Schneider BKF101 Single Contact Block

The Schneider BKF101, also cataloged as the BKF101 single contact block, operates as a dedicated hardware component for auxiliary circuit switching and control panel interlocking tasks within industrial automation systems.

Hardware Specifications

I/O density scaling

The Schneider BKF101 is engineered for modular integration within dense push button stations and control console assemblies, facilitating efficient I/O density scaling without increasing panel footprint requirements. The slow-break contact mechanism incorporates a positive opening operation, ensuring mechanical separation of the moving contact elements even in high-vibration environments. Dual termination options—comprising both screw clamp terminals and 6.35 mm Fast-on tabs—allow flexibility in wiring configurations while maintaining secure electrical continuity across automated machine architectures.

Frequently Asked Questions

Q: What is the maximum tightening torque recommended for the screw terminals?

A: The screw terminals require a tightening torque between 0.8 N-m and 1.2 N-m to ensure secure conductor retention without damaging the internal brass housing.

Q: Does the BKF101 support hot-swapping or live wiring changes?

A: No. Electrical power must be fully isolated from the control circuit prior to installing, removing, or wiring the contact block to prevent electrical shock or arc flash hazards.

Q: What wire gauge sizes are compatible with the screw clamp terminals?

A: The screw clamp terminals accept solid or stranded copper conductors ranging from AWG 22 to AWG 14 (0.5 mm squared to 2.5 mm squared).

Field Installation Guidelines

1. Power Isolation: De-energize all control circuits and associated power feeds before handling any panel components.
2. Actuator Alignment: Align the contact block mounting clips with the rear of the compatible XB4, XB5, or XB6 operator head and snap firmly into place until the locking latch engages.
3. Conductor Preparation: Strip insulation to the appropriate length for screw clamp or Fast-on connection, ensuring no stray wire strands create short circuits.
4. Torque Verification: Tighten terminal screws strictly within the 0.8 N-m to 1.2 N-m range using a calibrated torque screwdriver.
