EATON CLD Series Electronic Molded Case Circuit Breakers, L Frame


Eaton CLD Series moulded case circuit breakers are used in various electrical systems for monitoring and control applications. They feature an electronic trip unit to monitor current flow and protect the critical electrical systems from damage due to short-circuit and overload conditions. They have an L-frame design that provides mechanical support for the breaker's internal components and terminals. The CLD Series also circuit breakers provide real-time... monitoring and data logging capabilities, allowing easy tracking of electrical usage and identifying potential issues in the system.Read more

Working Mechanism

  • These circuit breakers come equipped with an electronic trip unit that uses microprocessors to monitor the current flowing through conductors.
  • The trip unit measures the current flowing through the breaker's internal components and compares it with the set current rating of the breaker.
  • When an overcurrent condition is detected, the electronic trip sends a signal to open the main contacts and interrupt the current flow.
  • As the breaker trips, the indication LED on the front of the breaker illuminates and the trip records the event in its memory.

Frequently Asked Questions

What are moulded case circuit breakers?

The moulded case design of these circuit breakers provides mechanical protection for the internal components and easy installation in a panel or switchboard. They also withstand electrical and mechanical stresses during normal operation.

What is an arc fault?

The high power discharge of electricity between two or more conductors is defined as an arc fault. This electrical discharge dissipates heat, breaking down the wire's insulation and triggering a fire. Electronic breakers use advanced sensing and analysis techniques to detect unusual current patterns that may indicate an arc fault.

How to install an Eaton CLD Series moulded case circuit breaker in a panelboard?

  • Before installation, turn off the power to the electrical panel or switchboard.
  • Remove the appropriate breaker slot in the panel and install any necessary hardware like bus bars.
  • Connect the breaker's incoming and outgoing terminals to the bus bars in the panel.
  • Secure the breaker in the panel, ensuring proper alignment and tightening to the panel.
  • After installation, turn the power back on and test the breaker to ensure it operates smoothly.
