Miniaturization: Taille compacte, suitable for dense control cabinet layout.
Applications typiques
Suitable for low-power on-off control scenarios, tel que:

Key Selection Instructions (Essential for Sales/Quotation Scenarios)
- Core Selection Dimensions:
– Number of Poles (1P~4P): Select according to the number of control circuits (par ex., 1P for single-circuit lighting, 3P for three-phase equipment);
– Courant nominal (10A/16A/20A/25A): Load current ≤ 80% of rated current (par ex., it is recommended that the load of 16A model ≤ 12.8A);
– Tension de bobine: 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 (éclairage, fours à résistance) and low-power inductive loads (small solenoid valves, les fans). For capacitive loads, déclassement par 50% est requis.
- Quotation and Supply Tips:
– Regular coil voltages (AC220V, DC24V) are in sufficient stock, while special voltages (par ex., AC12V, DC6V) need to be stocked 3~5 days in advance;
– Tiered prices are available for bulk purchases (≥ 100 unités). Neutral packaging or CHINT original packaging is supported for export orders (to be specified in advance).
