Product Description

Three phase Polarized latching relay TP41-10A, with continuous switching current capability up to 120A. 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 as well as meet the requirements of IEC 62055-31.

 

1. Three phase 120A 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. Conform to IEC 62055-31 UC3 Rating;

6. Outline dimension:116mm×52mm×28mm;

7. Environmental protection (comply with ROSH) ;

8. Cost Efficiency.
