Ngwa mgbanwe

1. Fuse:
A na-eji ya eme ihe dị ka nchekwa mkpirisi okirikiri.Mgbe sekit ahụ dị mkpụmkpụ ma ọ bụ buru ibu nke ukwuu, ọ ga-adaba ozugbo wee bepụ sekit ahụ maka nchekwa.A na-ekewa ya na ụdị izugbe na ụdị pụrụ iche nke semiconductor.

2. Ibu ngbanwe / fuse mgba ọkụ (gbanwee fuse otu):
Ngwa igwe na-agbanwe igwe nwere ike jikọọ, iburu ma kwusi ike ugbu a na-ebu ugbu a n'okpuru ọnọdụ adịghị mma (mgbanwe ndị a enweghị ike ịpụpụ njikọ mkpirisi mkpirisi ugbu a na-adịghị mma)

3. Ihe mgbaji sekit (ACB):
Ogo nke ugbu a bụ 6300A;Akara voltaji ruo 1000V;Ike imebi ihe ruru 150ka;Mwepụta nchebe site na iji teknụzụ microprocessor.

4. Ihe mgbaji sekit (MCCB):
Ogo nke ugbu a bụ 3200A;Akara voltaji ruo 690V;Ike imebi ihe ruru 200kA;Ntọhapụ nchebe na-anabata teknụzụ ọkụ eletrik ma ọ bụ microprocessor.

5. Obere sekit breaker (MCB)
Ogo nke ugbu a abụghị ihe karịrị 125A;Akara voltaji ruo 690V;Ike imebi ihe ruru 50kA

6. Thermal electromagnetic ntọhapụ na-nakweere
Ihe mgbaji sekit (rccb/rcbo) RCBO bụ nke MCB na ngwa ndị fọdụrụ ugbu a nwere n'ozuzu ya.Naanị ihe mgbaji sekit nke nwere ihe nchekwa ihe fọdụrụ ugbu a ka a na-akpọ RCCB, ma ihe nchekwa ihe fọdụrụ ugbu a ka a na-akpọ RCD.
