Key Features

Precision Protection Characteristics

• Type B Tripping Curve: Delivers fast short‑circuit tripping (5×In to 10×In) and stable overload protection, ideal for sensitive electronics, lighting, and control circuits.
• Dual Trip Mechanisms: Thermal trip for gradual overloads and electromechanical trip for instantaneous short‑circuit interruption, ensuring comprehensive protection.
• Current Limiting Technology: Reduces fault current magnitude and arc duration, minimizing damage to wiring and connected equipment.

Robust Electrical Performance

• High Breaking Capacity: 50 kA AC breaking capacity handles severe fault conditions in industrial and commercial environments.
• AC/DC Compatibility: Supports 250 V DC applications, making it suitable for solar PV systems, battery backups, and DC control circuits.
• Galvanic Isolation: Full isolation between poles and housing prevents cross‑conductance and enhances safety.
