New Original Schneider A9N15636 Acti9 STI 1P 25A Fuse Disconnector
1. Product Overview
The A9N15636 is an original Schneider Electric modular STI series fuse disconnector under the premium Acti9 low-voltage distribution product line. It is a 1-pole DIN rail-mounted fuse holder integrated with an isolating switch, designed to accommodate standard cylindrical cartridge fuses with dimensions 10.3 mm × 38 mm. This unit combines three core functions: manual circuit isolation, fuse mounting carrier, and overload/short-circuit protection triggered by inserted gG general-purpose fuses or aM motor-protection fuses. Widely deployed in industrial control cabinets, commercial power distribution systems, machinery automation panels, building auxiliary electrical circuits and tertiary facility power loops, it delivers reliable circuit cut-off capability for equipment maintenance and safeguards downstream electrical loads against overcurrent faults. The standardized modular structure ensures seamless combination with other Acti9 series low-voltage components inside distribution boxesSchneider ….
2. Main Functions
- Genuine Electrical Isolation Function: The front operating toggle can fully disconnect the live circuit to form a visible break point, complying with international isolation safety standards for safe power-off maintenance work.
- Fuse Carrier & Overcurrent Protection: Holds 10.3×38 mm cartridge fuses; inserted gG fuses protect general circuits from overload and short-circuit faults, while aM fuses provide short-circuit protection for motor loads with high starting current.
- Lockable Switch Toggle: The operating handle supports padlocking in both open and closed positions to prevent unauthorized switching operations on site.
- Fuse Blown Status Indication Compatibility: Reserved mounting space for optional 230V AC neon indicator lamp, which lights up red once the internal fuse melts to remind maintenance personnel of fault conditions.
- Spare Fuse Storage Slot: Built-in small cavity inside the housing for storing one spare cartridge fuse to facilitate rapid on-site replacement.
- Universal Cable Connection: Screw clamp terminals accept both rigid and flexible copper wires of various cross-sectional areas for flexible wiring layout.
- Modular Combination: Standard 18mm width module can be arranged side by side with multiple identical units or other Acti9 series electrical devices on 35mm DIN rails.
