Product details

The Siemens Betagard 5SL7332-8RC is a 3-pole miniature circuit breaker with a D tripping characteristic, rated 32 A at 415 V AC and a breaking capacity of 15 kA per both EN 60898 and IEC 60947-2. It occupies 3 modular width units (18 mm per unit, 54 mm total) on a DIN rail, with an installation depth of 70 mm and overall depth of 76 mm. Mounting position is unrestricted, so it can be laid flat or vertical in a panel without derating. Rated for 50/60 Hz AC systems up to 440 V maximum (multi-phase or single-phase), and built for industrial environments per its suitability designation. The D-curve and high breaking capacity make this a fit for motor branch circuits or transformer primary protection where the inrush is substantial and fault levels are high.

The Betagard series is Siemens' industrial-grade MCB line, distinct from the SENTRON residential/infrastructure range.

The breaker is sealable (provision for a lock or tagout device), which is expected for industrial isolation points.

Frequently asked questions

What is the breaking capacity of 5SL7332-8RC?

15 kA per both EN 60898 and IEC 60947-2 at 415 V AC. That rating is the same for both standards, so it's suitable for industrial panels where the fault current can reach that level.

What is the D-curve on this breaker for?

The D tripping characteristic (10-20x In) is designed for loads with high inrush currents such as motor starters, transformers, and capacitor banks. It avoids nuisance tripping on startup while still providing overcurrent protection.

Where can I buy 5SL7332-8RC?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

How does 5SL7332-8RC compare to the SENTRON 5SL4363-7?

The 5SL4363-7 is a SENTRON-branded MCB with a C-curve, 10 kA breaking capacity at 400 V, and a wider 54 mm width (3 modules). The Betagard 5SL7332-8RC has a D-curve, 15 kA at 415 V, and the same 54 mm width. The key difference is the tripping characteristic and breaking capacity — if your panel needs D-curve and higher fault interruption, the 5SL7332-8RC is the fit; if C-curve and 10 kA suffice, the 5SL4363-7 is an alternative but requires verifying the brand and series compatibility with your distribution board.
