A circuit breaker is like an automatic switch, designed to break a circuit if the current flowing (measured in amps) exceeds a predetermined maximum amount. The frequency at which the alternating current is changing is not relevant provided it is the normal one for which the circuit breaker has been designed to operate. In USA, Canada and other countries using similar power supply standards, that frequency is 60 Hz. In Europe and other world areas using similar power supply standards, that frequency is 50 Hz. A circuit breaker designed for use on 50 Hz or 60 Hz supplies should not be used to protect a circuit in a ship or aircraft running on a 400 Hz supply because its magnetic and capacitive components may not operate correctly. For such applications a circuit breaker designed to operate at 400 Hz must be used.

A breaker can work on both 60Hz and 50Hz supplies because the internal mechanical and electrical components are designed to operate within the range of frequencies encountered in different electrical systems. The design and construction of the breaker are optimized to handle varying frequencies without impacting its functionality or performance.
You can but it would be wise not to. Most 60hz appliances will not work at 50 Hz. <<>> Yes, no problem at all. The frequency does not enter into the equation because the hot plate is a strictly resistive load.
No, because if you switch a 50-amp load on, it will blow a 40-amp circuit breaker if the load exceeds 40 amps, which is likely.
No, a double pole 50 amp breaker protects a 240 volt supply at 50 amps. The number that is on the handle of the breaker is the amperage that the breaker will trip at if an overload occurs on the circuit.
For a 41 amp load, you would typically use a 50 amp circuit breaker. The general rule is to select a breaker size that is 125% of the continuous load amps or equal to the load amps if it is not a continuous load. In this case, 41 amps is considered a continuous load, so you would round up to the nearest available breaker size, which is 50 amps.
For a 12 Volt 50 watt light, you would need a 4.17 Amp breaker. To calculate this, you can use the formula Power (W) = Voltage (V) x Current (A), rearranged to find Current (A) = Power (W) / Voltage (V). So, 50 watts / 12 volts = 4.17 Amps.
