ABB S300P Series Miniature Circuit Breaker, 20A Current, 415V ac rated voltage - 2CDS383001R0204

This miniature circuit breaker provides overcurrent protection for three-phase electrical installations and is designed for DIN-rail mounting in control panels. It interrupts fault currents up to its rated breaking capacity while accommodating both AC and DC systems, and is intended for use where Compact protective switching and manual reset operation are required.

Features and Benefits:

• 25 kA breaking capacity gives effective fault-current interruption
• 20 A current rating supports moderate load circuits
• Type C tripping characteristic protects against moderate inrush currents
• Three poles enable simultaneous disconnection of three conductors
• Toggle reset with screw terminals allows straightforward installation

Applications

• Suitable for three-phase distribution boards in commercial sites
• Ideal for motor-feeder protection with moderate start currents
• Used with DC control circuits up to the specified voltage
• Can be used for DIN-rail sub-distribution in switchgear
• Suitable for retrofit in Compact electrical enclosures

What mounting method does it use?

It clips onto a standard DIN rail for quick panel installation.

How is the device wired at each pole?

Each pole uses a screw Terminal for conductor connection and mechanical retention.

What environmental protection does the enclosure provide?

The unit has defined protection ratings of IP40 and IP20 for different faces.

Which standards does it meet for industrial and domestic use?

It conforms to IEC/EN 60947-2 and IEC/EN 60898-1 among other listed approvals.

What DC and AC voltages can it handle?

It is rated for operation up to 125 V dc and up to 415 V ac.
