Introducing the Nader Shanghai Liangxin NDB1C-125 Series Circuit Breaker Air Switch
For electrical engineers, contractors, and facility managers seeking reliable circuit protection solutions, the NDB1C-125 Series from Nader Shanghai Liangxin offers robust performance in diverse applications. This DIN-rail mounted miniature circuit breaker combines precision engineering with rigorous quality control to deliver stable overcurrent and short-circuit protection for residential, commercialFrame Rating**: 125A
- Poles: Available in 1P, 2P, 3P, or 4P configurations
- Current Ratings: 50A, 63A, 80A, 100A, 125A
- Breaking Capacity: High interrupting capability (Complies with IEC/EN 60898 and IEC/EN 60947-2)
- Voltage Rating: AC 230/400V
Core Advantages
- Selective Tripping: Thermal-magnetic technology ensures accurate disconnection during overloads (thermal protection) and short circuits (magnetic).
- Modular Design: Compact form factor allows for simplified installation and compatibility with standard distribution boards (DIN rail mount).
- High Durability: Flame-retardant thermoplastic housings with copper alloy terminals minimize oxidation and extend service life.
- Visual Status Indication: Clear ON/OFF toggle positions with integrated red/green markers for at-a-glance circuit status.
Application Scenarios
Suitable for mains distribution, motor control centers, HVAC systems, and lighting circuits. The 4P variants (e.g., 100A 4P) provide comprehensive neutral phase protection in three-phase environments, while 1P units (e.g., 63A 1P) streamlineated manufacturing ensures adherence to RoHS directives. Each unit undergoes dielectric strength and temperature-rise testing, validated by global certifications including CE, CCC, and TÜV.
Engineer's Note: Specify amperage according to cable cross-section and load calculations per IEEE or local electrical codes. For 4P-TPN configurations in transformer-connected systems, consult the included torque specifications when terminating ≥16mm² conductors.
