Key Features and Benefits

• Sensitive Ground Fault Protection: Detects leakage currents down to 5 mA to prevent electrical shock and reduce fire risk.
• High Interrupting Capacity: Rated at 10 kiloamperes interrupting capacity (10 kAIC), giving strong protection in case of large fault currents.
• Thermal‑Magnetic Trip Mechanism: Dual protection — thermal overload for sustained heavy loads, magnetic trip for sudden short circuits.
• Quicklag Design for Fast Response: The Quicklag technology ensures fast, reliable reaction to faults—especially helpful in industrial environments.
• Compact, Easy to Install: Measures approximately 5.6" × 4.5" × 3"; lightweight (around 0.9 lb) and bolt‑on mounting helps simplify panel integration.
