£105.92
The ABB 2CDS381103R0537, also designated the S301P-K32NA, is a high-performance miniature circuit breaker (MCB) from the proven ABB System pro M Compact S300P series. Designed specifically for industrial electrical installations, it provides dependable protection against overloads and short circuits whilst ensuring reliable operation in demanding environments.
Manufactured to international IEC, UL and CSA standards, the S301P-K32NA features ABB's patented fail-safe terminal technology, clear trip indication and compact DIN rail mounting. It combines high interruption performance with straightforward installation, making it ideal for industrial control panels, machinery and power distribution systems.
With a 32 A rated current, a Type K tripping characteristic, a 1P+N configuration and a 25 kA breaking capacity, the ABB 2CDS381103R0537 is particularly suited to motors, transformers, solenoids and other inductive loads that generate high inrush currents.
Type K miniature circuit breakers are specifically designed for circuits supplying motors, transformers, contactors and other inductive equipment that draw high inrush currents during start-up. Their magnetic tripping characteristic allows higher temporary starting currents whilst still providing rapid protection against genuine short-circuit faults.
The ABB S301P-K32NA combines this specialised protection with ABB's high-performance S300P platform, delivering excellent interruption capability, dependable long-term reliability and reduced nuisance tripping in demanding industrial applications.
