Recommended Fuse3: Series: Littelfuse p/n 313 2.5HXP, 2.5A 250V, slow blow, ¼ x 1 ¼ or, Cooper Bussmann p/n BKMDL-2½, 2.5A 250V, ¼ x 1 ¼ Parallel: Littelfuse p/n 313 5.0HXP, 5A 250V, slow blow, ¼ x 1 ¼ or, Cooper Bussmann p/n BKMDL-5, 5A 250V, ¼ x 1 ¼ Picture for Illustration Purposes only Construction: Dual bobbin construction with an insulated shroud, both made of a high temperature material that exceeds UL flammability requirements. Safety: Since the dual bobbin construction effectively reduces capacitance, electrostatic shielding is not required. World Series Transformers are designed and manufactured to meet the following agency approvals: Agency File: UL: File E53148, UL 5085-1 and 2 (formerly UL 506), General Purpose.
