Bistable Design: The contact state is switched by pulse signal (duration 50ms~1s). No continuous power supply is needed after switching, featuring ultra-low power consumption (different from the continuous power supply of ordinary relays).
High Compatibility: Complete AC/DC coil voltage specifications, suitable for different control circuits.
Miniaturization: حجم صغير, suitable for dense control cabinet layout.
التطبيقات النموذجية
Suitable for low-power on-off control scenarios, مثل:
– Energy-saving control of lighting circuits
– Switching of small loads (على سبيل المثال, solenoid valves, indicator lights)
– Signal-triggered on-off circuits in automation equipment

Key Selection Instructions (Essential for Sales/Quotation Scenarios)
- Core Selection Dimensions:
– عدد البولنديين (1P~4P): Select according to the number of control circuits (على سبيل المثال, 1P for single-circuit lighting, 3P for three-phase equipment);
– التصنيف الحالي (10A/16A/20A/25A): Load current ≤ 80% of rated current (على سبيل المثال, it is recommended that the load of 16A model ≤ 12.8A);
– الجهد لفائف: Must match the customer’s control circuit voltage (AC 220V and DC 24V are the most commonly used specifications, which can be recommended first in quotation).
- Load Compatibility:
– Suitable for resistive loads (lighting, أفران المقاومة) and low-power inductive loads (small solenoid valves, fans). For capacitive loads, derating by 50% مطلوب.
- Quotation and Supply Tips:
– Regular coil voltages (تيار متردد 220 فولت, DC24V) are in sufficient stock, while special voltages (على سبيل المثال, AC12V, DC6V) need to be stocked 3~5 days in advance;
– Tiered prices are available for bulk purchases (≥ 100 وحدات). Neutral packaging or CHINT original packaging is supported for export orders (to be specified in advance).
