Product Information
Full details
This guide is for electricians and technicians working with electrical control systems. The ABB 1SBN010010R1010 terminal block offers reliable single-pole connection for auxiliary functions. A potential caveat is its specific single-level terminal design, which may require careful planning in complex wiring setups. It features a compact, front-mount design with one Normally Open (NO) instantaneous contact, screw terminals, and compatibility with ABB A and N series contactors.

FAQs
What does '1 Normally Open (NO)' mean?
It means the contact is open (not conducting electricity) when the associated device (like a contactor) is in its default, de-energized state. When the device is activated, this contact closes, allowing current to flow.
What types of ABB devices is this terminal block compatible with?
This terminal block is designed for use with ABB A series contactors and N series contactor relays.
Can this terminal block be used for high current loads?
No, this terminal block is intended for auxiliary control and signaling circuits, not for switching main power loads. It is not rated for high current.
What is the width of this terminal block?
The width of the ABB 1SBN010010R1010 terminal block is 9.5 mm.
How is the terminal block attached to the contactor?
It is a front-mount type, meaning it attaches directly to the front of compatible ABB contactors or relays.
What is the rated frequency for this terminal block?
The rated frequency for this terminal block is 60 Hz.
Troubleshooting
Terminal block not functioning (NO contact remains open)
Verify that the terminal block is correctly mounted to a compatible ABB device. Ensure the associated contactor or relay is properly energized. Check wiring connections to the screw terminals for tightness and correct polarity if applicable.
Loose wire connection at screw terminal
De-energize the circuit. Use a suitable screwdriver to re-tighten the screw terminal. Ensure the wire conductor is properly stripped and inserted fully before tightening.
Difficulty mounting the terminal block
Confirm that you are using a compatible ABB contactor or relay model. Ensure no obstructions are present on the mounting surface of the base device. Refer to the installation manual for the specific contactor/relay.

Setup, Compatibility & Care
Setup:
- Ensure the power supply to the associated contactor or relay is de-energized.
- Align the terminal block with the mounting points on the front of a compatible ABB A series or N series contactor/relay.
- Securely attach the terminal block following the manufacturer's instructions for the base device.
- Connect wires to the screw terminals for the NO contact, ensuring a firm connection.
Compatibility:
- This block is designed for use with ABB A series contactors and N series contactor relays.
