The Schneider EA9L409F230 is a Miniature Circuit Breaker (MCB) designed for overcurrent protection in residential, commercial, and industrial electrical installations.
Parameters:
Rated Current (In): 9A
Poles: 4P (four-pole breaker, ideal for 3-phase circuits plus neutral)
Tripping Curve: C Curve (trips between 5 and 10 times the rated current, suitable for general-purpose circuits like lighting or small motors)
Rated Voltage (Un): 230/400V AC (for standard 3-phase electrical systems)
Rated Frequency: 50/60Hz
Breaking Capacity (Icn): 10kA (maximum fault current the breaker can handle without damage)
Insulation Resistance: ≥ 100MΩ (at 500V DC)
Overload Protection: Yes, provides protection against overload conditions by tripping when the current exceeds the rated value for a prolonged period.
Short Circuit Protection: Yes, trips instantly when a short circuit is detected, preventing damage to the system.
Ambient Temperature Range: -25°C to +60°C
Mechanical Durability: 20,000 operations
Electrical Durability: 4,000 operations (at rated current and short-circuit protection)
