circuit breakers

our extensive p&b circuit breaker product line includes thermal and magnetic types. termed secondary breakers by ul, they protect equipment rather than branch circuits in buildings. one- to four-pole models are available in current ratings from milliamps through 50 amps.

thermal circuit breakers
due to their relatively low cost, thermal breakers are applied more broadly than magnetic breakers. thermal applications include:

Potter Brumfield circuitbreakers distributed by Industrial Electronics

magnetic circuit breakers
applications that might require the precision of a magnetic breaker include:

medical/dental diagnostic equipment
automation robotics
welders
elevators

m9/w9 series standard size magnetic circuit breakers
(approx. 0.75 x 2.5 x 2.1d [19 x 63.5 x 53.3d] per pole)

m6/w6 series compact size magnetic circuit breakers
(approx. 0.75 x 2.0 x 1.64d [19 x 50.8 x 41.7d] per pole)

line conditioning
treadmills
hvac (transformer)
appliance (range hood)
cable tv converters
spa controls
uninterruptible power supplies
rvs (hvac system)
appliance (range)
test and measurement
pool heaters
bowling pin spotters
copy machines
vending machines
general aviation aircraft
medical equipment

circuit breakers

p&b circuit breakers include both thermal and magnetic types in ratings from milliamps to 50 amps. the information below may help users to quickly differentiate these two types of p&b circuit protectors:

thermal circuit breakers

typically less expensive.
trip point varies with the ambient temperature.
one- and two-pole models only.

magnetic circuit breakers

typically more expensive.
temperature stable over a wide range.
available with different time delays before tripping.
one- through four-pole models.

our e-catalog comes complete with a step-search function that will help you to select an appropriate circuit breaker for your application.
