Siemens 3KA5340 Brand Introduction Siemens 3KA5340 is SENTRON series switch disconnector developed by Siemens for industrial low voltage power distribution system. It specializes in safe circuit isolation and power cut-off for electrical cabinets and automation equipment, providing visible break point for maintenance operation. Switch Disconnector is the core unit of Siemens 3KA5340. Switch Disconnector adopts 4-pole structure design with rated current 160A. Switch Disconnector supports rated voltage up to 690V AC. Switch Disconnector realizes reliable main circuit switching and electrical isolation. Siemens 3KA5340 provides stable Isolation for workshop power control cabinet. Isolation creates visible disconnection gap for equipment overhaul. Isolation meets IEC safety standard for low voltage power system. Isolation supports manual local operation with optional handle assembly. Siemens 3KA5340 features reliable Circuit for industrial power loop control. Circuit supports high load switching and long mechanical service life. Circuit is compatible with Siemens low voltage distribution components. Circuit protects downstream automation modules and motors during maintenance. Siemens 3KA5340 is widely used in machinery manufacturing, water treatment and legacy power cabinet renovation. With mature Siemens SENTRON low voltage technology, this disconnector works within temperature range -20~+60℃ and has strong anti-vibration performance. It provides full lifecycle technical support including wiring, commissioning and after-sales maintenance, serving global users as a trusted low voltage switch disconnector solution.
