What is a DS circuit breaker?
Background. Westinghouse DS circuit breakers are designed specifically for use in metal enclosed low-voltage switchgear assemblies used at system voltages up to 600 VAC.
What is a B40 circuit breaker?
The Crabtree Circuit breaker B40 is an automatically operated electrical switch. It will protect an electrical circuit from damage caused by excess current from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected.
How do I know what kind of breaker box I have?
Circuit breakers have markings stamped on the side of them and are usually located inside the panel cover door. There is a label that will tell you what type of breaker is needed for installation in that particular panel.
What is an AK breaker?
AK/AKR Circuit Breaker Parts Circuit breakers protect equipment from damage due to current overload or short circuit by interrupting the current flow if a fault is detected. AK and AKR low voltage circuit breakers from GE are designed for heavy-duty use in commercial, industrial and utility applications.
What does 2 pole and 4 pole mean?
2 pole motor has two poles (or a single pair of magnetic poles) while 4 pole motors have four magnetic poles in alternating order. 2 pole motors have twice the speed of a 4 pole motor.
What is the difference between 3 pole and 4 pole MCCB?
TP MCB is used in 3phase 4wire system. It is denoted as TP+N which will mean a three pole device with external neutral link which can be isolated if required. For the 4 pole breakers, protection applies to current flow through all poles. However when breaker trips or manually opened, all poles are disconnected.
What amp do I need for an electric shower?
40 amps
Electric Shower Power Ratings and Power Cable Information Fuses and switches should be rated at 32 amps. Showers up to 9kw may carry a 6mm cable as long as the shower unit is within 18 meters of the fuseboard. Fuses and switches should be rated at 40 amps.
What is the difference between a 3-way and a 4-way switch?
A three-way switch has three terminals; a four-way has four. These control a light from two or three switch locations, such as at the top and bottom of a stairwell, at either end of a hallway, or in a large room with multiple entrances.
What rating is the measure of the ability of a fuse or circuit breaker to safely open an electrical circuit under fault conditions?
The interrupting-capacity (IC) rating of an overcurrent device is the maximum fault current that the device can interrupt without damage to itself. Most circuit breakers and fuses have an IC rating of 10,000 amps.
