PTC thermal relay type MSR220K6

The MSR220K6 monitors up to 6 PTC-resistors sets with up to 6 PTCs each at the same time. If a temperature rise occurs in one set, the output relay releases and LEDs show the overheated sensor. Switching-off is stored until a Reset. Thus enables to find the overheated sensor even when it has cooled down.

With the MSR220K6 only 4 mm space is needed per monitored PTC-circuit. It is especially suitable for monitoring drives with multiple motors, like cranes or robots. Instead of the PTC-sensors also contacts (normally closed) can be connected.
  • blocking rotors, heavy starts, countercurrent operation
  • undervoltage and phase failure
  • increased ambient temperature and hindered cooling

The MSR220K2 monitors 2 PTC resistor sets at the same time. If a temperature rise occurs in one set, the appropriate output relay releases. With this relay, 2 PTC-sets can be independently monitored.

T221958 AC / DC 24-240 V
