Schneider Electric LR9D5567 Electronic Overload Relay 60-100 A

LR9D5567 electronic overload relay for large TeSys Deca contactors

The LR9D5567 is a Schneider Electric product listed in the datasheet as: thermal overload relays, TeSys Deca, 60 to 100A, class 20. The LR9D5567 is an electronic thermal overload relay for medium to large motors, built for the TeSys Deca LC1D115 and LC1D150 contactors. It combines a thermal model of the motor with phase-failure sensitivity and an alarm output. Seven Star LLC supplies the LR9D5567 in Oman and the GCC as an independent supplier based in Muscat.

Reading the reference: LR9D marks the electronic relay series, the digits 5567 mark the 60 to 100 A adjustment range (title: 60…100A, class 20). The relay needs a 24 V DC supply for its electronics, as the table shows.

Technical specifications of the LR9D5567

Adjustment, class and alarm behaviour

Adjustment range: 60 to 100 A. Overload class: Class 20 IEC 60947-4-1. Signalling: Alarm. Tripping thresholds: 1.05 ± 0.06 In alarm IEC 60947-4-1; 1.12 ± 0.06 In de-energisation IEC 60947-4-1. Phase-failure behaviour: Tripping in 4 s ± 20 % IEC 60947-4-1. Supply voltage: 24 V DC.

Class 20 means the relay allows a longer starting period than class 10, which suits motors with heavy loads such as fans, crushers and centrifuges. The alarm output warns before the trip so the operator can lighten the load, and a reset button and a stop button are on the front.

Contactor pairing and use of the LR9D5567 in a starter

The relay mounts under a large LC1D frame; the datasheet product compatibility list names the contactors and also circuit breakers where it is used with separate mounting. Always check the compatibility list against the contactor.

The 1 NO plus 1 NC auxiliary contact of the relay is wired into the contactor coil circuit so that a trip drops the contactor, and the alarm contact can signal to the control system.

The datasheet downloaded for this page carries lifecycle notices: To be discontinued on: Dec 31, 2026. For a plant that already runs this reference that makes the LR9D5567 a spare-and-replacement item, and it is worth fixing the stock level and the long-term successor plan at the same time. We can discuss compatible alternatives once we know the installation.

Selection and ordering checklist for the LR9D5567

• Motor full-load current inside 60 to 100 A with room for adjustment.
• Class 20 versus class 10 for the starting time of the load.
• 24 V DC supply available in the panel.
• Contactor frame that accepts this relay.
• Alarm versus trip wiring in the control scheme.
• Lifecycle notice in the datasheet: plan the successor.

Setting, testing and maintenance of the LR9D5567

Mount the relay under the contactor, connect the power conductors to its bars, wire the auxiliary and alarm contacts to terminals, and apply the 24 V DC supply. Set the current dial to the motor nameplate current, not above it.

Test the trip with the test function and check the reset behaviour. In hot panels, remember the temperature compensation limits of the relay and keep the cabinet cool to avoid nuisance trips.

Typical applications of the LR9D5567 in Oman and the GCC

Large motors in water-treatment, desalination, oil and gas pump stations and ventilation units in Oman and the GCC are typical users. The electronic relay is preferred over bimetal types on motors that start often or in hot rooms.

Dimensions, environment and approvals of the LR9D5567

For the LR9D5567, plan the mounting space from the datasheet: 115 mm (W) x 118 mm (H) x 125 mm (D). The LR9D5567 weighs 0.885 kg.
