FAQ

What type of fuses are compatible with the Schneider 15656?
This disconnector is designed for cylindrical industrial fuses of size 10.3 x 38 mm. It is compatible with both gG type fuses up to 32A and aM (motor protection) type fuses up to 25A.

Can this fuse disconnector be used in a 3-phase system?
Yes, as a 3-pole (3P) device, it is specifically designed for use in three-phase electrical systems to provide simultaneous disconnection and protection for all three phases.

What is the breaking capacity of this device?
The breaking capacity is determined by the installed fuse, not the holder itself. The holder is rated according to IEC 60947-3 for isolation purposes. You must select a 10.3x38mm fuse with an appropriate breaking capacity (e.g., 20 kA, 100 kA) for your specific application’s short-circuit current level.
