The SDC86 is a new generation of products from Sincede. It is designed for AC circuits with a frequency of 50Hz/60Hz, a rated voltage of up to 240V, and a rated current of up to 80A. This circuit breaker provides reliable protection against line overload and short circuits.
With its advanced structure, strong breaking capacity, and compact, attractive design, the SDC86 is widely used in industrial, commercial, high-rise, and residential settings.
The SDC86 meets the standards of IEC/EN 60898-1 and IEC/EN 60947-2.
1. The Miniature Circuit Breaker (MCB) is made for people without technical training to use safely, and it doesn’t need maintenance.
2. In the situations mentioned, an MCB with an “ON-OFF” indicator can be used for isolation.
3. It’s recommended to install protective devices like surge protectors or surge arresters before the MCB to prevent damage from surge voltages or currents that may occur at the power input.
4. If the correct tripping curve is chosen and the MCB is properly installed, it will trip and turn off the circuit in case of a fault, providing protection from electric shock.
