70 Series
Type 70.61T - Monitoring relay 6A
Function and features:
Type 70.61T voltage monitoring relays for railway applications, 1 CO, for voltage monitoring of three-phase networks (208… 480) V:
– phase loss
– phase sequence
Features include:
- Compliant with EN 45545-2 + A1: 2016 standards (protection against fire and smoke), EN 61373 (resistance to shock and vibration, category 1,
class B), EN 50155 (temperature resistance and humidity, class T1) - Universal use (systems with UN from 208 V to 480 V, 50/60 Hz
- Detects phase failure error even in presence of regenerated voltage
- Positive safety logic (the relay contact output opens in case of error detection)
- 2 versions:
• 1 changeover, 6 A (17.5 mm wide)
• 2 changeover, 8 A (width 22.5 mm) - 35 mm rail (EN 60715) mounting
- European patent applied for, for the innovative principle underlying the monitoring system of the 3 phases and error detection
