The ABB S202K2A is a supplementary trip device classified under Circuit Breaker Accessories, specifically a Circuit Breaker Trip Device. It sits within the broader category of Circuit Breakers, Fuses & Protection. This is the component that mounts inside or alongside a breaker to provide overcurrent or short-circuit trip functionality, not the breaker itself — a distinction that matters when you're pulling a BOM line for a panel rebuild and the main breaker is already specified.

Frequently asked questions
Where can I buy the S202K2A and what is the lead time?
The S202K2A is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for the latest lead time.
What is the closest second-source to the S202K2A — the S261-B32?
The S261-B32 is the closest peer in the same category. However, the S202K2A weighs 0.29 kgs versus 0.14 kgs for the S261-B32, indicating different internal construction. Verify mechanical fit and trip coordination before substituting.
Will the S202K2A drop into a panel specified around the S261-B32 without rewiring?
Not necessarily. The S202K2A is over twice the weight of the S261-B32 (0.29 kgs vs 0.14 kgs), suggesting different internal components. Check the mounting footprint, terminal layout, and trip curve before assuming a direct swap.
