Pertanyaan yang Sering Diajukan

Apa fungsi dari Siemens Overload Relay 3RU21261FB0?

Siemens Overload Relay 3RU21261FB0 berfungsi sebagai proteksi termal untuk motor listrik 3 fasa. Relay ini melindungi motor dari kerusakan akibat beban lebih dengan menggunakan elemen bimetal terintegrasi yang mendeteksi kenaikan arus. Dilengkapi kontak bantu 1NO/1NC dan tegangan maksimum 690V AC, relay ini memutus aliran listrik saat arus melebihi batas aman.

Apa spesifikasi teknis Siemens Overload Relay 3RU21261FB0?

Spesifikasi teknis Siemens Overload Relay 3RU21261FB0 meliputi: frame size S0, 3 poles, kontak bantu 1NO/1NC, tegangan maksimum 690V AC, terminal sekrup, dan kompatibel dengan kontaktor seri SIRIUS frame size S0. Relay ini tidak memerlukan thermal unit tambahan karena sudah memiliki elemen bimetal terintegrasi dan tidak memiliki sensitivitas kehilangan fasa.

Di mana beli Siemens Overload Relay 3RU21261FB0 di Indonesia?

Anda dapat membeli Siemens Overload Relay 3RU21261FB0 melalui 3G Electric, distributor resmi yang memasok dan mengirimkan produk ini ke seluruh Indonesia. Kami menangani logistik dan bea cukai untuk memastikan produk sampai ke lokasi Anda. Hubungi kami untuk minta penawaran dan informasi ketersediaan produk.

Apakah Siemens Overload Relay 3RU21261FB0 kompatibel dengan kontaktor tertentu?

Ya, Siemens Overload Relay 3RU21261FB0 dirancang khusus untuk kompatibel dengan kontaktor seri SIRIUS frame size S0. Relay ini menggunakan terminal sekrup untuk koneksi yang mudah dan andal. Pastikan kontaktor yang Anda gunakan memiliki frame size S0 agar pemasangan sesuai dan proteksi termal berfungsi optimal.

Bagaimana cara memilih overload relay yang tepat untuk motor industri?

Untuk memilih overload relay yang tepat, perhatikan frame size yang sesuai dengan kontaktor, jumlah poles (3 poles untuk motor 3 fasa), tegangan maksimum (seperti 690V AC pada Siemens 3RU21261FB0), dan jenis kontak bantu (1NO/1NC). Pastikan relay memiliki elemen termal terintegrasi jika tidak ingin menambah thermal unit tambahan. Konsultasikan dengan teknisi untuk penyesuaian arus motor.
