Product Overview:
The L&T AU Series RCBO combines overcurrent protection (MCB) and earth leakage protection (RCCB) in a single device. This 25A, 4 Pole (3P+N) RCBO is designed for 415V AC systems with a high breaking capacity of 10kA. The 300mA sensitivity ensures protection against electrical leakage, while the C Curve is ideal for moderate inrush current applications like lighting and general home/industrial circuits.
Applications:
- Commercial buildings
- Industrial control panels
- HVAC systems
- Three-phase motor circuits
- Electrical distribution boards
