Product details

The 32 A continuous rating determines the maximum load this breaker can carry without tripping under normal conditions — sized for branch circuits feeding lighting, socket outlets, or small motor loads where the full-load current stays under 32 A. This suits predominantly resistive loads or short cable runs where inrush is low — common in lighting circuits and general-purpose socket outlets. It is not the right curve for motor starting (use Curve C or D for that).

Deployment context

Single-pole width (roughly 18 mm per module) means it occupies one position in a multi-way distribution board.

Frequently asked questions

What is the interrupting rating of the S201-B32?

The S201-B32 has a 6 kA interrupting rating at 277 VAC, meaning it can safely clear fault currents up to 6,000 A.

Where can I buy the S201-B32 and how is it quoted?

The S201-B32 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock count or price figure is published here.

What is the difference between S201-B32 and a 2-pole C-curve breaker like S202M-C25?

The S201-B32 is a 1-pole, 32 A, Curve B breaker; the S202M-C25 is a 2-pole, 25 A, Curve C breaker. The S201-B32 suits single-phase resistive loads with low inrush, while the S202M-C25 handles two-pole circuits and higher inrush (motor or transformer loads) due to its C-curve magnetic trip (5–10× rated). They are not drop-in replacements — poles, ampacity, and trip characteristic all differ.
