Product details

Rated 400 V AC, it handles single-phase branch circuits in industrial control panels up to that line voltage. Breaking capacity is the key fit number: 6 kA per EN 60898 for residential-style distribution, 30 kA per IEC 60947-2 for industrial panelboards, 15 kA at DC per IEC 60947-2, and 5 kA under UL 1077/CSA C22.2 No.235. The UL 1077 rating at 5 kA confirms it is recognized as a supplementary protector in North American panels, not a branch-circuit rated device under UL 489.

Mounting position is unrestricted, and the supply cord can enter from any side.

Halogen-free and silicon-free construction — important for environments where outgassing could contaminate optics or sensitive electronics. Sealable (can be locked in OFF position with a padlock) for lockout/tagout procedures.

Frequently asked questions

How do I get current pricing and availability for 5SY6102-8?

Submit an RFQ through this listing. We source the part to order; availability and current pricing are confirmed at quote time.

What is 5SY6102-8's listed depth?

76 mm overall depth; installation depth (behind the panel face) is 70 mm.

What compliance documentation does this breaker carry?

It carries ratings per EN 60898 (6 kA), IEC 60947-2 (30 kA AC, 15 kA DC), and UL 1077 / CSA C22.2 No.235 (5 kA). Halogen-free and silicon-free per the spec. RoHS/REACH documentation is standard with the brand.

Will 5SY6102-8 drop into a panel specified around 5SY6140-6CC without rewiring?

Both are 1-pole SENTRON MCBs on the same 18 mm DIN-rail footprint, so mechanical fit is identical. The difference is electrical: 5SY6102-8 is a 2 A D-curve; 5SY6140-6CC is a 40 A C-curve. Rewiring is required because the conductor sizing and load protection differ — the breaker itself clips into the same slot.
