Thermal Relays

RSM Thermal Relays in the event of overload or failure of one phase of disabling motor via contactor, provide protection to the engine.

Thermal role in accordance with the standards EN 60947-4- 1 up to 95 from 9 in a variety of rated current 3 kA short circuit breaking capacity and ISO 9001: 2000 management system are produced in accordance with CE and RoHS certified. Thermal Relays have been compensated against ambient temperature and sensitive to phase loss are produced. compensated thermal relay and the ambient temperature, without affecting more than at ambient temperature (thermal overload relay specified in the standard) limitations on the work.

If one breaks the conductive phase and 2-phase motors remains as soon pulling more current than normal. It allows you to online on the phase-sensitive thermal overload relay in the event of loss of one phase of withdrawal from normal more quickly to protect the increasingly ac motors.
