Product details

The C-curve means the thermal-magnetic trip holds up to 5–10× rated current for short overloads, so it's sized for motor-starting or transformer inrush loads that would nuisance-trip a B-curve. The higher IEC figure applies when the RCBO is used as a distribution-board component in an industrial installation with a known prospective fault level; the EN number governs residential/commercial certification. Operating frequency is 50 Hz only; this is not a 50/60 Hz dual-rated unit, so confirm mains frequency before specifying.

That -40 °C floor matters for unheated enclosures in cold climates — the thermal-magnetic trip element stays within calibration down to that limit.

Frequently asked questions

How do I get current pricing and availability for 5SU1324-1RC63?

Submit an RFQ through this listing. The part is sourced through independent distribution; availability and current pricing are confirmed at quote time.

What is the closest functional alternative — 5SL4363-7?

The 5SL4363-7 is a Siemens SENTRON miniature circuit breaker (MCB), not an RCBO — it provides overcurrent protection only, with no residual-current element. The 5SL4363-7 is 3-pole, 63 A, C-curve, 3-module width, with a 10 kA breaking capacity per both EN 60898 and IEC 60947-2. If your application requires combined overcurrent and residual-current protection in one device, the 5SU1324-1RC63 is the correct choice; the 5SL4363-7 would need a separate RCCB upstream.

Will 5SU1324-1RC63 drop into a panel specified around 5SL4363-7 without rewiring?

No — the 5SU1324-1RC63 is 2-pole and 4-module wide (72 mm), while the 5SL4363-7 is 3-pole and 3-module wide (54 mm). The RCBO also requires a neutral connection for the residual-current circuit. The panel layout, busbar arrangement, and wiring would all need revision.

What compliance documentation does Siemens provide for 5SU1324-1RC63?

As a current-production SENTRON device, it carries CE marking per the Low Voltage Directive and EMC Directive, with a declaration of conformity available. RoHS and REACH compliance statements are standard. The product is designed to EN 60898 and IEC 60947-2.
