Trigger block standard design PKE-XTU-65 138259

Overload release block standard design PKE-XTU-65 – reliable motor protection

The PKE-XTU-65 overload release block is a component of the Eaton motor starter, providing comprehensive protection for electric motors. It replaces the traditional bimetallic overload element, offering precise and flexible protection settings. It is a key component for installers and users who need reliable protection against overloads and short circuits.

Functionality and application

The PKE-XTU-65 overload release block is designed to work with motor starters of the PKE series. It allows you to adjust the tripping characteristics to the specifics of the protected circuit, which is especially important for motors with variable loads or difficult starting. This ensures optimal protection for both the motor itself and the entire electrical installation. The ability to set the tripping class (5-20) allows precise adaptation to the type of motor: easy, normal, heavy or very heavy starting.

Advantages and benefits

• Setting flexibility: The adjustable range of the overload release (16…65 A) allows adaptation to different applications.
• Precise protection: The electronic release block provides a faster and more accurate response to overloads than traditional bimetallic solutions.
• Short-circuit protection: Two short-circuit poles – fixed in the basic device (15.5 x Iu) and time-delay in the release block (15.5 x Ir) – provide effective protection against the effects of short circuits.
• Versatility: Can be used as a main switch or emergency stop after connection with appropriate accessories, in accordance with EN 60204 and VDE 0113 standards.
• Durability: Short-circuit resistance up to 50 kA at 400V (for 65A current).
• Wide voltage range: Suitable for operation in AC networks with a voltage of 690 V (50/60 Hz) and DC with a voltage of 690 V.
• Compact dimensions: Height 69.9 mm, width 55 mm and depth 84.4 mm facilitate installation in confined spaces.
• Three-pole design: Designed to protect three-phase circuits with a rated continuous current of up to 65 A.

Thanks to these features, the PKE-XTU-65 overload release block is a reliable solution for a wide range of industrial and commercial applications, ensuring the safety and efficiency of electrical installations.
