The 10 kA breaking capacity, certified to both EN 60898 and IEC 60947-2, tells you it can safely interrupt a fault current up to 10,000 A at 400 V without welding its contacts or cascading upstream. That's the figure that governs selectivity coordination with the upstream device. Operating temperature spans -40 to 75 °C, covering unheated utility rooms and outdoor enclosures in cold climates.

Frequently asked questions
How do I get current pricing and availability for 5SL4304-7?
The 5SL4304-7 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
What is the closest functional second-source for 5SL4304-7?
The peer 5SL4363-7 shares the same SENTRON family, 3-pole C-curve design, 400 V AC rating, and 10 kA breaking capacity. The difference is the current rating — 5SL4363-7 is a 63 A unit versus the 4 A of 5SL4304-7. Panel footprint (76 mm depth, 54 mm width, 90 mm height) and DIN-rail mounting are identical, so it drops into the same enclosure without rewiring the busbar layout.
What is 5SL4304-7's listed depth?
The 5SL4304-7 has a depth of 76 mm, an installation depth of 70 mm, a width of 54 mm (3 modular units), and a height of 90 mm.
What compliance documentation does this brand provide for 5SL4304-7?
The 5SL4304-7 is halogen-free and silicon-free. It carries a degree of pollution 2 rating and overvoltage category III. The breaking capacity is certified to both EN 60898 and IEC 60947-2. The product is sealable for tamper-proof installations.
