Product details

What this 1.6 A D-curve MCB is for

The Siemens 5SL4315-8CC is a 3-pole miniature circuit breaker rated 1.6 A with a D tripping characteristic, designed for 400 V AC systems and a 10 kA breaking capacity. On a 400 V three-phase panel, this breaker protects the downstream cable and load against short-circuit and overload, not the operator; it's a distribution-level device, not a personnel-protection RCD.

Three-pole, 1.6 A rating on a D-curve. Mounts on standard DIN rail in the distribution board. Terminal capacity accepts up to 25 mm² conductor — verify lug type against your panel's gland plate fill factor. The D-curve's magnetic trip range (10–20× In) means this breaker holds through a motor start but clears a bolted fault fast enough to coordinate with a 63 A upstream MCCB in a typical selectivity study.

Frequently asked questions

Where can I buy the 5SL4315-8CC and get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What does the D-curve mean on this 1.6 A breaker?

The D tripping characteristic means the magnetic trip activates at 10 to 20 times the rated current (16 A to 32 A), so it handles the inrush from motor starters, small transformers, or solenoid banks without nuisance tripping on startup.

What compliance documentation does Siemens provide for the 5SL4315-8CC?

The breaker is RoHS compliant since June 2013 and REACH candidate-list information is available from Siemens. Export control is AL: N / ECCN: N, meaning no special license is required for standard commercial shipments.

What are the group code and product group for the 5SL4315-8CC?

The Siemens group code is P310 and the product group is 3824. These are internal Siemens classification codes used for logistics and catalog organization.
