Product information

Description

Schneider Electric LRD21 is a thermal overload relay designed to detect and interrupt motor overload conditions. With a specified coil voltage of 690 V and a compact, multicolour enclosure, the unit provides thermal protection suitable for integration into motor starters and control panels in industrial and commercial installations. The relay's lightweight construction (124 g) and standard form factor make it straightforward to mount alongside contactors and other control equipment.

Advantages

The LRD21 offers reliable thermal sensing to protect motors from sustained overloads and potential damage. Its design supports straightforward installation in existing motor control assemblies and ensures consistent performance at the specified coil voltage. The compact size and low weight reduce space and mounting requirements while the multicolour finish helps with visual identification during wiring and maintenance.

Suitable for

  • Protection of small to medium AC motors in industrial control panels
  • Integration with motor starters and contactor assemblies
  • Commercial HVAC and pump motor protection
  • Retrofit and replacement of compatible thermal overload relays

Key specifications

  • Function: thermal overload protection for motors
  • Rated coil voltage: 690 V
  • Finish: multicolour housing
  • Weight: 124 g
  • Mounting: panel or contactor-adjacent installation (standard relay form factor)

How to use

Install the relay according to the motor starter and control panel manufacturer's instructions, ensuring correct electrical isolation before wiring. Mount the LRD21 adjacent to the contactor or in the designated relay slot, connect the supply and motor conductors to the appropriate terminals, and set any adjustable current or trip settings if applicable. Verify that the coil voltage matches the control circuit rated 690 V and perform functional tests to confirm correct tripping behavior under simulated overload conditions.

Usage recommendations

Confirm compatibility with the motor's full-load current and the control circuit voltage before installation. Use the relay within its rated electrical environment and follow routine maintenance checks, including terminal tightening and visual inspection of the housing to ensure reliable long-term protection.
