Contact amyu hpe lata ai gaw, laksan jai lang ai lam hpe madung tawn nna, circuit hpe hkang ai effect hpe hkra machyi shangun ai.
► N bung ai lit ni hpe .
Relay ni hta n bung ai load ni a matu laksan hparan ladat ni nga ra ai, dai hku nna matut mahkai hkra machyi ai lam n byin hkra. Load amyu myu gaw contact ni hpe n bung ai hku hkra machyi shangun na re. Ga shadawn, pyengdin n-gun ni gaw inrush current hpe shabyin ya na re; motor load ni gaw EMF hpe bai shapraw ya na re; inductive loads ni gaw electromagnetic induction surges ni hpe shabyin ya na re, etc. Tatut jai lang ai lam ni hta, load amyu hpan a arawn alai ni hpe laksan myit maju jung ra ai, dai hte maren, matut mahkai ai lam ni hpe makawp maga na matu, dai hte maren ladat ni hpe hkan sa ra ai.
► Matut mahkai na arung arai hte makawp maga lam
Contact material ni hta n-gun n law ai hte n-gun n rawng ai zawn re ai atsam ningja ni nga ra ai. Relay matut mahkai ai arung arai ni hpe lata ai shaloi, matut mahkai ai atsam hpe n-gun n law ai hte ngang grin hkra galaw ra ai, shanhte hta kaja ai n-gun n-gun hte anti-adhesion atsam ni nga ai hpe sadi ra ai.
Aten hte grup yin masa hpe lata la ai lam
► Ahkyak ai aten masat masa ni
Relay ni hpe lata ai shaloi, bungli galaw ai aten zawn re ai aten masat masa ni gaw mawdaw relay ni hpe nau n hkra ai, raitim, hpawng de ai relay ni a matu gaw, flashing frequency hpe myit yu ra ai. Mawdaw relay ni a matu bungli galaw ai aten gaw madung myit tsang ai lam n re ai sha, flashing frequency hte delay aten gaw combination relay ni a matu madung myit yu ra ai lam ni tai wa ai.
► grup yin masa hpe hparan ai lam
Relay ni gaw nbung katsi ai hte katsi ai shara ni hpe hkam sharang lu ai majaw, pat da ai hkrang shapraw ra ai. Relay ni hpe lata ai shaloi, shanhte hkrum katut na grup yin masa amyu myu, nbung katsi ai, nbung katsi ai, nbung katsi ai zawn re ai masa ni hpe atsawm sha myit yu ra ai. Grau nna, nbung katsi ai hte hka lim ai shara ni hta, relay aging hpe lawan ladan byin shangun chye ai; sealed design hpe lata ai gaw shi a bungli galaw ai lam hpe atsawm sha makawp maga ya lu ai.
