AR-Series
Railway hydraulic magnetic circuit breaker

Application

Under normal operating conditions, accidents may not appear to be a problem. However, normal operating conditions are not always guaranteed. Under strained or heavy use, a motor and/or another load-generating component within the equipment will draw additional current from the power source; when this happens, the equipment’s wires and/or components will overheat and may ultimately burn up.
 
In addition to protecting the equipment, the entire electrical system including the control switches, wires, and power source must be protected from faults. A circuit protection device should be employed at any point where a conductor size changes. Many electronic circuits and components like transformers have a lower overload withstand threshold level than conductors such as wires and cables. These components require circuit protection devices featuring very fast overload sensing and opening capabilities.
 

Description

Designed for those applications requiring higher amperage and voltage handling capability in a compact design. The AR-series compact circuit breaker has an unique arc shute design which results in high interrupting capacities. For increased mechanical strength and to achieve highest level/ rating on fire and smoke tests, a thermoset glass filled polyester halfshell
construction is applied.
 

Features

  • Compact design.
  • Unique arc shute method which results in higher interrupting capacities.
  • Thermoset glass filles polyester halfshell construction for increased mechanical strength, electrical strength and to achieve highest level/rating on fire and smoke tests.
  • Standard blue housing and white handle to improve visibility.
  • Up to 6 poles configurations.
  • 0.1 -50 amps up to 277 Vac or 80Vdc
  • Precise, temperature independent, operation.
  • Wide choice of time delays, terminal options and actuator colors.
  • The breakers can also be equipped with an optional mid-trip handle style actuator.
