Informasi Produk
Fitur Utama & Penggunaan Tipikal
Konfigurasi Kutub Fleksibel
Satu keluarga produk mencakup empat tipe sirkuit: 1P dan 2P untuk sirkuit AC230V satu fasa, 3P dan 4P untuk sirkuit AC400V tiga fasa dengan atau tanpa saklar netral. Karena kutub dan rating arus berbagi format modular yang sama, panel dapat dirancang sekali dan disesuaikan untuk setiap sirkuit tanpa mengubah tata letak.
Desain Kompak, Ramah Panel
Kecil dan ringan, kontaktor menempati ruang modular yang sama dengan perangkat proteksi di sekitarnya — ideal untuk kabinet kontrol kompak, papan sub-distribusi, dan pekerjaan retrofit di mana tidak ada ruang untuk kotak saklar terpisah.
Pemasangan Rel DIN Cepat
Badan klip cepat dipasang pada rel DIN standar TH35-7.5, mengurangi waktu pemasangan dibandingkan dengan switchgear yang dipasang dengan sekrup dan menjaga konsistensi pengkabelan dengan bagian lain papan. Terminal menerima kabel fleksibel 2×2,5mm² atau kabel kaku 6mm² pada frame 16-25, dan kabel fleksibel 2×10mm² atau kabel kaku 25mm² pada frame 40-63.
Umur Pakai Panjang
Umur mekanik minimal 1.000.000 operasi dan umur listrik minimal 100.000 operasi secara signifikan mengurangi frekuensi perawatan dan biaya jangka panjang pada instalasi di mana kontaktor dioperasikan oleh jadwal atau sensor berkali-kali setiap hari.

EXCH7 — Switching Koil untuk Pencahayaan, Pemanasan, dan Layanan Bangunan
Otomasi mencapai papan distribusi melalui koil. Timer, sensor cahaya siang, termostat, output PLC, atau sistem manajemen bangunan hanya menyediakan sinyal kontrol; sesuatu harus mengalihkan beban aktual, dan harus dilakukan di dalam enclosure yang sama dengan perangkat proteksi. Kontaktor modular EXCH7 dirancang untuk posisi tersebut: saklar yang dioperasikan koil dalam housing rel DIN, tersedia dari 1 hingga 4 kutub dan 16A hingga 63A, sehingga grup pencahayaan, sirkuit pemanas, instalasi ventilasi, dan pasokan peralatan dapat dikontrol dari papan distribusi daripada dari panel terpisah.
The series is rated AC 230V for single-phase versions and AC 400V for three-phase versions, with a 500V insulation class and utilisation categories AC-7a and AC-7b covering slightly inductive loads and the motor loads of household appliances respectively. Contact combinations range from a single normally open group on 1P models to the 4P combinations 40, 04, 22 and 31 — enough flexibility to match indicator, interlock and changeover schemes without adding auxiliary relays. Coil voltages of 24V, 48V, 110V and 230V cover the usual control supplies, and the coil closes reliably anywhere between 85% and 110% of rated voltage.
HUYU manufactures the EXCH7 modular contactor at our own factory and supplies industrial automation, building facility and appliance-control customers, panel builders, wholesalers and distributors at factory-direct prices, with coil variants, OEM marking and complete IEC 61095 test documentation.

Kami Memproduksi, Anda Memberi Merek
The EXCH7 is produced on our own modular contactor lines: coil winding and impregnation, contact bridge riveting and mechanism assembly are all carried out in-house, and the finished unit is calibrated before the housing is closed. Batch samples are tested for pick-up and drop-out voltage, contact resistance and temperature rise at rated current, and mechanical cycling is checked against the rated life.
For OEM customers we produce coil voltage variants, contact combinations and marking to match an existing control-panel programme, and pack to the customer’s own carton specification.
- Pemberian merek OEM — device marking, rating labels and packaging for panel, HVAC and appliance brands.
- Opsi ODM — coil voltages, pole and contact combinations, terminal arrangements to your specification.
- Quality documentation — IEC 61095 and GB/T 17885 test records with each production batch.
- MOQ — flexible wholesale quantities; mixed poles, ratings and coil voltages in one order.
Panduan Pembelian
Selecting an EXCH7 comes down to four decisions: how many poles the circuit needs, what current it switches, which utilisation category applies, and what control voltage the coil should accept.
- Decide the poles: 1P or 2P for AC230V single-phase circuits, 3P or 4P for AC400V three-phase circuits with or without switched neutral.
- Match the current to the load — 16A, 20A, 25A, 40A or 63A according to the pole configuration chosen.
- Confirm the utilisation category: AC-7a for lighting, heating and similar slightly inductive loads; AC-7b where appliance motor loads are involved, using the corresponding control power rating.
- Select the contact combination (10 / 20 / 02 / 11 / 30 / 40 / 04 / 22 / 31) to suit the control scheme.
- Choose the coil voltage from 24V, 48V, 110V or 230V AC to match the controller, timer or BMS output.
- Provide upstream protection sized for the circuit; the contactor switches the load but does not clear faults.
- Request samples and confirm OEM marking or coil specification before mass production.

Pertanyaan yang Sering Diajukan
What is a modular contactor and how does it differ from a circuit breaker?
A modular contactor is a coil-operated switch in the same modular housing format as a miniature circuit breaker, so it clips onto a DIN rail inside a distribution board. The difference is function: a circuit breaker protects the cable and equipment against overload and short circuit, while a contactor switches the load on and off in response to a control signal. In practice they work together — the breaker protects, the contactor controls.
What is the difference between AC-7a and AC-7b utilisation categories?
IEC 61095 defines AC-7a for slightly inductive loads — lighting, resistive heating and similar household and commercial applications — and AC-7b for the motor loads of household appliances. The category determines which control power and current rating apply: for the same 25A pole configuration, for example, AC-7a covers 5kW on 1P/2P while AC-7b covers 1.2kW. Always size the contactor against the category of the actual load.
How do I choose between the 1P, 2P, 3P and 4P versions?
1P switches a single line and suits basic AC230V control; 2P switches line and neutral together for full isolation of single-phase circuits; 3P switches three phases for AC400V loads; and 4P adds the neutral, which is required where three-phase circuits must be isolated completely. Available currents differ by pole count — 1P up to 25A, 2P from 16A to 63A, and 3P/4P from 25A to 63A.
Which coil voltage should I specify?
Match the coil to the control supply you already have: 24V or 48V for control systems and safety extra-low voltage circuits, 110V where an isolating transformer is used, and 230V for direct connection to a phase and neutral control circuit. All four are standard, and other specifications can be produced for OEM orders. The coil will close reliably at any voltage between 85% and 110% of its rated value.
What contact combinations are available?
The factory contact combinations follow the pole configuration: 10 for 1P; 20, 02 and 11 for 2P; 30 for 3P; and 40, 04, 22 or 31 for 4P models. These combinations of normally open and normally closed groups allow indicator circuits, interlocking or multiple load groups to be handled without adding separate auxiliary contactors.
Where is the EXCH7 typically used?
The series is intended for industrial automation, building facilities and home appliance control, where high reliability and flexible configuration matter. Typical duties include switching lighting groups by time clock or sensor, controlling heating and ventilation plant from a BMS, and switching appliance or socket circuits where a low-power control signal has to operate a larger load.
