Yes, all breakers have an insulation factor as to the maximum amount of voltage the device can be subjected to. A 208 volt breaker has a maximum up to and including 240 volts. A 480 volt breaker has a maximum up to and including 600 volts. A higher voltage rating breaker can be used on lower voltages but not the other way around.
what is the difference between miniature circuit breaker and fuse
A vacuum breaker does not allow back flow into the potable water system A syphon breaker is normallly installed on a tank that there is a possibility of the tank imploding
The amperage capacity of the main bus bars and the connection of the main breaker to the bus bars.
The difference between 16A TP and 16A TPN isolator is the type of the circuit breaker that is used. The terminal design is the other difference.
The connection blades and how they connect into the distribution panel's bus.
I can only assume that you are attempting to connect 480VAC coil from a elevator to a fire system in order to shunt the elevator. In order to do this you will need a shunt trip breaker rated for this use.
They are the same.
The energy dissipated.
VCB (vacuum circuit breaker) is used in HV (high voltage) applications. ACB (air circuit breaker) is used in LV (low votage) applications.
The main difference between MCB, RCCB, and Isolators Isolators are generally used in power system while on the other hand, MCB is the circuit breaker. Isolators are manually-operated device, and on the contrary, the circuit breaker is the automatically-operated device.
A single pole breaker controls one hot wire and is used for 120-volt circuits, while a double pole breaker controls two hot wires and is used for 240-volt circuits.
MCB stands for miniature circuit breaker , which provides protection against over current. the setting is not adjustable. RCB stands for residual circuit breaker which provides protection against earth fault as well as over current. It monitors the current difference between phase and neutral and if the difference is more than rated value say 200 milli amps it will trip.
