The ABB S2C-H11L Auxiliary Contact is designed for users of ABB S200 series Miniature Circuit Breakers (MCBs) who need a clear visual indication of the MCB's contact status. Its key benefit is providing immediate feedback on whether the MCB is open or closed, enhancing operational awareness. A potential caveat is its specific compatibility, requiring it to be mounted on the left side of S200 series MCBs only.

FAQs
What is an auxiliary contact used for?
An auxiliary contact provides remote indication or control based on the status of a primary device, such as a circuit breaker. It signals whether the breaker is open or closed, or can be used to enable/disable other circuits.
Which ABB MCB series are compatible with the S2C-H11L?
The S2C-H11L is compatible with the ABB S200, S200M, S200P, and S200S series Miniature Circuit Breakers.
Can I mount this auxiliary contact on the right side of an MCB?
No, the S2C-H11L is specifically designed to be mounted on the left side of the compatible MCB.
What is the electrical rating of the S2C-H11L?
The auxiliary contact is rated for a maximum of 10 Amps and 24 Volts AC/DC.
What does NC/NO configuration mean?
NC stands for Normally Closed, meaning the contact is closed when the MCB is in its default (un-tripped) state. NO stands for Normally Open, meaning the contact is open when the MCB is in its default state. The S2C-H11L provides one of each.
How do I install the S2C-H11L?
Ensure the MCB is de-energized, align the contact to the left side of the MCB, and clip it securely into place. Then, wire the NC and NO terminals as needed for your application.
Can this be used with MCBs other than the S200 series?
No, it is designed and tested only for compatibility with the specified S200, S200M, S200P, and S200S series MCBs.
Troubleshooting
Auxiliary contact not providing a signal
Verify that the MCB is in the correct position (ON/OFF) and that the auxiliary contact is securely attached. Check your wiring connections to the NC/NO terminals and ensure they are correct for your application. Confirm the MCB is compatible (S200 series) and correctly mounted on the left side.
Device appears loose or does not clip on properly
Ensure you are attempting to mount it on the correct side (left) of a compatible S200 series MCB. Check for any obstructions or damage to the mounting clips on either the MCB or the auxiliary contact.
Contact status indication is inconsistent
Inspect the wiring connections for tightness. Ensure the rated voltage and current (24V AC/DC, 10A) are not exceeded. A faulty MCB may also cause inconsistent signaling.
