Relay 733

Description

Polarized latching relay for 100 A

The relays are designed and manufactured in accord- ance to the Standards of IEC 61810, Part 1-00/VDE 0435, Part 201, which are also in accordance to the Low Voltage Directive (LVD).

The advantage of the polarized latching relays is the pulse driv en operation of 30 miliseconds. Therefore there is a low need of setting power and the coil heating can be neglected. Relay can be set by manual operation.

The relays are designed and manufactured in accordance to international standards of IEC 61810 part 1/VDE 0435 part 201 as well as they meet overload and short circuit requirements of IEC 62053/62054/62055(UC3).
