ABB S300P Series Miniature Circuit Breaker, 20A Current, 3 Poles - 2CDS383001R0205

This miniature circuit breaker provides overcurrent protection for three-phase circuits in commercial and industrial installations. It is designed for DIN-rail mounting and operated via a toggle reset, offering straightforward manual control. The device accommodates both AC and DC systems, allowing use where mixed-voltage protection is required.

Features and Benefits:

• 25kA breaking capacity limits fault energy and reduces equipment damage
• Type B tripping characteristic MCB protects against low-level fault currents
• 125V DC rated MCB 3 pole permits use in DC power circuits
• 415V AC 20A circuit breaker screw Terminal supports typical industrial supplies
• IP20/IP40 miniature circuit breaker offers Basic ingress protection levels

Applications

• Suitable for distribution boards in light-commercial premises
• Ideal for protecting small motor circuits and lighting runs
• Used with DIN-rail enclosures in plant control cabinets
• Can be used for DC control circuits requiring 125V protection
• Suitable for replacement of three-pole protection devices in panels

What Terminal connection method is provided for installation?

Screw terminals are supplied to secure conductors and facilitate wiring.

How is the device mounted within electrical panels?

It is intended for DIN-rail mounting to integrate with standard distribution assemblies.

Which tripping behaviour does it offer for sensitive circuits?

It employs a Type B characteristic which trips on relatively low fault currents.

What manual control is available for resetting after a trip?

A toggle reset actuator is provided for manual reclosure of the circuit.

Which standards apply to its construction and testing?

It meets multiple international standards including IEC/EN 60947-2 and IEC/EN 60898-1.
