Product details

What this 4 A C-curve MCB does in the panel

The Siemens SENTRON 5SL6204-7MB is a 2-pole miniature circuit breaker rated 4 A with C-curve tripping characteristic, breaking 6 kA per EN 60898 at 400 V AC. The C-curve (5 to 10× In magnetic trip) handles moderate inrush from small motor loads, lighting banks, and transformer-coupled gear without nuisance tripping. Two poles switched together, 2 MW wide, snaps onto standard DIN rail.

Any mounting position. IP20 with connected conductors — intended for enclosed distribution boards, not exposed washdown areas. Sealable to prevent tamper after commissioning.

Frequently asked questions

What is the breaking capacity of 5SL6204-7MB?

6 kA per EN 60898 at 400 V AC. That is the rated short-circuit capacity for this 2-pole C-curve 4 A breaker.

What is the closest functional second-source to 5SL6204-7MB?

The Siemens 5SL4363-7 is a 3-pole version with 10 kA breaking capacity and a wider 54 mm footprint — it will not drop into the same 2-MW panel cutout without rewiring and a wider DIN rail slot.

What compliance documentation does this brand provide for 5SL6204-7MB?

The SENTRON series carries standard IEC/EN 60898 certification for miniature circuit breakers. Halogen-free and silicon-free construction is specified on this variant.

Where can I buy 5SL6204-7MB and get current pricing?

Sourced and quoted to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time.
