The SDL7-63 miniature circuit breaker is suitable for AC 50/60Hz circuits with a rated voltage of 230/400V and a rated current up to 63A.
It provides overload and short-circuit protection and can also be used for infrequent switching of circuits under normal conditions.
The circuit breaker is applicable in various settings, including industrial, commercial, high-rise buildings, and residential areas.
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.
