Control & Circuit Load Protection


Miniature Circuit Breakers are designed to protect equipment, systems and cables by a quick disconnection in case of short circuit or thermal overload.

  • Energy limiting design offers better protection than conventional breakers
  • Superior shock and vibration resistance capabilities
  • Finger-safe design

Miniature Circuit Breakers
[The Allen-Bradley 1492-SP is an energy limiting Supplementary Protector/Miniature Circuit Breaker.
In case of short circuit or thermal overload, these devices are designed to protect equipment, systems and cables by a quick disconnection.
They meet the requirements of UL 1077/CSA 22.2 No. 235 and are in conformity with IEC/EN 60 898.
When following appropriate standards, these devices protect energy loads such as controller I/O, solenoids, power supplies and control transformers from damaging power surges.
Residual Circuit DeviceResidual Circuit Device
The Allen-Bradley 1492-RCD is a line of devices to be used in association with Miniature Circuit Breakers 1492-SP. These devices are designed according to IEC/EN 61008 and approved by VDE.
Industrial applications often require earth leakage detection in addition to overload and short circuit protection. The 1492-RCD Residual Current Devices can detect earth leakage current and open the connected circuit to protect people and equipment.
