Why Choose the ABB 2CDS381001R0634 Miniature Circuit Breaker?

The ABB 2CDS381001R0634, also known as the ABB S301P-C63, is a high-performance miniature circuit breaker (MCB) designed to protect industrial electrical installations against overloads and short circuits. As part of the ABB System pro M compact S300P series, it combines high fault-breaking performance with compact dimensions and reliable operation.

This single-pole circuit breaker uses thermal and electromagnetic tripping mechanisms to provide effective protection for cables, machinery and connected equipment. An integrated trip indicator supports rapid fault identification, while the dual DIN rail release and fail-safe terminals help simplify installation and maintenance.

With a rated current of 63 A and a Type C tripping characteristic, the ABB 2CDS381001R0634 is suitable for general industrial and commercial circuits with moderate inrush currents. Its short-circuit breaking capacity is rated at 15 kA at 400 V AC under IEC/EN 60947-2, with ratings of up to 25 kA at lower operating voltages.

Key Advantages

  • High-performance miniature circuit breaker for industrial circuit protection.
  • 63 A rated current for demanding electrical loads.
  • Type C tripping characteristic suitable for moderate inrush currents.
  • 15 kA breaking capacity at 400 V AC under IEC/EN 60947-2.
  • Integrated trip indicator enables clear fault identification.
  • Dual DIN rail release supports quick installation and removal.

Key Features

  • ABB System pro M compact S300P series.
  • S301P-C63 miniature circuit breaker.
  • Single-pole configuration.
  • 63 A rated current.
  • Type C tripping characteristic.
  • Thermal overload and electromagnetic short-circuit protection.
  • Fail-safe terminals suitable for cables and busbars.
  • Compact 17.5 mm DIN rail mounted construction.

Reliable Circuit Protection for Industrial Installations

The ABB S301P-C63 automatically disconnects an electrical circuit when a sustained overload or short circuit occurs. This helps protect cables, distribution equipment and connected machinery while reducing the risk of electrical damage, fire and unplanned downtime.

Its Type C tripping characteristic is designed to accommodate the moderate starting currents produced by equipment such as small motors, lighting systems and transformers. This provides a practical balance between dependable fault protection and resistance to unnecessary tripping.

Typical Applications

  • Industrial control panels and switchboards.
  • Commercial electrical distribution systems.
  • Lighting and socket circuits.
  • Small motor and transformer circuits.
  • Machine building and OEM equipment.
  • Transportation and renewable-energy installations.
