Anything interfering with the strength of the compressive stress waves (7) during operation such as. blank-firing (free-running) or prying with the tool, can lower breaker performance and cause tool. fatigue. The breaker must be at a 90Â° angle to the face of the rock. (D)Blank-firing. Blank-firing the breaker without the tool pressing on a rock causes the energy that normally travels. out the tool into the rock (8), to impact the retainer pins (9) and front head causing excess stress to. these components.
âMCBâ stands for âMiniature Circuit Breakersâ while âMCCBâ is âMolded Case Circuit Breaker.â. The main difference between the two is their capacity with the MCB rated under 100 amps with an interrupting rating of under 18,000 amps.Consequently, their trip characteristics may not be adjusted since they basically cater to low circuits.ircuit breakers are usually reset after they have been âtripped.â Both MCB and MCCB are highly durable and could last for years depending on the manufacturer. When choosing between using an MCB and an MCCB, it is important to consider the amount of power that would be coursing through the device.
