What is the function of an LBB relay?
A local breaker backup relay is used to check the operation of distribution circuit breakers and to trip the feeder circuit breaker if the distribution circuit breaker fails to trip on an overload.
Can some body show me Electrical circuit diagram of Molded case circuit breakers?
Circuit breakers do not have circuit diagrams. The breakers have an input where the distribution voltage is applied and an output where the load is applied. If you want to know what is inside a breaker, the electrical terminology to use is "shop drawings" of the specific breaker that you need information on.
How is Circuit Breakers trip by Relays?
One common method (used for more than just differential relays) is to have a contact in series with one of the breaker trip coils, with this arrangement connected to a battery or AC power source. When the relay trips, the contact closes and current is allowed to flow through the trip coil, tripping the breaker. Some relays are self powered, and will use a capacitor to provide the current to the coil instead of a battery bank or AC power source. Differential relays often indirectly trip the associated breakers through a lockout relay. The differential relay trips the lockout, which has many contacts that close, tripping multiple breakers.
Can different rating circuit breakers have the same short circuit characteristics?
Yes, different amperage rating circuit breakers can have the same short circuit characteristics.
Will multiple tripping of a circuit breaker damage the circuit breaker?
You don't specify whether you mean low-voltage circuit breakers, such as MCBs (miniature circuit breakers) or high-voltage circuit breakers. In either case, repeated tripping under fault conditions causes arcing which damages the main contacts of the circuit breakers. For this reason, high-voltage circuit breakers are taken out of service after a specified number of tripping operations, so that the contacts can be maintained or, if necessary, replaced. MCB contacts are inaccessible, and the MCB may eventually require replacing.
Is there a relay switch or circuit breaker on a 94 sts?
There are multiple relays and circuit breakers in that vehicle.

Where can Square D circuit breakers be purchased?
Square D circuit breakers can be purchased from various homeware and DIY stores such as Home Depot or Lowes. Websites that specialise in circuit breakers such as Circuit Breaker Service or All Breakers do sell them as well.

Fuses are easier to use than circuit breakers?
For a home owner, yes they are.
Are circuit breakers are easier to use than fuses?
For a home owner, yes they are.
How do you reset a circuit breaker?
Most automotive circuit breakers reset themselves after they cool off. Some bigger trucks use circuit breakers that are reset manually. They have a button you push in to reset the breaker after it has cooled off.
