relay mounting, termination, cleaning
and PC board conductor width. Coil rise test performed with 30A PC board to
maintain 20°C maximum rise @ 30A.

Optional plastic dust cover is a snap-on unit, open on the PC board side of
the relay. The cover, when ordered with the relay, is shipped separately. It
is designed to be snapped into place by the customer after the relay has
been assembled to the PC board.
