2. Bosch (company) - Wikipedia

   en.wikipedia.org/wiki/Bosch_(company)

   Robert Bosch GmbH (/ b ɒ ʃ /; German: ⓘ), commonly known as Bosch (styled BOSCH), is a German multinational engineering and technology company headquartered in Gerlingen, Baden-Württemberg, Germany. The company was founded by Robert Bosch in Stuttgart in 1886. [2] Bosch is 94% owned by the Robert Bosch Stiftung, a charitable institution. [3]

3. Automotive fuse - Wikipedia

   en.wikipedia.org/wiki/Automotive_fuse

   Bosch type fuses (also known as ceramic, porcelain, continental, torpedo, European, or GBC type fuses) are used in old (often European) automobiles. The physical dimension of this type of fuse is 6×25 mm with conical ends. Bosch type fuses usually use the same color-coding for the rated current. The DIN standard is 72581/1.

4. Contact breaker - Wikipedia

   en.wikipedia.org/wiki/Contact_breaker

   Breaker arm with contact points at the left. The pivot is on the right and the cam follower is in the middle of the breaker arm. A contact breaker (or "points") is a type of electrical switch, found in the ignition systems of spark-ignition internal combustion engines. The switch is automatically operated by a cam driven by the engine.

5. Jackhammer - Wikipedia

   The connection end size is also related to the breaking energy of the tool. For example, the Bosch and Hilti 12 lb (5.4 kg) tools both use SDS-max, while the Bosch, Hilti, and Makita 65 lb (29 kg) tools all use 1+1/8 in hex connection. See hammer drills for more on electropneumatic hammering.

6. Vacuum interrupter - Wikipedia

   en.wikipedia.org/wiki/Vacuum_interrupter

   After the 1970s, vacuum switches began to replace the minimal-oil switches in medium-voltage switchgear. In the early 1980s, SF6 switches and breakers were also gradually replaced by vacuum technology in medium-voltage application. As of 2018, a vacuum circuit breaker had reached 145 kV and the breaking current had reached 200 kA. [4]

7. Residual-current device - Wikipedia

   en.wikipedia.org/wiki/Residual-current_device

   A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device, more specifically a form of Earth-leakage circuit breaker, that interrupts an electrical circuit when the current passing through line and neutral conductors of a circuit is not equal (the term residual relating to the imbalance), therefore ...

8. Sulfur hexafluoride circuit breaker - Wikipedia

   en.wikipedia.org/wiki/Sulfur_hexafluoride...

   Sulfur hexafluoride circuit breakers protect electrical power stations and distribution systems by interrupting electric currents, when tripped by a protective relay. Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride (SF 6 ) gas to cool and quench the arc on opening a circuit.

9. Stab-Lok - Wikipedia

   en.wikipedia.org/wiki/Stab-Lok

   According to ANGI Homeservices, formerly known as Angie's List, If your home has a Federal Pacific Electric (FPE) circuit breaker panel with Stab-Lok circuit breakers, you run a significant risk of breaker malfunction and fire. While these types of circuit breakers were once commonly installed in houses across the country, many are defective.
