Components of miniature circuit breaker strip gauge
A miniature circuit breaker (MCB) strip gauge is a crucial component in an electrical panel that helps to identify the correct MCB to be installed in a specific circuit. Here are the components of a typical MCB strip gauge:
- Strip: The strip is the main component of the MCB strip gauge. It is a thin, flat piece of metal with a series of notches or slots of varying widths.
- Notches or Slots: The notches or slots on the strip are designed to match the corresponding MCB sizes. Each notch or slot represents a specific MCB size, such as 1A, 2A, 3A, etc.
- Index Mark: The index mark is a small notch or line on the strip that indicates the starting point of the notches or slots. This helps to ensure that the correct MCB is installed in the correct position.
- Label: The label on the strip gauge typically indicates the MCB sizes corresponding to each notch or slot. This helps to quickly identify the correct MCB size.
- Mounting: The strip gauge is usually mounted on a backing plate or a panel, which provides a secure and rigid base for the strip gauge.
- Clips or Retention Mechanism: Some MCB strip gauges may have clips or a retention mechanism to hold the MCB in place once it is inserted into the correct notch or slot.
The components of an MCB strip gauge work together to provide a simple and efficient way to identify and install the correct MCB in an electrical panel.
