Thermal protection relay for single-phase 1 ~ 230 V motor with a fan in, having a thermocontact tip end (marked TK, TW, TB, TP, PTO) outside the motor housing (box or fan connection cable).

Technical data

• switch with thermal protection
• fixed switch-off setting 10 A
• rated supply voltage 1 ~ 230 V
• motor rated current range 0.4-10.0 A
• IP20 protection (DIN rail mounting, model SET10E)
• degree of protection IP54 (surface mounting, model SET10)

To connect two thermocontact wires, make a bridge according to the diagram. After sufficient cooling of the motor windings, it is possible to switch it on again - if it happens too quickly, it will switch off after a maximum of 60 s. The power supply does not change the switching state.

Optional equipment is an auxiliary contact ZB (1NO- + 1NC) and blocking against unauthorized startup.
