EGEDC Series DC Circuit Breakers(22 Products)
EATON

• These circuit breakers are equipped with fixed thermal and fixed magnetic trip mechanisms to protect electrical systems against overload conditions:

Fixed Thermal Trips

• The thermal trip uses a bimetallic strip that is sensitive to changes in temperatures. When the current flow exceeds the rated value, the strip heats up and bends.
• This causes the contacts to open and interrupt the current flow.

Fixed Magnetic Trips

• The magnetic trip consists of an electromagnetic component that detects the presence of short circuits in a circuit. As the current rises, a magnetic field is generated that causes the displacement of the plunger in the tripping coil, forcing the contacts to open and interrupt the flow.

• These circuit breakers feature a fixed thermal & fixed magnetic trip that offers reliable overload and short-circuit protection, thus protecting wire and the equipment from damage.
• They also include a front-mounted handle that can be used to manually trip or reset the breaker.
• These circuit breakers have moulded cases to hold current-carrying components, trip devices and mechanisms integrated into one unit.
• Their three-pole design provides interrupting ratings of 35kA at 240VAC, 25kA at 480VAC and 18kA at 600Y / 347VAC, respectively.

Q. How is the tripping status indicated?

A. Eaton moulded case circuit breakers feature a trip flag to provide a visual indication of the TRIPPED and OFF status of the breaker.

Q. How to reset a moulded case circuit breaker that has been tripped?

A. A tripped breaker can be reset again by pressing the OFF and then the ON pushbutton, which closes the breaker contacts and retracts the current flow.
