Working Mechanism

  • The rating plug is a small device that is inserted into the trip unit of the circuit breaker.
  • It contains a calibrated current-limiting fuse which limits the amount of current that flows through the circuit breaker.

Features

  • They are compatible with SK Series moulded case circuit breaker frames with MicroVersaTrip Plus & MicroVersaTrip PM type electronic trip units.
  • These plugs are available in current ratings ranging between 500 and 1200A, allowing for customisation and flexibility in circuit protection.
  • They are made of durable materials and can withstand harsh environmental conditions, like extreme temperatures and humidity.

Standards and Approvals

  • UL

Frequently Asked Questions

How to install the rating plug?

  • Before installing the rating plug, the circuit breaker must be turned OFF, and the trip unit must be removed.
  • The rating plug is then inserted into the trip unit and secured in place using screws or clips.
  • The circuit breaker is then reassembled and turned back on.

What happens if the rating plug's ampere rating is exceeded?

When an overcurrent occurs, such as a short circuit or an overload, the current flowing through the circuit breaker exceeds the rating plug's ampere rating. This causes the plug to melt, thus opening the circuit and stopping the flow of current.
