Product catalog summary

Specifications:
The document outlines the specifications for medium power industrial relays, specifically the 3R and 4R series. These relays are CSA certified and designed for compact high performance with direct panel mounting facilities. They are available in 1 Form C, 2 Form C, and 3 Form C contact arrangements, using silver alloy contact material. The rated voltage is 230VAC/24VDC, with a maximum voltage of 440VAC/220VDC and a maximum current of 10A. The relays have a nominal coil power of 1.1 Watts and an operating power of 0.7 Watts. They are designed to operate within an ambient temperature range of -40°C to +70°C and have a mechanical life expectancy of 10 million operations.

Coil Data:
The coil data includes nominal voltages ranging from 6V to 230V, with corresponding coil resistances and pick-up voltages for both AC and DC. For example, a 230V nominal voltage has a coil resistance of 30,000 Ohms and a pick-up voltage of 184V AC.

Relay Socket Assembly:
The relay socket assembly includes a socket terminal layout with specific terminal sets for different relay configurations. Dimensions are provided in millimeters, and the assembly includes a retaining clip for secure mounting.

Applications:
These relays are suitable for industrial control, instrumentation, automation, battery chargers, and power conditioning equipment.

Ordering Information:
The ordering code is structured as follows: Product Series - Number of Poles - Nominal Voltage - Specialties (if any). For example, 3R-3-230-XXX.

Additional Features:
Optional features include a free-wheeling diode, DIN rail mounting socket, and LED indication.
