Product details

Curve C and selectivity

Trip Curve C means the magnetic trip fires at 5 to 10 times rated current (125–250 A for this 25 A unit). In a panel coordinated for Curve C downstream, this breaker holds selectivity with a 63 A or 80 A upstream Curve C MCB up to roughly 6 kA fault level, depending on the manufacturer's let-through chart.

Panel integration

The 3-pole body occupies three modular units (17.5 mm each). Busbar comb can be inserted from the top or bottom; the terminal screws are captive and require a Pozidriv #2 bit.

Frequently asked questions

How do I get current pricing and availability for S203P-C25?

Submit an RFQ for the S203P-C25. Availability and current pricing are confirmed at quote time through our independent distribution network. No stock count or price is published here.

What is S203P-C25's listed amps (25) on this component line?

The S203P-C25 is rated 25 A continuous current. That's the thermal rating for the full 3-pole assembly at 40 °C ambient — no derating needed for standard panel conditions.

What is S203P-C25's listed type (Trip Curve C) on this component line?

Trip Curve C means the magnetic trip operates at 5 to 10 times rated current. For the 25 A unit, that's 125–250 A instantaneous trip — suited for general-purpose loads with moderate inrush.

Will S203P-C25 drop into a panel that was specified around S203-D13 without rewiring?

Yes, mechanically and electrically it fits the same footprint — both are 3-pole DIN-rail MCBs rated 277 V AC with 10 kA interrupting capacity. The difference is the trip curve: Curve C (S203P-C25) vs Curve D (S203-D13). If the original design specified Curve D for motor-starting inrush, swapping to Curve C may cause nuisance tripping on start-up. Verify the load type before substitution.
