What Is a Contactor Relay Used For?
A contactor relay works like a small contactor but switches the low-power side of an installation: signalling, interlocking and the control lines that operate larger contactors, rather than the main load itself. A set of NO and NC contacts lets one relay close some control paths while opening others when its coil is energised.
Frequently Asked Questions
Does the coil polarity matter?
Yes. The polarity on the coil terminals, A1+ and A2−, must be respected.
Can a PLC switch the relay directly?
Yes. The low-consumption DC coil is suitable for direct control by PLC outputs.
How is this relay different from the JLab contactor?
The contactor (model LH 202/4-1) switches electrical loads and has overload protection; this relay is a DC-operated contactor relay for the control side of an installation.
What should an export enquiry include?
The quantity, the destination country and port or city, and your preferred delivery terms, for example FOB or CIF.
Who supplies this relay?
JLab (Jain Laboratory Instruments Pvt Ltd) of Ambala, Haryana, India.
