ABB S300P Series Miniature Circuit Breaker, 6A Current, 25kA breaking capacity - 2CDS383001R0065

This miniature circuit breaker provides overcurrent protection for three-pole installations in electrical distribution equipment. It is designed for DIN-rail mounting and offers switching and fault interruption across AC and DC systems. The device uses a toggle reset actuator and screw terminals to connect conductors, and it is intended for environments requiring enclosed protection levels.

Features and Benefits:

• 6A current rating protects low-current circuits from overloads
• 25kA breaking capacity enables high fault-current interruption
• Type B tripping responds to low inrush loads and prevents nuisance trips
• 125V DC rated performance supports DC applications up to that voltage
• 415V AC compatibility allows use on standard low-voltage AC networks

Applications

• Suitable for three-phase distribution panels using DIN rail
• Ideal for protecting lighting circuits with low inrush currents
• Used for small motor protection where Type B curve applies
• Suitable for DC control circuits up to 125V DC
• Used in assemblies requiring screw-terminal connections

How many poles does the device provide and what does that mean?

It offers three poles, enabling simultaneous disconnection of three conductors in multi-phase circuits.

Which mounting style is required for installation?

It is intended for DIN-rail mounting, allowing Rapid Snap-on installation into standard enclosures.

What ingress protection levels are available and why are they relevant?

The unit is rated IP20 and IP40, indicating protection against access to live parts and varying degrees of solid-object ingress for enclosed installations.

Which standards and approvals does it conform to for electrical safety?

It meets IEC/EN 60947-2 and IEC/EN 60898-1 as well as UL1077 and CSA 22.2 No.235 among listed standards.

What Terminal and reset types are provided for user access?

Connections are via screw terminals and resetting is carried out with a toggle actuator.
