ABB S300P Series Miniature Circuit Breaker, 4A Current, 415V ac Rated Voltage - 2CDS383001R0044

This miniature circuit breaker provides overcurrent protection for low-voltage installations and is intended for DIN-rail mounted distribution panels. It operates with a type C tripping characteristic suitable for moderate inrush currents and is rated for both AC and DC systems, allowing application in mixed-voltage environments where Compact protection is required. The device includes a toggle reset actuator and screw-type terminations for secure connections.

Features and Benefits:

• 25kA breaking capacity limits fault energy
• 3-pole configuration protects three conductors simultaneously
• Type C tripping copes with motor start-up surges
• Toggle reset actuator enables quick manual reclosure
• Screw terminals ensure secure conductor clamping

Applications

• Suitable for three-phase distribution protection
• Ideal for industrial control panels with DIN-rail
• Used with DC control circuits up to 125V dc
• Can be used for branch-circuit protection in machinery
• Used for installations requiring recognised standards approvals

What electrical approvals accompany the device?

It meets IEC/EN 60947-2 and IEC/EN 60898-1 standards and holds UL1077 and CSA22.2 No.235 approvals.

How does the product handle DC switching?

It is rated to interrupt circuits at 125V dc, allowing use in direct-current applications within that voltage.

What ingress protection is provided for the terminals and enclosure?

The unit offers IP40 protection for the enclosure and IP20 for accessible parts, restricting contact and particle entry accordingly.

What mounting and termination methods are required for installation?

It clips onto a standard DIN rail and uses screw-type terminals for conductor connection.
