Product details

The 5SP4292-6: Snaps onto DIN rail or screws direct to the panel backplate — both fixing methods are listed. Mount in any position; the installation depth behind the panel is 70 mm. Terminal tunnels top and bottom accept conductors up to the rating, and the unit is sealable for applications that need tamper-evident covers.

Temperature derating is baked into the spec: 125 A at 30 °C, 118.75 A at 40 °C, 115 A at 45 °C, 111.875 A at 50 °C, 108.75 A at 55 °C, 105 A at 60 °C. Pollution degree 3, overvoltage category III, shock resistance 150 m/s² at 11 ms half-sine per IEC 60068-2-27.

Lifecycle status is current — no phase-out, no last-time-buy window active. For compliance documentation, the SENTRON series typically carries CE, UL, and CSA marks; verify the specific certification package with the order confirmation if your QA requires it for the panel.

Frequently asked questions

Where can I buy 5SP4292-6 and how do I get a price?

Sourced to order against an RFQ through independent distribution. Submit a request for quote; availability and current pricing are confirmed at quote time.

When sourcing 5SP4292-6, what's the closest functional second-source — 5SP4292-7?

The 5SP4292-7 is the same 2-pole SENTRON platform but with a C-curve trip characteristic (5–10× In) instead of the B-curve on the -6. If your load type (motor inrush, transformer) needs the higher magnetic threshold, the -7 is a direct mechanical swap — same footprint, same DIN-rail mount, same terminal layout. For resistive or general-purpose loads, stick with the B-curve -6.

Will 5SP4292-6 drop into a panel that was specified around 5SP4292-7 without rewiring?

Yes — both share the same 2-pole housing, 3 MW width, DIN-rail/screw fixing, and tunnel terminals top and bottom. No rewiring needed. The only difference is the trip curve: B (3–5× In) on the -6 vs C (5–10× In) on the -7.

What compliance documentation does this brand provide for 5SP4292-6 (RoHS, REACH, UL, IEC)?

The SENTRON series is designed to EN 60898 and IEC 61346-2 / IEC 81346-2 standards. The unit is halogen-free and silicon-free. For specific RoHS/REACH declarations and UL/CSA certification copies, request them with your order — they are typically available from the manufacturer's documentation portal.
