Product details

The Siemens 5SL6425-6RC is a SENTRON 5SL6 miniature circuit breaker rated 25 A at 415 V AC, 4-pole, with a B tripping characteristic and a 7.5 kA breaking capacity per EN 60898. Four poles (4P) switch all four conductors — three phases plus neutral — so it's sized for a three-phase supply where the neutral needs overcurrent protection.

Where it goes — deployment context

This MCB is designed for residential buildings and infrastructure — think distribution boards in apartment blocks, small commercial premises, or utility sub-mains.

Frequently asked questions

Where can I buy 5SL6425-6RC and what is the lead time?

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 delivery commitment.

What is the breaking capacity of 5SL6425-6RC?

The breaking capacity is 7.5 kA per EN 60898 at 415 V AC. That's the maximum fault current the MCB can safely interrupt under standard test conditions.

What are the physical dimensions of 5SL6425-6RC?

The MCB measures 72 mm wide (4 width units), 90 mm high, and 76 mm deep (70 mm installation depth). Fits standard DIN-rail enclosures.

Will 5SL6425-6RC drop into a panel specified around 5SL4120-7CC?

Both are SENTRON 5SL series MCBs with the same 4-pole DIN-rail footprint, so physical fit is identical. The difference is rating: 5SL6425-6RC is 25 A B-characteristic 7.5 kA; 5SL4120-7CC is a different rating and characteristic. Verify the branch circuit's ampacity and fault level before swapping — the mechanical swap is straightforward, but the electrical ratings must match the design.
