Chiumbwa chenickel chemhangura, chine simba shoma rekudzivirira magetsi, hachipise kupisa uye hachiparadzi ngura, chiri nyore kugadzira uye chakasungirirwa ne lead. Chinoshandiswa kugadzira zvinhu zvakakosha mu thermal overload relay, thermal circuit breaker ine simba shoma, uye midziyo yemagetsi. Chinhu chakakoshawo pamagetsi ekupisa tambo. Chakafanana ne s type cupronickel. Nickel painoumbwa zvakanyanya, ndipo painochena sirivha yakawanda.
