Why use a breaker instead of a fuse?
• Breakers add value to a design, providing convenience and
protection.
– A circuit breaker can be quickly and easily reset after it trips and the
circuit fault is corrected. If a fuse blows, a replacement fuse may not
be readily available.
– A breaker helps to maintain the proper protection value in the circuit.
After a fuse blows, the incorrect value fuse could be inserted.
– Some breakers can perform multiple functions
• Circuit protection
• Switching
• Indication

Secondary vs. Primary Circuit Breakers
(TE Relay Products makes secondary)
• Primary circuit breakers can stand alone and are rated to withstand
higher currents and short circuit values.
• Secondary circuit breakers must be backed-up by a branch circuit
breaker or approved fuse. They cannot be used without other
protection in series with the secondary breaker. Secondary circuit
breakers are sometimes referred to as supplementary protectors or
component protectors.

Thermal vs. Magnetic Breakers
What are the differences?
Thermal
Magnetic
• Temperature Sensitive
• Not Temperature Sensitive over
Operating Range
• Not Voltage Sensitive (same
unit can be used for AC or DC)
• Voltage Sensitive (different units
are typically used for AC vs. DC)
• Single and Double Pole
• Single or Multi-pole
• Fixed Trip Time Delay
• Various Trip Time Delays
• Push-to-Reset or Switch
Function
• Switch Function
• Limited Circuit Functions
• Variety of Circuit Functions
• Small Package Size
• Larger Package Size
• Lower Cost
• Higher Cost

How Thermal Breakers Work
Bimetal
Overcurrent through the specially formed bimetal causes it to heat up
and snap into a position that opens the contacts (one of the contacts is
attached to the bimetal). When the contacts open, an insulator slides
into position between the contacts to hold them open until the breaker
is manually reset.
page 6 / July 20, 2015
How Magnetic Breakers Work
Contacts
Armature/Trip Lever
Coil
Overcurrent through the coil generates
magnetic flux which attracts the armature and
trips the breaker, opening the contacts.
Manufacturer can extend time delay before
tripping by using higher viscosity fluid in the
breaker’s cylinder, slowing the piston.
