Overview
The DF2JA1311 is a Schneider TeSys GS DIN NH2 blade fuse, order code DF2JA1311, rated 690 VAC and 315 A with an aM (motor-protection) curve, supplied as a set of three fuses without striker.
The aM fuse curve is designed for motor-circuit protection — it withstands the inrush current of a starting motor and clears on a sustained overload or short circuit. The 315 A rating and 690 VAC voltage class suit it for large motor feeders, transformer primaries, or bus couplers in industrial switchboards.
Applications
TeSys GS DIN fuses are used in motor switch-disconnectors and protection relays within industrial control panels — typically on the line side of a contactor or soft starter for branch-circuit protection. The NH2 blade size fits standard DIN NH fuse holders and switch-disconnectors common in European-style distribution boards.
