Three phase Polarized latching relay TP41-12, with continuous switching current capability up to 80A. The relay coil can be designed to single winding and double winding with coil voltage from 5VDC to 48VDC. The advantage of polarized latching relays is the pulse driven operation of some milliseconds, coil heating can be neglected. The relay is designed and manufactured in accordance to IEC 61810-1 .
1. Three phase 80A switching capability;
2. Both Single coil and double coil can be customized, the coil rated voltage can be 5VDC-48VDC;
3. Multi-layer blades, low temperature rise;
4. Silver alloy contacts materials AgSnO2, with reliable electrical endurance;
5. Outline dimension:100mm×45mm×21mm;
6. Environmental protection (comply with ROSH) ;
7. Cost Efficiency.
