Temperature and three-phase monitoring relay NAT10

Functionl description

The NAT10 is an electronic device designed to check the correct sequence and phase loss in a three-phase network and to control motor or electrical cabinet temperature via an external PTC.

Application fields

• Sequence and phase failure control in a three-phase network
• Temperature monitoring

Main features

• Three-phase supply voltage: 200VAC ÷ 500VAC (50 ÷ 60 Hz)
• Change over relay output for phase control:  250V, 3A
• Change over relay output for temperature control:  250V, 3A
• 3 Signaling LEDs: yellow for main power supply presence, green to indicate the correct sequence of phases, red for over temperature
