All switches have a breaking capacity. The number 60947-3 is not a switch number it is an IEC standards publication that relates to panel mounted switches. The publication sets out specifications that manufacturers have to adhere to so as to get their equipment approved for use.
No. A T2AH fuse is a high-breaking capacity type whereas a T2L is low-breaking capacity. Often, High-breaking capacity fuses have ceramic (hence stronger) tubes and low-breaking capacity fuses have glass tubes. High-breaking capacity fuses are able to protect against higher short-circuit currents than low-breaking capacity ones (which could explode under the same conditions).
Depends on manufacturer..Normally the ratings are as follows 1. Service short circuit breaking capacity is 7.5 kA 2. Rated short circuit breaking capacity is 10 kA.
HRC stands for 'high rupture capacity'. An alternative abbreviation is 'HBC, meaning 'high breaking capacity. The rupture (or breaking) capacity is a term describing the maximum short-circuit current that the fuse can safely interrupt at its rated voltage. Most fuses will safely interrupt any level of fault current between a current that just causes the fuse to operate (melt), up to their maximum breaking capacity- such fuses are called 'full-range'. HRC fuses usually have strong, ceramic bodies to withstand the huge pressure generated when the fuse has to interrupt a large short-circuit current. In contrast, low breaking capacity fuses have weaker bodies made from materials such as glass.
switching on the tourch for example is when as you switch it on it will move the switch connecting it to a circuit that lights up the bulb and when you switch the switch off the switch will move breaking the circuit
for instance, breaking into a series run of cable to install a switch for a device.

High Breaking Capacity
Rupturing capacity:Rupturing capacity or breaking capacity expresses the current that a circuit breaker is capable of breaking at a given recovery voltage under certain set conditions of operation. It is expressed in MVA The set conditions are power factor,recovery voltage and rate of rise of restriking voltage. When the current broken is symmetrical it is called symmetrical breaking capacity. When the current broken is asymmetrical it is called asymmetrical breaking capacity. It is common to designate circuit breaker capacity based on asymmetrical breaking capacity. Breaking capacity of a circuit breaker =√3xVxIx10-6MVA Short circuit breaking capacity: It is the highest value of short circuit current which a circuit breaker is capable of breaking under specified conditions of transient recovery voltage and power frequency voltage. It is expressed in kA. The breaking current is expressed in two ways1)The r.m.s value of a.c component of current at the instant of contact separtation.2)The percentage of d.c component of current at the instant of contact separtation. While selecting the circuit breaker for a particular location in the power system the fault level at that point is determined.

Typically, glass fuses have a low breaking capacity, while ceramic ones have a high breaking capacity. This is to help protect the surrounding circuits from molten material. And maybe the technician.
