SQUARE D
SQUARE D LRD07L Overload Relay 1.6-2.5A 690V AC Trip Class 20
Thermal overload relay with 1.6-2.5A range, 690V AC rating, Trip Class 20, and direct contactor mounting
- Protects motors from 1.6 A to 2.5 A overloads with Trip Class 20 response
- Handles up to 690 V AC for demanding three-phase applications
- Offers both automatic and manual reset options for flexible recovery
- Mounts directly to TeSys Deca contactors using screw-clamp terminals
- Provides 1 NO and 1 NC auxiliary contacts for control-circuit signalling
Square D LRD07L Overload Relay 1.6-2.5A
This Square D LRD07L is a thermal overload relay designed for motor protection in industrial control panels. It mounts directly to a TeSys Deca contactor using screw-clamp terminals for secure wiring. The unit provides 1NO and 1NC auxiliary contacts for signalling or interlocking. It suits maintenance engineers and panel builders who need reliable overload protection for three-phase motors.
Trip Class 20 thermal protection range
The relay offers an adjustable current setting from 1.6 A to 2.5 A with a Trip Class 20 response time. It is rated for a maximum voltage of 690V AC across three poles. The thermal mechanism trips on sustained overcurrent and can be reset manually or automatically depending on the application requirement. This specification determines whether the relay matches the motor full-load current and the desired tripping characteristic.
Suits TeSys Deca contactors up to 2.5 A
This relay fits builders using TeSys Deca contactors who need overload protection in the 1.6 A to 2.5 A window. It is not for installations requiring a different current range, a different trip class, or a relay that mounts separately from the contactor. Buyers needing higher current settings, electronic overload functions, or a different mounting style should look at alternative devices.

Questions about this item
What does the 2.5 A maximum current setting mean when the relay is installed in a motor circuit?
The relay will trip to protect the motor if the current exceeds 2.5 A for a duration defined by Trip Class 20, which allows a longer acceleration period before tripping.
How does the 690V AC rating affect the contactor it can be mounted on?
The relay is rated for 690 V AC maximum, so it must be paired with a contactor whose coil and main contacts are also rated for at least 690 V AC to match the system voltage.
What contactor series and mounting method does this relay require?
It mounts directly onto TeSys Deca series contactors using screw clamp terminals, with no separate base or DIN-rail adapter needed.
