Alat pengendali instalasi listrik tenaga secara manual adalah ... .
- A.
  
  Kontaktor
- B.
  
  Saklar
- C.
  
  Konduktor
- D.
  
  Push Button
- E.
  
  Konvertor
Correct Answer
B. Saklar

Explanation
The correct answer is "Saklar". A saklar is a manual electrical switch that is used to control the power supply to an electrical installation. It allows the user to manually turn the power on or off. Unlike a kontaktor, which is an automatic switch, a saklar requires manual operation. Therefore, a saklar is the appropriate answer for a manual electrical control device.

- A.
  
  Manual control
- B.
  
  Magnetis control
- C.
  
  Perencanaan
- D.
  
  Semi otomatis control
- E.
  
  Manual magnetis control
Correct Answer
D. Semi otomatis control

Explanation
The given correct answer for this question is "semi otomatis control". This is because the question states that the power installation circuit operates using a magnetic contractor and push button. These components are commonly used in a semi-automatic control system, where the operator has some control over the operation of the circuit through the push button, but the magnetic contractor also plays a role in controlling the flow of electricity. Therefore, the correct answer is "semi otomatis control".

Suatu saklar yang bekerja berdasarkan kemagnetan lintrik adalah ....
- A.
  
  Push button
- B.
  
  Kontaktor magnet
- C.
  
  Limit switch
- D.
  
  Float switch
- E.
  
  TPDT
Correct Answer
B. Kontaktor magnet

Explanation
A switch that operates based on electromagnetic force is called a magnet contactor. It is used to control the flow of electricity in an electrical circuit by using a magnetic coil to open or close the contacts. This type of switch is commonly used in industrial applications to control large electrical loads.

Pengertian dari “interlocking” pada rangkaian instalasi motor listrik adalah ... .
- A.
  
  Dua motor yang bekerja bersama
- B.
  
  Dua motor bekerja berurutan
- C.
  
  Sebuah motor dikendalikan dari beberapa tempat
- D.
  
  Motor bekerja secara otomatis
- E.
  
  Dua motor bekerja bergantian
Correct Answer
E. Dua motor bekerja bergantian

Explanation
The term "interlocking" in the context of electrical motor installations refers to two motors working alternately or in sequence. This means that both motors take turns operating, rather than operating simultaneously or independently.

Cincin hubung singkat pada magnetik kontaktor berfungsi untuk ... .
- A.
  
  Agar kontaktor tidak bergetar
- B.
  
  Menahan kontak
- C.
  
  Menghasilkan arus searah
- D.
  
  Membalik ggl induksi
- E.
  
  Mengikat inti besi
Correct Answer
A. Agar kontaktor tidak bergetar

Explanation
The short-circuit ring on the magnetic contactor functions to prevent the contactor from vibrating. When an electrical current passes through the contactor, it creates a magnetic field that causes the contactor to vibrate. The short-circuit ring helps to stabilize the contactor and prevent this vibration, ensuring that the contactor remains in a stable position and operates effectively.

Kontaktor type SN 21, mempunyai ....
- A.
  
  1 HC, 3 NO, 1 NC
- B.
  
  2 HC, 4 NO, 2 NC
- C.
  
  2 HC, 5 NO, 1 NC
- D.
  
  1 HC, 5 NO, 1 NC
- E.
  
  1 HC, 5 NO, 2 NC
Correct Answer
E. 1 HC, 5 NO, 2 NC

Explanation
The correct answer is 1 HC, 5 NO, 2 NC. This means that the Kontaktor type SN 21 has 1 normally closed (NC) contact, 5 normally open (NO) contacts, and 2 holding coils (HC).
