Construction
Actus MSAR relayTechnical specifcations
Te Actus relays represents a new generation o electro-mechanical relays designed specically orapplication where high perormance and reliability is paramount. While the undamental andproven electro-mechanical mechanism has been maintained, the implementation o modernmanuacturing techniques combined with an innovative architecture has provided a very exibleand competitive alternative to older generation auxiliary relays.
Te drawing on the let provides a snap shot o the major design innovations incorporated in theserelays.
Inspection o the contacts is possible by drawing out the relay module rom the case as shown on
the right. Te contacts, while protected and isolated at the rear terminal block o the module arereadily visible so that they can be checked or any sign o burning, pitting or overheating.
Manual operation o the contacts is also possible with the module removed rom the case. Tisallows checking o the contact alignment and over travel.

Contact operationSel reset contacts All contacts operate when a voltage in the specied range is applied to the relay coil
and reset when this voltage is removed.
Latching contacts - hand reset Hand reset
All contacts operate and mechanically latch when a voltage in the specied range is
applied to the relay coil and reset when the reset button located on the ront o the
relay is pressed.
Electrical and hand reset
All contacts operate and mechanically latch when a voltage in the specied range
is applied to the relay coil and reset when the reset button located on the ront othe relay is pressed. A voltage applied to the reset coil may also be used to reset the
contacts.

Contact perormance
Actus MSAR relayTechnical specifcations
Sel cleaning contacts Contacts are constructed rom silver / copper alloy, specially shaped and positi-
oned to ensure very reliable, low resistance operation. Over travel o the contacts
during each operation causes a wiping action ensuring a clean make with minimal
bounce.
Double make / double
break contacts
Each contact is made up o a double make or double break geometry to increase
the isolation between open contacts and increase the current break rating.
Double make contacts picked up Double break contacts picked up
Tis geometry also removes the need or internal wiring between case terminals and
the relay contacts. Tis results in our (4) less electrical terminations per contact
providing increased system security.
Gold plated contacts Gold plated contacts are available as an option or very low current switching.Reer ordering code section.
Manual reset mechanism.For relays specied with manual reset unctions, a reset mechanism is provided on the ront paneland cover. Manual reset can be accomplished with the ront cover tted or removed.Care should be taken to avoid holding the contact and armature ag hand reset actuator in thereset position during the presence o a relay operate signal. Tis action will cause the relay to
oscillate between drop-out and pick-up and i this condition is maintained itmay result in thermaland mechanical damage to the device.
Coil operation LEDAn optional ront panel LED may be specied to indicate when a voltage is applied to the operatecoil terminals. Tis eature can be useul during commissioning particularly or latching relaysand where armature ags are not tted to indicate the operate voltage status. Reer ordering codesection.
Operation counterAn optional 6 digit operation counter is available to record the number o contact pick up events.Te displayed count cannot be reset. (not available on the MSAR25 version)

Flag indicatorsTe Actus MSAR relay oers two types o mechanical ags. Tese consist o a high visibility; solid, day glow
orange indicator which become visible on energisation o the relay coil. Te relay can be ordered with either,
both or no ags tted. Reverse acting ags are also available.
Note: Tere is no impact on the contact operate speed or relay perormance when these ags are tted.
Armature ag Te armature ag is connected to the relay armature and thereore always indicates
the position o the contacts. Te standard armature ag becomes visible when therelay is operated. I latching contacts are specied the sel reset ag will remain
visible in the latched condition until the relay is reset.
Independent hand reset
ag
Tis ag is independent o the sel reset ag and operates when the contacts are rst
operated and remains visible until it is manually hand reset using the reset button
located on the ront o the relay. Note that this ag can only be reset once the relay
has been reset.

Terminal block
Te draw out unction is made possible through the use o inner and outer terminal blocks, eachwith silver plated contact ngers to provide high current rating and very low electrical resistance.
A high quality molded inner terminal block is utilized which incorporates the switching contactsthus eliminating the requirement or internal wiring and in turn removing a potential circuit ailuremechanism.
M4 screw terminals allow 2x crimp lug connections per point. Space efcient design allows 28
contact points per terminal block.
