Tipo de relevo térmico PTC MS220KA

PTC-relay for the monitoring of dry transformers. Alarm 1 with relay in closedcircuit current mode for preliminary warning, releases at over-temperature at PTC-set 1 and serves at the same time as functional monitoring. Alarm 2 in operating current mode. Thus no wiping signal occurs when switching on the supply voltage on. Additional terminals enable comfortable wiring from supply voltage to relays K1 and/or K2.

Changes from T221715/T221716 to T221717/T221718 (cURus, monitoring of sensors activatable, improved test function)
  • 2 PTC resistor sets
  • 2 output relays 1 change-over contact (co)/ 1 normally open contact (no)
  • monitoring of sensors for short-circuit and break activatable
  • TEST-button (delayed)
  • LEDs for ON, alarm 1 and 2
  • red LEDs for alarm 1 and alarm 2
  • K-type housing
  • Housing for mounting on DIN-rail 35 mm or wall-mount with screws M4
  • alternative to foreign product type TS-01

Part number:
T221718 AC 220-240 V
T221717 AC / DC 24-240 V
