The terminals of the 3RP1 time relays are designed for connections of the
control cables with a maximum stripped length of 10 mm. Cross-sections of
2
2 x 0.5 to 2.5 mm (single-coil) and 2 x 0.5 to 1.5 mm
clamped with a wire end ferrule.
Screw-type terminal (SIGUT
The 3RP10 and 3RP15 time relays are available with plus-minus Pozidriv 2
screw-type connections.
Cage Clamp terminal
The 3RP10 and 3RP15 time relays are available with Cage Clamp terminals.
There are no restrictions on the control supply voltage, switching current, or
duty cycle for operation between -25 °C to +60 °C.
There are up to 15 time settings, ranging from 0.05 s to 100 hr. The 3RP15
has additional time settings between the decade scales (1/10/100 s/min/h)
that make high setting accuracy possible.
There are multifunctional relays with a wide voltage range of 24 VAC/VDC to
240 VAC/VDC.
The electrical service life with contactor load (e.g. 3RT1016 contactor) is 10
million operating cycles.
The electrical service life at AC voltage of 230 V, utilization category AC-15/
3 A, and at DC voltage, utilization category DC-13/1 A, is 100,000 operating
cycles.
In the case of functions that require a continuous auxiliary supply to termi-
nals A1/A2 and A3/A2, the time function can be started by a control supply
voltage to terminal B1 or B3.
The following specifications must be complied with to ensure error-free
operation of the solid-state time relays:
Only apply the control supply voltage from start input B1 or B3 once the
supply voltage has already been applied to A1/A2 or A3/A2.
Identical potential must be applied to terminals A1 and B1 or A3 and B3.
