Slim 20A Relay for HVAC and Major Appliances
Fujitsu Components has added a slim, 20A power relay to its product range that is targeted primarily at manufacturers developing commercial and industrial products.
The FTR-K3 is a 1Make (1 Form A) relay that has a nominal operating power of 780mW said to be the lowest power consumption in this class. Rated for a maximum load of 20A at 250VAC it is suited for switching compressor and inverter loads in air conditioners, refrigerators and other major appliances, as well as for use in office equipment.
The FTR-K3 has an operating temperature range of -40 to +60 degrees C. Dimensions of the slim-type relay are 30.1mm (L) x 15.7mm (W) x 23.3mm (H).
It features an 8mm clearance distance and a minimum 9.5mm creepage distance between coil and contacts for high-insulation resistance. It also has a surge withstand voltage of 8500V (min.), 1.2x50uSec and features a 1000V dielectric strength between contacts and 5000V dielectric strength between coil to contact.
The relay’s expected mechanical life is rated at 2 million operations. It has an electrical life of 100,000 operations at rated load (20A, 250VAC, Cos Phi 1).
The FTR-K3 meets UL, CSA, VDE and CQC agency approvals and uses UL94 flame class V-0 and UL CTI level class 2 plastics. It is constructed of lead-free materials and cadmium-free contacts to meet international environmental requirements.
The FTR-K3 series is available with TAB and PCB terminals in 5, 6, 9, 12, 18, 24, 48Vdc coil voltages.
