New Original Schneider A9N15656 Acti9 STI 3P 32A Fuse Disconnector
1. Product Overview
A9N15656 is an original Schneider Electric modular fuse disconnector from the premium Acti9 STI product range. It is a 3-pole DIN rail mountable integrated device that combines a safety isolating switch and standard cylindrical fuse holder, designed to accommodate 10.3 mm × 38 mm cartridge fuses. This component is specially developed for three-phase AC low-voltage power distribution circuits in industrial equipment cabinets, automation control panels, commercial power distribution systems, workshop machinery power loops and building auxiliary electrical installations. After installing gG general-purpose fuses or aM motor protection fuses inside each pole, the device can implement circuit isolation maintenance, overload protection and short-circuit fault cutting simultaneously. With unified modular specifications, it can be freely combined with miniature circuit breakers, residual current devices and contactors of the Acti9 series to build standardized low-voltage power distribution frameworks.
2. Main Functions
- Three-phase synchronous circuit isolation: The unified operating handle can cut off three live phases at the same time and form a visible physical breaking gap inside the device, complying with international electrical safety standards for power-off overhaul and equipment maintenance operations.
- Pole-by-pole overcurrent protection: Each independent pole is equipped with an individual fuse cavity; internal fuses will melt rapidly when overload or short-circuit faults occur on any phase, protecting downstream wiring, motors and electrical loads from burnout damage.
- Padlockable operating handle: The main toggle handle can be locked with padlocks at both ON and OFF positions to avoid unauthorized switching and prevent accidental power supply switching on site.
- Compatible fuse blow indicator: Reserved mounting positions for voltage indicator lamps on each pole. The lamp lights up to remind maintenance staff once a fuse is blown on any phase.
- Built-in spare fuse storage slot: An internal storage space is reserved for one spare cylindrical fuse, supporting quick on-site replacement without additional spare part preparation.
- Universal terminal wiring structure: Screw clamping terminals support both rigid solid copper wires and stranded flexible copper wires to adapt to diversified field wiring demands.
- Modular combined layout: Standard width design allows multiple disconnectors and other modular electrical appliances to be arranged side by side on 35 mm DIN rails for centralized circuit management.
