1SVR405651R3100

What type of component is this?

It is a logical relay socket from ABB’s CR-P Series, intended for use with compatible CR-M miniature relays.

What is the main function of this relay socket?

The socket provides the mechanical and electrical interface between a compatible CR-M relay and the control-panel wiring. It allows the relay to be plugged into a wired base rather than connected directly.

Which relays can be used with this socket?

It is designed for compatible CR-M miniature relays with 2 changeover or 4 changeover contact arrangements. The relay pin configuration should be checked before installation.

What type of electrical connections does it use?

The socket uses screw terminals, enabling conductors to be secured directly to the terminal points.

Does the socket provide switching contacts by itself?

No. The socket is an interface accessory and does not provide an output or output signal on its own. Its switching function depends on the compatible relay fitted to it.

What are the dimensions of the socket?

The unit measures approximately 27 mm wide, 61 mm high and 82 mm deep.

How much does the socket weigh?

The net weight is approximately 0.066 kg, or 66 g.

Can accessories be fitted to this socket?

Yes. Compatible pluggable function modules, a relay holder and a marker are available for the CR-M socket arrangement.

What is the purpose of the relay holder?

A compatible holder helps retain the plugged-in relay within the socket, supporting a secure and organised control-panel installation.

Can the socket be labelled for panel identification?

Yes. A compatible marker can be added so that the relay position or circuit reference can be identified within the control cabinet.

Is this a relay or a relay accessory?

It is a relay accessory rather than a complete relay. ABB 1SVR405651R3100 must be combined with a suitable CR-M miniature relay to create a functional switching assembly.

Is the socket compliant with RoHS requirements?

The product documentation states that it follows EU Directive 2011/65/EU regarding restrictions on specified hazardous substances.

How is this component classified?

It is classified as a relay socket under ETIM code EC001456 and is categorised within interface relays and optocouplers.

Where is this socket commonly used?

It is commonly used in industrial control panels, machine control circuits, building control systems and automation cabinets where a removable miniature relay interface is required.

What should be checked when selecting a compatible relay?

Check the CR-M relay series, contact arrangement, pin layout, coil voltage and application requirements. The socket provides the interface, while the fitted relay determines the coil and switching characteristics.
