Product details

What this MCB carries and where

Breaking capacity is 10 kA per EN 60898 and 20 kA per IEC 60947-2; at DC (72 V) the interrupting rating is 15 kA per IEC 60947-2. For UL 1077 / CSA C22.2 No. 235 the AC rating is 5 kA. Energy limiting class 3 means the breaker clears a fault fast enough to let downstream equipment ride through a limited let-through energy — important for coordinating with downstream contactors or drives that have lower short-circuit withstand.

The housing occupies 4 width units (72 mm wide) and the total depth including terminals is 76 mm. With IP20 protection (with connected conductors) and overvoltage category III, it is suited for enclosure-mounted distribution boards in mechanical engineering and industrial environments. Touch protection is built into the design.

Frequently asked questions

What is the breaking capacity of 5SY4410-7KK11?

10 kA per EN 60898, 20 kA per IEC 60947-2 at 400 V AC; 15 kA at 72 V DC per IEC 60947-2; 5 kA per UL 1077.

Where can I buy 5SY4410-7KK11?

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

Will 5SY4410-7KK11 drop into a panel specified around 5SY4301-7CV without rewiring?

The 5SY4410-7KK11 is a 4-pole, 10 A C-curve MCB; the 5SY4301-7CV is a different variant. Both share the SENTRON DIN-rail footprint, but verify the rated current and tripping characteristic match your branch circuit before swapping.
