Product Information
Full details
This ABB Auxiliary Contact Block (model 1SAM 201 902 R 1001) is designed for professionals working with ABB switch/automat series MS 116, particularly for motor protection applications. Its key benefit is providing reliable 1 break and 1 make contact for control circuits, ensuring operational feedback. A potential caveat is its specific compatibility with certain ABB series, requiring verification before purchase.

FAQs
What is the primary function of this auxiliary contact block?
It provides additional contacts (1 break, 1 make) that mirror the status of the main ABB switch/automat MS 116, used for signaling, interlocking, or remote indication in control circuits.
What is the maximum AC voltage this contact block can handle?
The contact voltage rating is up to 400 V AC.
What is the maximum DC voltage this contact block can handle?
The contact voltage rating is up to 220 V DC.
Can this block be used with any circuit breaker?
No, it is specifically designed for side mounting on the ABB switch/automat series MS 116.
What does AC-15 rating mean for this block?
AC-15 is a category of duty for control circuits. The 2.4A rating at AC-15 indicates the block's capability for controlling electromagnetic equipment like contactors or solenoid valves under specific operating conditions.
How do I determine if the 'make' or 'break' contact is suitable for my application?
A 'make' contact (normally open) closes when the main device is activated, while a 'break' contact (normally closed) opens. Choose based on whether you need a circuit to be completed or interrupted when the main device is in its primary state.
What is the operating temperature range?
The block operates reliably within an ambient temperature range of -25°C to +60°C.
Troubleshooting
Contact not switching
Verify that the auxiliary contact block is correctly mounted and wired. Check that the connected actuator on the MS 116 unit is properly engaging the contact mechanism. Ensure the control circuit powering the MS 116 is live.
Loose terminal connection
De-energize the circuit. Carefully re-tighten the screw terminal using an appropriate screwdriver. If the terminal appears damaged, consider replacing the contact block.
Block not mounting correctly
Confirm that you are using a compatible ABB MS 116 series device. Ensure no obstructions are present on the mounting surface of the MS 116 unit or the contact block.
Pros and Cons
Pros
- Reliable contact configuration for control circuits.
- Designed for integration with ABB MS 116 series.
- Supports motor protection applications.
- Durable screw terminal connections.
Cons
- Limited compatibility outside of the specified ABB series.
- AC-15 current rating of 2.4A may be insufficient for high-power control loads.
- Requires specific mounting on compatible devices.
Setup, Compatibility & Care
Setup:
- Ensure the main switch/automat series MS 116 is de-energized and isolated from power.
- Align the auxiliary contact block with the designated mounting points on the side of the MS 116 unit.
- Securely attach the block following the manufacturer's instructions for the MS 116 series.
- Connect the control wires to the screw terminals, ensuring proper stripping and tightening for a secure connection.
Compatibility:
- Primarily designed for use with the ABB switch/automat series MS 116.
- Verify compatibility with specific control system requirements and voltage/current ratings.
Care:
- Periodically inspect the screw terminals for tightness and ensure they are free from dust or corrosion.
- Clean the exterior of the block with a dry or slightly damp cloth; avoid harsh cleaning agents or solvents.
- Ensure the operating environment remains within the specified temperature range (-25°C to +60°C).
