Schneider Electric 9065-TO1 Thermal Overload Relay

Schneider Electric's Square D 9065TO1 Thermal Overload Relay is a melting‑alloy overload device designed for NEMA size 2, 1‑pole motor protection. It is rated for up to 45 A and supports a maximum voltage of 600 VAC or DC, making it compatible with a wide range of motors and control circuits. As part of the 9065 family, the TO1 model provides thermal protection by tripping on sustained overloads, helping guard windings from heat damage in industrial panels. This compact relay is intended for motor protection within control panels and motor circuits, and should be sized by matching your motor's full‑load current to the 45 A rating while ensuring the system voltage does not exceed 600 V. The 9065TO1’s form factor and rating align with many Square D/Schneider Electric motor control installations, offering a straightforward option when a melting‑alloy overload relay is appropriate.
