CB185-70 is a type of circuit breaker used in residential and commercial applications. It is designed to shut off power to a circuit or appliance when an over-current situation is detected. When an over-current situation is detected, such as from an overload or short circuit, the circuit breaker will trip, or switch off, thus protecting the circuit and its components from being damaged or destroyed.

CB185-70 is a two-pole, thermal-magnetic, molded-case circuit breaker. It is rated for a current of up to 70 amps. As its name implies, the CB185-70 operates with two distinct working principles.

First, the thermal part of the circuit breaker acts when current reaches a level that causes the temperature of the circuit breaker to rise above a certain point. The rise in temperature causes a bimetallic strip to bend, eventually shutting off the current flow. In contrast to the thermal part, the magnetic part of the device works by measuring the electromagnetism generated by a current overload. As the current increases through the circuit breaker, the magnetic field becomes stronger, activating a trip alarm.

CB185-70 circuit breakers are used in many types of installations where over-current protection is necessary. These include residential and commercial lighting fixtures, hot tubs, stoves, ovens, air conditioners, emergency lighting systems, irrigation systems, and pumps/boilers. The circuit breaker is also used in machinery such as milking equipment, saws, and other types of process equipment.

In addition to over-current protection, CB185-70 circuit breakers also provide arc-fault protection. Arc-fault protection is important for safety, as it helps prevent sparks, which can start fires, from occurring when two conductors come into contact. The circuit breaker is also capable of withstanding short-circuit current up to 7,500 amps.

CB185-70 circuit breakers are designed to be as user-friendly as possible, so that they can be easily installed and maintained. They feature a visible and audible trip indicator, so it is easy to tell when the breaker has tripped. Additionally, the CB185-70 offers diagnostic capabilities, so that potential problems with the circuit can be quickly determined.

In summary, CB185-70 circuit breakers are a reliable and cost-effective solution for a variety of residential and commercial applications. They are designed to provide both over-current and arc-fault protection, as well as diagnostic capabilities for troubleshooting. They are also easy to install and maintain, making them an ideal choice for many different types of installations.
