1SVR760489R8300

1SVR760489R8300 is a multifunctional relay from the CM three-phase monitors range. It operates with a rated control supply voltage / three-phase measuring voltage of 530-820VAC 50/60Hz and has a 2 c/o (SPDT) output with contacts rated at 250V / 4A. This relay monitors all phase parameters such as over/undervoltage, phase unbalance and phase failure. The corresponding threshold values are adjustable. It also offers selection of phase sequence monitoring, automatic phase sequence correction as well as an ON or OFF tripping delay. The output contacts can be configured as 1x2 c/o (SPDT) contacts (common signal) or 2x1 c/o (SPDT) contact operation. The tripping delay is adjustable over a range of instantaneous to 30s (0, 0.1-30s). The device offers maintenance free Easy Connect Technology with push-in terminals. It is IEC/EN 63000 IEC/EN 60255-27, IEC/EN 61000-6-2, IEC/EN 61000-6-3 approved.
