YCB7NLE-125 RCBO Electronic

The YCB7NLE-125 RCBO Electronic is a high-performance residual current circuit breaker designed for final distribution applications. It offers rated currents of 63A, 80A, and 100A, with exceptional features including high flame retardancy, temperature resistance, and impact resistance.

Boasting a short-circuit breaking capacity of 6000A, it ensures reliable protection against overloads and short circuits for cables and lines, while also providing personnel and fire protection

Product Details

General

1. Personnel and fire protection

2. Cable and line protection against overload and short-circuits

Selection

1. IΔn ≤ 30 mA: additional protection in the case of direct contact.

2. lΔn ≤300 mA: preventative fire protection in the case of ground fault currents.

3. lΔn class - Tripping is ensured for sinusoidal, alternating currents, whether they be quickly applied or slowly increase.
