RCBO – Modular DIN Rail Products

RCBO – Modular DIN Rail Products (NP1LE Series) combines residual current protection with overload and short-circuit protection in a single compact device. Designed for AC 50/60Hz systems with rated voltage up to AC 400/415V and current up to 80A, it ensures reliable protection against electric shock, leakage faults, and line overcurrent conditions.

The NP1LE series integrates leakage, overload, and short-circuit protection, with optional customization for over-voltage protection and adjustable leakage action current. Its modular DIN rail design allows quick installation and efficient space utilization in distribution boards.

Ideal for residential distribution panels, commercial buildings, industrial control cabinets, and power distribution systems, the NP1LE RCBO enhances electrical safety, improves system reliability, and reduces installation complexity.
