Expected electrical life (resistive load)
|Form A contact||Standard type||Long life type|
|35 A 277 V AC||3×10⁴||5×10⁴|
|30 A 220 V AC||—||10⁵|
|20 A 277 V AC||10⁵||2×10⁵|
Reduced coil holding voltage* contributes to saving
energy of equipment
The coil holding voltage can be reduced up to 30% V of the rated coil voltage.
This equals to operating power of approximately 170 mW, which contributes equipment energy savings.
* Coil holding voltage is the coil voltage after 100 ms from the applied rated coil voltage.
Contact gap: 3.2 mm
Compliant with European photovoltaic standard VDE0126 Compliant with EN61810-1 2.5 kV surge withstand voltage (between contacts)
Contact gap (initial)
|Form A contact||Min. 3.2 mm each contact|
|Form B contact||Min. 0.7 mm
Min. 0.5 mm (When Form A contact welded)
Detection of main contact welding makes it possible to construct a safety circuit.
・Designed so that Form A contact and Form B contact will not close at the same time.
・When Form A contact welded, Form B contact gap of at least 0.5 mm is maintained.
|Note||:||Form B contact, when used to monitor the condition of Form A contact, can beused exclusively as an auxiliary contact.|
|Conditions||Normal operation||When Form A
|Between Form A contact and coil||Min.11.0 mm (Clearance/Creepage)|
|Between Form B contact and coil||Min. 3.2 mm (Clearance/Creepage)|
|Between Form A contact sets||Min. 8.2 mm (Clearance/Creepage)|
|Between Form A contact and Form B contact||Min.12.8 mm (Clearance/Creepage)|
