Features and benefits:

• Thermomagnetic release combines overload and short-circuit protection in one compact three-pole unit
• 36 kA breaking capacity at 400/415 V meets demanding industrial distribution and motor protection requirements
• Adjustable Ir (63-80 A) and Ii (480-800 A) settings enable precise coordination with upstream and downstream devices
• Sub-10 ms break time limits let-through energy and reduces stress on downstream equipment during fault events
• Dual mounting via DIN rail or fixed built-in technique suits panel board and switchgear assembly alike

Applications:

• Motor circuit protection in industrial machinery operating at up to 690 V AC
• Power distribution in unearthed (IT) supply systems
• Cable and feeder protection in commercial and industrial switchgear panels
• Pump, fan, and compressor control cabinets requiring 80 A rated protection
