Product details

C-curve 2-pole MCB for panel builders

The Siemens SENTRON 5SY7263-7 is a C-curve miniature circuit breaker rated 400 V AC (440 V multi- or single-phase) and 60 V DC (max 72 V). Two poles, no neutral switching. Tripping characteristic C means it holds 5–10× rated current before instantaneous trip — standard for motor and lighting circuits where inrush is moderate. Breaking capacity hits 15 kA per EN 60898, 20 kA per IEC 60947-2, and 5 kA per UL 1077 / CSA C22.2 No.235.

Mounting position any. Sealable, so panel builders can lock the toggle position after commissioning. IP20 with connected conductors; pollution degree 3 (conductive deposits expected).

Frequently asked questions

What is the breaking capacity of 5SY7263-7?
