Product details

Trip Class Selection for Motor Start Profiles

Matching the trip class to the motor start profile – 5E for fast starts, 30E for high-inertia loads – is the primary selection decision when specifying the Schneider LR9G500 electronic overload relay for 125-500 A circuits.

Direct Mount on TeSys Giga

The LR9G500 mounts directly onto the TeSys Giga contactor, saving panel space with its 5.51 in depth and IP20 protection; auxiliary contacts 1NO/1NC are built in.

Active Lifecycle and Availability

As an active product with strong aftermarket demand, the LR9G500 is readily available through distribution channels; plan for standard lead times on this high-turnover part.
