Eaton Cutler-Hammer XTOBP40CC1 Overload Relay
The Eaton Cutler-Hammer XTOBP40CC1 is a precision-engineered bimetallic thermal overload relay designed for the XT series IEC contactors. Built for Frame C applications, this adjustable overload relay provides reliable motor protection within the 0.24-0.40 Amp full load current (FLA) range. It features a Trip Class 10 design, ensuring rapid response to phase loss and sustained overcurrent conditions, which is critical for protecting small horsepower motors in HVACR control panels. The unit includes built-in ambient temperature compensation and isolated 1NO-1NC auxiliary contacts for seamless integration into magnetic motor starter circuits. Designed for direct mounting to the contactor, it simplifies wiring and reduces enclosure footprint. Contractors rely on the XTOBP40CC1 for its consistent IEC 60947-4-1 compliance and its ability to prevent localized overheating in sensitive industrial and commercial blower and pump motors without frequent nuisance tripping.
Key Benefits for Technicians- Direct Mounting: Mounts directly to Frame C magnetic contactors for a compact and secure electrical connection.
- Selectable Reset: Adjustable between manual and automatic reset modes to suit specific industrial automation safety protocols.
- Phase Loss Sensitivity: Enhanced protection against single-phasing conditions that can lead to rapid motor winding failure.
- Transparent Cover: Features a sealable cover over the FLA adjustment dial to prevent unauthorized tampering in the field.
What is the difference between Trip Class 10 and Class 20 for this relay?
The XTOBP40CC1 is a Class 10 relay, meaning it will trip within 10 seconds or less at 600% of the maximum current setting, making it ideal for standard motor loads with typical startup times.
Can this relay be used with a 3-phase motor on a single-phase supply?
Yes, provided the proper wiring configuration is followed. In single-phase applications, all three poles of the bimetallic overload must be wired in series to ensure accurate thermal sensing and avoid premature tripping.
Does this unit require a separate mounting base?
For direct mounting to a compatible Eaton XT contactor, no additional base is required. However, for DIN rail mounting or standalone installation, a separate terminal block adapter is necessary.
