Spec SheetThe Square D TeSys Deca thermal overload relay is designed for protecting three-phase motors up to 3kW at 400V. It operates at 8A/690V with a thermal setting range of 5.5-8A and a tripping class of 20. The device includes a thermal adjustment dial, manual-automatic reset selector, test function, reset and stop buttons, a fault indicator flag, and two auxiliary contacts (1NO+1NC) for fault signaling. Settings are protected by a transparent, lockable cover. Connection is made via screw clamp terminals suitable for flexible or solid cables within specified ranges. Mounting options include DIN rail or screw fixing, with optional terminal block for separation from contactor connections. Certified for IEC, UL, CSA, and Marine standards, this relay is suitable for various control and protection applications.
