ABB S300P Miniature Circuit Breaker, 3-Pole, 4A, Type C, 415V ac AC, 125 V dc DC, 100 kA Breaking Capacity

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.

• 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

• 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

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

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

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

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