FERRAZ SHAWMUT OT15 fuses are versatile, general-purpose fuses providing economical protection for feeder and branch circuits. These fuses are ideal for lighting, heating, and other non-inductive loads, offering a high interrupting capacity of up to 50,000 amperes. They are not rejection fuses, requiring careful replacement with fuses of equal or greater interrupting ratings. The OTN series specifically satisfies Canadian electrical code requirements for Type “P” low melting-point, non-time-delay fuses. Applications include residential and small commercial installations where reliable and cost-effective circuit protection is needed.
