B-LINE D4PR1R1 – Frequently Asked Questions
1) What coil voltage does the B-Line D4PR1R1 relay use?
The D4PR1R1 is a 12V coil relay. If your control circuit runs 24V or 120V, this is the wrong part number for it. B-Line notes that additional coil voltages are available in the D4 series, so specify the coil voltage that matches your control transformer or DC supply when ordering.
2) Is the D4 Series plug-in relay SPDT or DPDT?
Single pole double throw. The D4PR1R1 gives you one common with a normally open and a normally closed contact, so it will switch one load one way or the other, not two independent circuits. If you need two isolated switched circuits from one coil, a double pole relay is what you want instead.
3) How much current can the D4PR1R1 relay contacts actually switch?
Resistive loads: 10A at 250 Vac or 30 Vdc. Inductive loads (motors, solenoids, contactor coils) derate to 7.5A at 250 Vac and 5A at 30 Vdc. Maximum switching voltage is 380 Vac or 125 Vdc. Size the relay off the inductive figure any time you are pulling in a motor or a coil, not the 10A headline rating.
4) Can I use this 12V relay to switch a 120V lighting or receptacle circuit?
Yes, that is the normal use. The coil is 12V and the contacts are rated to 250 Vac, 10A resistive, so a 12V control signal can switch a 120V load up to 10 amps resistive. On ballasts, drivers, or motors use the inductive rating of 7.5A at 250 Vac instead.
5) Does the D4PR1R1 come with a socket or base, and does it need one?
It is a plug-in relay, so it mounts into a matching socket or base rather than wiring direct, and the relay ships as a single piece with no socket included. Order the socket separately, and add a DIN rail or panel mount base if your enclosure needs one.
6) Does this relay have an LED to show when the coil is energized?
The D4PR1R1 as configured has a plain cover and no indicator lamp. An indicator lamp version is offered in the D4 series, so if your techs rely on seeing pickup at the panel, specify that option instead of this part number.
7) What is the exact manufacturer part number for this B-Line general purpose relay?
D4PR1R1, from the B-Line D4 series: 12V coil, SPDT, 10A. That is the number to quote when matching spares to an existing panel.
8) Is a 10A plug-in relay enough for a fractional horsepower motor or a fan?
Check it against the inductive rating, not the 10A figure. Motors and fans are inductive, so the usable limit is 7.5A at 250 Vac or 5A at 30 Vdc. If the motor's full load amps sit near or above that, use the relay as a pilot device to drive a proper contactor rather than switching the motor directly.
