The Schneider ISCB2 120L2 4P is a Molded Case Circuit Breaker (MCCB) designed to provide overcurrent protection for electrical circuits. It is part of Schneider Electric's ISCB2 series, which offers high-performance protection for industrial and commercial applications
Parameters:
Rated Current (In): 120A
Poles: 4P (4-pole design, typically used for 3-phase systems with neutral protection)
Rated Voltage (Un): 400V AC (common voltage for industrial 3-phase circuits)
Rated Frequency: 50/60Hz
Breaking Capacity (Icu): 50kA (maximum fault current the breaker can safely interrupt without causing damage)
Overload Protection: Yes, provides thermal overload protection for circuits, ensuring the breaker trips if the current exceeds the rated value for an extended period.
Short Circuit Protection: Yes, provides magnetic short-circuit protection, allowing the breaker to trip instantaneously during short circuit conditions.
Insulation Resistance: ≥ 100MΩ (at 500V DC)
Mechanical Durability: 20,000 operations
Electrical Durability: 10,000 operations (under rated current and short-circuit conditions)
Auxiliary Contacts: Available for signaling and monitoring purposes.
Operating Temperature: -25°C to +70°C (suitable for a wide range of operational environments).
