RF8 features FRONT PROTECTION COVER OF THERMAL OVERLOAD RELAYS A sealable protection cover is available. When fitted on to the relay front, it precludes all possible adjuster tampering and involuntary activation of the Reset and Stop buttons of the thermal overload relay. CLEAR IDENTIFICATION OF THERMAL OVERLOAD RELAY MANUAL OR AUTOMATIC RESETTING The RF8 thermal overload relay is supplied configured for manual resetting. Breaking the plate below the Reset button allows for the automatic resetting configuration. FIXING EASE OF THE THERMAL OVERLOAD RELAY While the thermal overload relay is being linked to the contactor, its auxiliary contact fits on and connects to the coil terminal by rigid terminal. Complete relay fixing is done in a single operation, with no need of other connections. SEALABLE RELAY COVER A handy closing flap feature excludes any tampering of the thermal overload relay adjuster.

General characteristics The DRPT is a thermal protection relay for motors equipped with thermistor PTC sensors immersed in the winding heads. The maximum number of thermistors to be used is limited by the resistance of all the sensors connected in series; total ohmic value is not to exceed 1.5kΩ at 25 C. The DRPT type has fail-safe operation: the protective feature trips even in the case the PTC circuit is disconnected or there is a lack of voltage. Resetting is manual or automatic. Operational characteristics Supply circuit Rated frequency: 50-60Hz for AC types only Operational limits: Us Maximum dissipation: 2.5W Connection: permanent. Measuring circuit Type of connectable PTC sensor: According to DIN Total PTC resistance at 25 C: 1.5kΩ Tripping resistance: kΩ Resetting resistance: kΩ Voltage at PTC terminals: 2.5VDC. Remote resetting Control: NC contact opening Contact voltage: 5VDC Current consumption: about 1mA. Relay output Arrangement: 1 relay with 2 changeover contacts Rated operational voltage Ue: 250VAC Conventional free air thermal current Ith: 5A Designation to IEC/EN : B00 Mechanical life: 50x 6 cycles Electrical life (with rated load): 2x 5 cycles.
