XTOB057DC1 Eaton Overload Relay

The Eaton XTOB057DC1 is an IEC D-frame thermal overload relay with built-in overload protection, intended for motor protection across an adjustable 40 – 57 A current range. Its overload auxiliary contact system includes one normally open and one normally closed contact, supporting flexible integration into control circuits. Short-circuit protection extends up to 600 VAC, with ratings for 200 A fuses and 200 A circuit breakers. These protection ratings suit the stated industrial and commercial motor protection applications. UL and CSA certifications indicate compliance with international safety and performance standards. The D-frame XTOB057DC1 combines an adjustable thermal overload relay, integrated overload protection, auxiliary contacts, and short-circuit protection in one unit.
