Siemens 5SL7125-3RC, Miniature Circuit Breaker, 25A, 1-pole, K characteristic, 15kA breaking capacity.
The K curve is designed for motor and inductive loads, tripping between 10 and 14 times rated current, which avoids nuisance trips during inrush while still providing short-circuit protection. This makes it a fit for controlling and protecting individual motor circuits or transformer primaries in a distribution board.
The 1-pole format occupies a single DIN module width, so it fits standard 18 mm pitch enclosures.
The 5SL7125-3RC has a 15 kA breaking capacity, which is the maximum fault current it can safely interrupt.
The 5SL7125-3RC is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time.
Alternative models and sibling configurations in the same Siemens series. For obsolete or discontinued parts, these models can serve as compatible replacements or functional alternatives for plant maintenance.
